Driving Innovation in Vehicle Dynamics Whitepaper

High performance physical modeling and simulation increases efficiency and productivity in vehicle design

Vehicle manufacturers are constantly faced with the challenge of balancing fuel efficiency and safety against the demands for greater performance and lower development costs. Driven by these needs, a wide range of computer-aided modeling tools has emerged, covering all aspects of the dynamic behavior of vehicles.

However, these tools tend to be very application-specific and use computationally intensive numerical methods, such as finite difference and finite elements. While these are useful for the "off-line" stages in the design process, where time-to-result is not too critical, there is an increasing demand for faster simulations to the point where high-fidelity models need to be run in real-time for hardware-in-the-loop (HIL) testing.

The demand for better understanding of the dynamics, and the ability to produce high-fidelity physical models of vehicle systems that can be used in HIL systems to test prototype controllers, has reached a critical point for many companies. This article explores how the use of model-based designand virtual prototyping allows automotive manufacturers to reduce design and prototyping costs significantly while fulfilling the demands of governments and markets.

SAE Webinar Recording: Physical Models of Automotive Batteries for EV and HEV Applications

This webinar covers new approaches to modeling and simulation for hybrid electric vehicle (HEV) and fully electric vehicle (EV) applications with particular emphasis on the development of high fidelity physical models of automotive batteries. Developed as part of the research program for the NSERC/Toyota/Maplesoft Industrial Research Chair for Mathematics-based Modeling and Design, these models will plug into comprehensive system models for HEV and EV applications. Conventional lead-acid, but also NiMH and Lithium battery models will be presented.

Virtual Driveline Summit

Last week, we attended the 2011 Global Drivetrain Virtual Summit, a free online event that provides the opportunity for you to explore global advancements in drivetrain technology from the comfort of your home or office. The event can be accessed on-demand and attendees can still visit our virtual booth, watch webcasts and more! Don’t forget to check out the webcast: Adjusting Drivetrain Design for EVs and Hybrids.

The Global Drivetrain Virtual Summit is created for design engineers, engineering management, and business leaders to learn the latest about drivetrain development and trends. Hear from leading thought experts on their strategic outlook as they discuss topics such as: What impact will the next generation of passenger cars have on drivetrain design? What will drivetrain trends and challenges be for EVs and hybrids? How will transmissions, axles, and lubricants change?  What are the dangers inherent in marketing environmental performance? What should “green” really mean for your company? What are the benefits, challenges, and future of CVT technology?

In its second year, the virtual summit is the largest online conference developed specifically for those involved in the design and/or implementation of drivetrain technologies including axles, transmissions, and torque control devices for automotive, commercial, and off-highway vehicles. It not only examines the global advancements in drivetrain technology for the ground mobility industry but also addresses regional issues, benefits, and disadvantages on a global scale.

MAPLESOFT IN THE PRESS
Two venerable math programs keep up with the times
IEEE Spectrum magazine, November 30, 2011

When speaking to the developers at Maple, I found them particularly proud of the program's new support for multicore processers, parallel programming for a cluster of local computers, and multithread computing, each of which can dramatically speed up large calculations. For example, they described problems involving sparse linear programming that were unfeasible in earlier versions but can be easily calculated in Maple 15.

Design Engineering, November 9, 2011

In engineering research, detail is vital. Researchers must not only develop models quickly, but they also require in-depth analytical tools to help them understand on a fundamental level the intricacies of their models. Researchers at many academic institutions have adopted MapleSim, advanced physical modeling software from Maplesoft, as a key tool in their engineering research activities (see page 24 using link below).
