A new collaborative MDO strategy for improving vehicle design at Ford

Ford Motor Company achieves streamlined, multi-user design process management by expanding its Multidisciplinary Design Optimization approach at enterprise level with ESTECO Collaborative web-based environment.

Two design projects highlight how Ford pools resources from different departments around the world and funnels this knowledge into the vehicle design process

Reliability analysis and optimization of ADAS systems

The validation of ADAS systems today is still a difficult task to achieve as it is unclear what the load cases getting the system to fault are considering that the ADAS system needs to be operational all the time, not to mention the need to fulfil the Euro NCAP requirements. It is therefore mandatory to develop a simulations approach in which the ADAS control systems, integrated with sensors and actuators, vehicle dynamics, inter-vehicle behavior and traffic environment are simulated.

Increasing passive safety performances using an automatic CAE methodology

In the automotive industry, safety requirements are more and more stringent leading to engineering challenges in finding the best tradeoff between crashworthiness performances, structure weight, design and production costs. The goal of the activity is to develop an automatic optimization work flow for a car door. The final objective is to fulfill the safety requirements and obtain the best rating in the pole test.​

Effective toolchain for the model based development of an EUVI exhaust aftertreatment system

BASF, as a leading global catalyst supplier, was approached by a commercial truck manufacturer to improve cost and performance of the current EUVI production exhaust after treatment system.

Optimizing Seat Belt and Airbag Designs for Rear Seat Occupant Protection in Frontal Crashes

Recent field data have shown that the occupant protection in vehicle rear seats failed to keep pace with advances in the front seats likely due to the lack of advanced safety technologies. The objective of this study was to optimize advanced restraint systems for protecting rear seat occupants with a range of body sizes under different frontal crash pulses.

Application to Short Fiber Reinforced Plastic (SFRP) Microstructure Optimization for NVH improvement

The role of simulation is of critical importance to drive the powertrain design for Noise, vibration, and harshness (NVH) on a Component, Sub-System and System Level.

Multivariate Optimization and 1-D Simulation of a High Performance Single Cylinder Engine for The ESTECO Academy Design Competition

Organized in partnership with Aprilia Racing and Gamma Technologies, the ESTECO Academy Design Competition 2016 was open to teams of undergraduate and graduate engineering students. The challenge was to improve the design of a 4 stroke single cylinder engine through multidisciplinary optimization (using modeFRONTIER) and 1-D simulation of the engine system with GT-Suite. 

Optimization: I do not think you know what that word means

While many techniques and tools are available to perform an optimization analysis, during the relative quick pace of automotive development the difficulty is having the time to use these tools to find an optimal solution considering the number of variables and types of analyses that need to be included in the process. 

The Future of Modeling, Simulation and Optimization at Cummins

Cummins uses modeFRONTIER to facilitate “system-level” design optimization studies, quantifying the trade-offs across system-level performance to detailed component design.
