Engineers are taught to create designs that meet customer specifications. When creating these designs, the focus is usually on the nominal values rather than variation. Robustness refers to creating designs that are insensitive to variability in the inputs. Much of the literature on robustness is dedicated to experimental techniques, particularly Taguchi techniques, which advocate using experiments with replications to estimate variation. This course presents mathematical formulas based on derivatives to determine system variation based on input variation and knowledge of the engineering function.

Today's transportation industries are facing multi-disciplinary challenges. The product design and development process challenges often contradict each other, for example cost, weight, quality and performance. A central challenge is the need for cost and mass reduction to compete in the global market, while continuing to meet all new and existing requirements for quality and performance. Accelerated Concept to Product (ACP) Process is a performance-driven, holistic, product design development method intended to create a balance between structure and strength, synchronizing the individual facets of the product development process.

Recent years have witnessed an increase in the number of electrical loads being driven by semiconductor devices in the body control module or BCM rather than by relays in a typical truck with a 24V vehicle power net. This paper presents the major challenges caused by the higher voltage class of the truck supply and the longer cables, followed by an analysis of some key issues related to the design of truck BCMs to drive different loads. It offers some general guidance on practical design issues to BCM designers, such as an understanding of the advantages and disadvantages of different BCM architectural topologies, how to make a choice between a relay or a semiconductor driver, knowledge of the requirements of semiconductors used in truck applications etc.

The application of Artificial Intelligence (AI) in automotive industry can dramatically reshape the industry. In past decades, many Original Equipment Manufacturers (OEMs) applied neural network and pattern recognition technologies to power train calibration, emission prediction and virtual sensor development. The AI application is mostly focused on reducing product development and validation cost. AI technologies in these applications demonstrate certain cost-saving benefits, but are far from disruptive effect. The disruptive impact can be realized when AI application finally bring cost-saving benefits directly to end users. For example, automation of vehicle or machine operation can dramatically improve the efficiency. However, there is still a gap between the current technologies and the one that can fully enable the vehicle or machine intelligence including reasoning, knowledge, planning and self-learning.

Design and evaluation of construction equipments and vehicles constitute a very important but expensive and time consuming part of the engineering process. This is especially so because of the large number of variants and the relatively small production volume of each variant leading to large costs of engineering and design of vehicles as a proportion of total sales. A simulation based methodology could potentially reduce the cost and time of the entire design process. In this study, we look into an alternative simulation based approach to the design process. However, given the enormity of the task, we limit the scope of this investigation to design evaluation and improvement for thermal considerations only. In particular, thermal evaluation of the electronic control units are looked into.

The hydraulic brake products like brake calipers, master cylinders and boosters are the foundation of today complex vehicle brake systems. The state of the art application leads very often to an individual design, due to the fulfillment of customer requirements within the available installation space. Also the enormous pressure on cost and time require optimized design processes. Therefore Continental developed the product configuration software CoBra. Within this software tool, the engineering is able to react very fast on demands. Starting with the brake sizing parameters and the customer interface definition, CoBra supports the design engineer to select the necessary components and positioning them accordingly, considering the actual design standards. The data based configuration software collects all necessary design parameters and provides an export to parametric CAD start up models.

This reseach presents the energy recuperation eddy current retarder (ERECR) which could offer a solution for the energy consumption and overheating issues of the conventional eddy current retarders. The ERECR consists of 3 main systems, namely Eddy Current Braking (ECB) system, Energy Recuperation (ER) system and Electrical Control System. The ER system which could recycle the kinetic energy from constrant speed downhill and the braking condition is mainly concerned in this research. By proposing a novel designed generator integrated with the dual-plate eddy current retarder, the ER system could generate electric energy to fulfill the energy demand of ECB system while offering respective braking torque. First, the energy flow for the vehicle braking and degrading was analyzed and the energy recovery potential under these conditions was calculated.

The trend towards all-electric aircrafts leads to an increased complexity and extent of the electrical power system and its interactions with adjacent systems. These interactions need to be analyzed in detail, to identify safety bottlenecks as well as beneficial synergies. Consequently, the system specific design paradigm has to be dissolved, to utilize the full potential of more-electric applications. In this regard, an approach to investigate the interactions between the power systems and innovative flight controls of a regional aircraft is pursued at the Hamburg University of Technology. In a first step, flight dynamics analyses were conducted to identify the distinct requirements for the flight controls. The design of electrically actuated flight controls and an electrical power system architecture for the regional aircraft shall be presented in the intended paper.

In the aircraft design process there are the occasional bolted joints with opposing surfaces that are not parallel to each other. This can necessitate manufacturing to machine a spot face into the structural surfaces for the bolt head and nut to seat on. Typically this process is done manually by two workers with all process verification being done visually. Additionally, the nature of airplane structure often requires one worker to be inside a confined space to monitor the process. With this in mind, a tool was requested to reduce the number of workers required, remove workers from confined spaces and ensure a robust method for process validation. The critical technology that would have to be developed was a device that could fix itself into an existing hole, measure the surface of which the hole exited and then machine a spot face into that surface to a specific calculated depth. The device would only require a single operator to install and start the machine in a given hole.

In recent years, there has been an increase in the use of Unmanned Aerial Systems (UAS) in both civilian as well as military sectors for a wide range of applications including aerial reconnaissance of military targets, monitoring traffic, geological mapping, search and rescue among others. Typically with the use of UAS, there is a premium on total weight and cost, in order to maximize their payload potential and as a consequence, the use of redundant sensors is uncommon. In addition, UAS have gained wide acceptance as the platforms of choice for implementing high risk/high reward flight control algorithms, especially addressing sensor and actuator failure scenarios, thanks to the low logistical burden. This research effort describes the design and simulation of a distributed Neural Network (NN) based fault tolerant flight control scheme for sensor and actuator failures and the interface of the scheme within a simulation/visualization environment.

Hardware-in-the-loop (HIL) testing is regarded as the tried-and-tested method for function, component, integration and network tests for the entire system. It is indispensable in the software development process for control units and has been an integral part of numerous companies’ development process for years. This holds especially for model based design. Since all the time HIL testing is applied, users continuously optimized their processes. This reflects the need to adopt testing processes to changing conditions, which may be imposed by industry changes. A well-known fact is the division of tasks between different sites of a single company or between the system integrator and its suppliers. Thus, companies, departments or teams are often located in different buildings, towns or even countries. This division of tasks imposes a challenge for the integration testing of systems, since there are significant interdependencies between the controls of aircraft systems.

Design for Assembly is the concept of carrying out critical thought early in the design stage to create assembly easement at the production stage. In the aerospace industry products have very long lives, frequently being optimised rather than introducing new products. This has meant that older products that are stable cash cows have not benefited from new Design for Assembly Methods and manufacturing equipment and tooling suffer from obsolescence. It has been established that approximately 80% of overall product cost is determined at the design stage and thus existing products suffer from preloaded costs. This paper takes existing Design for Assembly methodologies and analyses them with respect to the unique challenges involved in legacy product redesign. The methodology developed is both a quantitative solution coupled with thought channelling processes. An existing case study looking at optimising the installation of small butterfly brackets is used to test this methodology.

Current assembly systems that deal with large, complex structures present a number of challenges with regard to improving operational performance. Specifically, aerospace assembly systems comprise a vast array of interrelated elements interacting in a myriad of ways, resulting in a deeply complex process that requires a multi-disciplined team of engineers. The current approach to ramp-up production rate involves building additional main assembly fixtures which require large investment and lead times up to 24 months. Within Airbus Operations Ltd there is a requirement to improve the capacity and flexibility of assembly systems, thereby reducing non-recurring costs and time-to-market. Recent trends to improve manufacturing agility advocate Reconfigurable Assembly Systems (RAS) as a viable solution. Yet, adding reconfigurability to assembly systems further increases both the operational and design complexity.

Within the “Industria 2015” Italian framework program, the HI-ZEV project has the aim to develop two high performance vehicles: one full electric and one hybrid. The hybrid vehicle is a sport car with an internal combustion engine with a maximum power of 300 kW and an electric motor with a maximum power of 150 kW. It is equipped with a 400 V, 15 Ah storage system. Special batteries are required due to the high values of discharge current needed to supply the electric subsystem (up to 25 times the nominal current). Also a dedicated cooling system has been designed, to avoid a dangerous rising temperature, due to such high currents. The cells used have been the Demon 5Ah OCCL (Oxygen-Cobalt-Carbon-Li-Ion technology). Every single module is composed by 6 cells in series with 22.5V of nominal voltage, while the battery pack is made with 18 modules in series and 3 in parallel.

Emission requirements for diesel engines are becoming increasingly strict, leading to the increase of engine architecture complexity. This evolution requires a more systematic approach in the development of control systems than presently adopted, in order to achieve improved performances and reduction of times and costs in design, implementation and calibration. To this end, large efforts have been devoted in recent years to the application of advanced Model-Based MIMO control systems. In the present paper a new MIMO nonlinear feedback control is proposed, based on an innovative data-driven method, which allows to design the control directly from the experimental data acquired on the plant to be controlled. Thus, the proposed control design does not need the intermediate step of a reliable plant model identification, as required by Model-Based methods.

Main aim of this paper was to exploit the well-known Willans line method in a twofold manner: indeed, beyond the usual identification of Willans line parameters to enable internal combustion engine scaling, it is also proposed to infer further information from identified parameters and correlations, particularly aiming at characterizing mechanical and frictional losses of different engine technologies. The above objectives were pursued relying on extended experimental performance data, which were gathered on different engine families, including turbo-charged Diesel and naturally aspirated gasoline engines. The matching between Willans line scaled performance and experimental ones was extensively tested, thus allowing to reliably proceed to the subsequent objective of characterizing mechanical losses on the basis of identified Willans parameters.

Alternative vehicle powertrains (hybrid, hydrogen, electric) are the only possible solution for environmental problems afflicting urban areas. Electric and hybrid vehicles are now slowly taking place in the automotive sector, while mostly thanks to the international regulations that incentive manufactures to have a share of such vehicles in their fleet. On a Well To Wheels (WTW) basis, the most effective alternative powertrain is surely represented by fuel cell vehicles, which convert fuel energy directly in electric energy with a higher overall conversion efficiency than a thermal engine. The design and optimization of this kind of vehicles and powertrains, however, is not straightforward, and can be guided by proper mathematical modeling approaches, considering energetic as well as physical characteristics of all the components.
