This session explores innovative ideas to enhance automotive safety with improved material constitutive modeling, analysis method developments, simulation and pre/post processing tools, optimization techniques, crash code developments, finite element model updating, model validation and verification techniques, dummies and occupants, restraint systems, passive safety as well as lightweight material applications and designs.
This session focuses on innovative and improved fatigue analysis/design methodologies and problem solving techniques in the ground vehicle industry. The subjects of interest include studies and discussion on (1) structural stress generation, (2) fatigue of metallic material including new lightweight metals, (3) fatigue of non-metallic materials (plastic, elastomer and composites), (4) fatigue of joints and bearings (mechanical, welded, and adhesive-bonding), (5) environmental effects on fatigue performance (elevated temperatures, oxidation, corrosion, and humidity), (6) effect of manufacturing processes on fatigue behavior (surface treatment, residual stresses), (7) vibration fatigue, (8) probabilistic fatigue, and (9) microstructure-mechanics based fatigue.
The focus of this session are the tests and test methods employed in the evaluation of the performance and durability of powertrain (engines, transmissions), driveline (4WD systems, driveshafts, axles), chassis (frame, suspensions, brakes, etc.) and body components, subsystems, and full vehicle systems.
The mobility industry is constantly challenged to provide customers with the ultimate in reliability and durability. As a result, when failures occur during testing or real-world service, it is essential to identify the root cause and take appropriate corrective action in a timely manner. This session will cover failure analysis methodology, fundamentals of failure mechanisms, non-destructive evaluation, fractography, material fatigue testing, fatigue life design for vehicles, material fracture criteria, damage and fracture characterization, fracture prediction in vehicle crash, material fracture behavior in high strain rates, etc., and creative problem-solving case examples of failure analysis and prevention.
Metalcasting is one of the oldest manufacturing processes, dating back over five millennia. However, recent advances continue to expand the horizons of metalcasting: new alloys and new casting techniques are leading to enhanced properties, process modeling and simulation tools are enabling better casting designs, the increasing use of metal-matrix composites is opening new frontiers in casting performance, and additive manufacturing techniques such as 3D printing of pattern materials are reducing lead times for prototype castings. This session will cover the latest developments in ferrous and non-ferrous metalcasting technologies for the mobility industry.
The purpose of this session is to share experiences and lessons learned to advance the technology in the field of thermal management of electric and hybrid vehicle systems. This session presents topics covering both testing and simulation of hybrid and electric vehicle thermal systems.
Climate control is a defining vehicle attribute and is associated with brand image. Thermal performance and quality of climate control are both critical to customer satisfaction. The system has strong design interaction with other vehicle systems, while its primary objective is to deliver thermal comfort and occupant safety with low energy consumption. Localized Comfort, Secondary Fluids, Air Quality, Controls, System Sizing and HVAC consumer interface are just a few of the recent advances.
Thermal Management represents one of the key aspects of the vehicle development. It ensures that the temperatures in the underhood and underbody areas are in desired ranges, that thermal systems operate as designed, and that no component operation is at risk due to excessive temperatures. This session covers the design of thermal components and systems and their vehicle integration.
The Thermal Systems Modeling and Simulation session focusses on state of the art simulation technologies for modeling thermal systems and their application in the development and optimization of vehicle thermal management and fuel economy. The papers in the session will range from empirical, 1D modeling methods to three dimensional CFD models as well as coupled methods.
