Developments of experimental and theoretical schemes in various engineering disciplines are accompanied with growing complexity. This complexity can be attributed to extensive acquisition of measured data as well as higher order levels of computational analysis. One significant feature of this complexity is the presence of uncertainty, which is inherent in both experimental and analytical engineering schemes. This session is intended to bring a collection of papers on current methods and new directions in treating the presence of uncertainty in: 1) data acquisition and analysis and 2) in the mechanical systems. Papers are specifically sought in new analytical and data quality assurance methods for treating uncertainty.

Abstract: **Driver modeling is essential to both vehicle design and control unit development. It can improve the understanding of human driving behavior and decrease the cost and risk of vehicle system verification and validation. In this paper, three driver models were implemented to simulate the behavior of drivers subject to a run-off-road recovery event. Target path planning, pursuit behavior, compensate behavior, physical limitations, and neuromuscular modeling were taken into consideration in the feedforward/feedback driver model. A transfer function driver model and a cost function based driver model from a popular vehicle simulation software were also simulated and a comparison of these three models was made. The feedforward/feedback driver model exhibited the best balance of performance with smallest overshoot (0.226m), medium settling time (1.20s) and recovery time (4.30s).

Cylinder head design is one of the most involved disciplines in engine design. Whether designing an altogether new head or revamping an old one, several different coupled and inter-dependent technologies ranging from heat transfer, 0fluid flow, combustion, material non-linearity, structural and fatigue have to be accounted. Simultaneous designing of ports, jacket and combustion chamber leads to cylinder head design, which is then tested for its strength and durability. Traditionally a series of analytical, empirical, test-based and simulation based exercises are conducted to design cylinder heads. With increasing pressure on reducing cost and turnaround time, focus on moving towards a quasi simulation based design and development of cylinder heads is gaining strength. This paper talks about how a simulation driven process for cylinder head design can be developed.

In this paper the effects of the adoption of a Partially Stratified Charge (PSC) combustion strategy on the performance of a lean natural gas fueled engine are compared with the ones obtainable with a strategy based on the traditional Homogeneous Combustion process. To that final aim, a CFD 3D model, based on Large Eddy Simulation, has been used to represent the combustion process on a dynamic full 3D engine mesh, taking into proper account all the different phases (intake, combustion and exhaust). The combustion model has been validated via comparison of the flame front development in a Constant Volume Combustion Chamber (CVCC), and then applied to study a single cylinder engine research engine to have an idea of the impact of the real cylinder flow onto the combustion processes and its influence on the main engine parameters. The benefits of the PSC combustion have been checked via several indicators, such as pressure history, energy heat release and flame front turbulent speed.

In this work, a consistent transport and mixing model is derived and validated that calculates the same mixing in thermodynamic multi-zone space as in spacially resolved physical space. The transport and mixing model is developed using a turbulent channel flow as simplified domain. This physical domain of a direct numerical simulation (DNS) is divided into zones based on the quantitative value of transported scalars. Fluxes between the zones are introduced to describe mixing from the transport equation of the probability density function based on the mixing process in physical space. The mixing process of further scalars can then be carried out with these fluxes instead of solving additional transport equations. The relationship between the exchange flux in phase space and the concept of scalar dissipation are shown and validated by comparison to DNS results.

Estimating the real-time (RT) behavior of software architecture in embedded system is very difficult and critical. Most of the current approaches rely on engineering judgment or actual measurements performed during integration testing. Both approaches are not error proof and can yield to RT constraints violations discovered during simulation of RT architectural design or during product validation. Impact on project could even be a CPU change. In this work, OS process execution time (ET) is used as the basic element of RT architectural design. First, OS process ET is predicted using machine learning (ML) algorithms, based on previous SW releases. Different types of features (e.g. number of static architecture requirements, hardware factor, seniority index), are proposed as inputs (feature vectors) to multiple ML classifiers in order to predict processes ET. Multiple ML techniques (e.g.

In many engineering domains like aerospace, vehicle or engine design the analysis of flow fields, acquired from computational fluid dynamics (CFD) simulations can reveal important insights on the behavior of the simulated objects. However, the huge amount of flow data produced by each simulation complicates the data processing and limits the application of data mining and machine learning tools for the flow analysis. The paper introduces a compact stream line and feature based representation of three dimensional flow fields, in order to overcome this limitation. The compact representation defines the basis for a subsequent quantification of flow field similarities.

For an engine stop-start powertrain, an electrically-driven auxiliary pump is typically implemented to maintain the transmission line pressure as required to lock-up the 1st gear clutch during engine auto-stop conditions. Upon releasing the brake pedal, the transmission engages into first gear with the objective to accelerate the vehicle in a responsive manner. A normally-engaged dual-piston clutch concept is designed to keep the 1st gear clutch locked-up during engine auto-stop conditions with the intention to eliminate the auxiliary pump without compromising vehicle performance. This dual piston clutch concept requires a relatively low line pressure to release the normally-engaged clutch when needed, thus, minimizing the hydraulic pumping work. To explore the functionality of this concept under a wide-open-throttle (WOT) auto-start transition, modeling and simulation of the normally-engaged dual-piston clutch is completed.

Vehicle simulation models are essential throughout the development process in the automotive industry. The benefit of using models starts when post processing measurements performed on market vehicles, continues when assessing for target setting and components selection, and permits the development of controllers and strategies easing optimization of the vehicle. This paper gives an overview of methodologies based on longitudinal dynamics for the simulation of vehicle performance and fuel economy. These methodologies can be applied to a variety of architectures ranging from quadricycles to trucks and from combustion to hybrid. The main difference between methodologies is the solver, which influences the results and thus the area of application. The two main trends, namely forward and backward simulation, have features that make them not able to fully describe the behaviour of a real vehicle.
