Maplesoft expands scope of automotive models with tyre components

The MapleSim Tire Component Library provides MapleSim users with industry-standard tyre force model components. In addition, linear and user-defined tyre models are available to provide flexibility for investigation and analysis. With the easy-to-use point-and-click MapleSim graphical environment, these fully parameterised force models can be integrated into existing vehicle dynamics models by simply dragging the component into a diagram and connecting the component to the vehicle model.

“This announcement should come as exciting news to the automotive industry,” said Laurent Bernardin, Executive Vice President, Research and Development, Maplesoft. “The additional components pave the way for engineers in the automotive industry to produce more accurate and complex real-time models of vehicle systems. Research and analysis in the areas of vehicle dynamics and stability control can also be expanded with this new tool.”

With the MapleSim Tire Component Library, users receive the following key features:

o Kinematic quantities, such as slip angle, longitudinal slip and inclination angle are derived automatically and available to the user. These quantities are used to determine the tyre forces and moments.
o Engineers can control how the tyre slip and rolling radius are calculated and include tyre transients through differential equations involving relaxation lengths.
o Support for the following industry-standard tyre models: Fiala, Calspan and Pacejka 2002. For custom research and development applications, user-defined tyre models can be constructed easily using an intuitive interface.

Since the MapleSim Tire Component Library is a fully integrated add-on package to MapleSim, the tyre model components can take full advantage of features available to MapleSim components.
