Multibody Dynamic Simulation of Off-Road Vehicles for Load Prediction, Stability, Safety, and Performance

摘要

Multibody Dynamic Simulation has been used to successfully simulate a wide variety of agricultural, construction, and military vehicles and predict the safety, mobility, stability, and operating loads of the complete system. The objective is to predict accurate vehicle behavior under any operating condition and provide the basis for making engineering design changes to improve performance. Vehicles used for agriculture, construction, recreation, and military applications all involve similar modelingrequirements and challenges to account for the wide range of operating conditions. Results of the multibody dynamic simulation process produce time-histories of the position, velocity, acceleration, and reaction forces on all parts. These results have been used to characterize the vehicle performance attributes.
