Efficient Simulation of Vehicle Dynamics with Multi-body Analysis Model

Abstract

This paper describes a new concept of deriving the analysis model for real-time simulation from the model of multibody systems, and presents suitable algorithm for real-time simulation. For real-time simulation, it is shown that the approximation of constraint equation and the transformation of coordinate in equations of motion are effective for reducing calculation. By numerical simulations of automobile, it is shown that the proposed real-time method achieves high-speed calculation with satisfactory accuracy.
