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.

Design of Experiments (DOE) is a methodology that can be effective for general problem-solving, as well as for improving or optimizing product design and manufacturing processes. Specific applications of DOE include identifying proper design dimensions and tolerances, achieving robust designs, generating predictive math models that describe physical system behavior, and determining ideal manufacturing settings. This seminar utilizes hands-on activities to help you learn the criteria for running a DOE, the requirements and pre-work necessary prior to DOE execution, and how to select the appropriate designed experiment type to run.

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.

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.

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.

Diesel engines manufacturers need to improve engine performances and fuel economy complying with the stricter future emission legislations. Several technologies are now available to achieve such reductions for diesel engines, e.g. exhaust gas recirculation (EGR) systems together with variable geometry turbines (VGT). These technological solutions lead to high engine control complexities, requiring demanding efforts in terms of time and cost for the control design and calibration. Furthermore these issues will increase significantly in the next generation diesel engines with multi-stage EGR and VGT. The challenge is to design highly performing engine control systems able to deal with nonlinear and multivariable problems allowing technological feasibility and cost limitation. This paper examines the adoption of a MIMO nonlinear reference tracking feedback control developed by the joint work between General Motor Powertrain Europe and Modelway.

Failure Mode and Effects Analysis (FMEA) is a systematic method for preventing failure through the discovery and mitigation of potential failure modes and their cause mechanisms. Actions are developed in a team environment and address each high: severity, occurrence or detection ranking indicated by the analysis. Completed FMEA actions result in improved product performance, reduced warranty and increased product quality.

Design reviews are required for ISO 9001:2000 compliance and compatible automotive and aerospace specifications. They are becoming increasingly important in product liability litigation and are accepted as a cost-effective best practice and an effective application of knowledge management, valuable for accelerating the maturity of new products. This seminar describes how formal design reviews can improve products by uncovering potential problems before they are discovered at a later stage of development or application, when the costs of correction are much higher.

Wind noise is an important NVH attribute that can significantly impact customer satisfaction. It is important to assess this attribute early in the design phase. Statistical Energy Analysis (SEA) is an analytical tool that is capable of assessing the wind noise performance of a vehicle in the concept design phase. This workshop starts with an overview of the wind noise problem. Then assessing the wind loads from an experimental and computational approach is discussed. Finally the interior noise assessment via a SEA model is presented. This workshop will be tutorial in nature.

Abstract The inline 3-cylinder engine is taken as an object, the imbalance resultant rotating inertia moment and resultant reciprocating inertia moment generated by piston-crank mechanisms are analyzed. The balance theories of two different balance methods are presented and the additional moment generated through each method is derived. Three different balance conditions are proposed. The imbalance moments and mount reaction forces in each condition are calculated and compared. The powertrain mounting system design method is developed. The optimal mount stiffness not only satisfy the powertrain's natural frequencies and energy distributions but also meet the requirement for mount reaction forces in “50% balance condition”.
