Development and Analysis of Intermediate Tripped Vehicle Rollover Model (ITRS)

摘要

The report describes the development of the Intermediate Tripped Rollover Simulation (ITRS) which can be used to investigate the rollover behavior of vehicles impacting a roadside curb. The eight degree-of-freedom ITRS model consists of sprung and unsprung masses interconnected through suspension elements. The ITRS model accounts for complete forward, lateral and directional dynamics and is capable of simulating vehicle's skidding motion, simultaneous and oblique impact of the front and rear wheels with a curb, and subsequent tripped rollover under a variety of initial conditions.
