Chassis Dynamometer Simulation of the Tractive Resistance of Vehicle 891375

This paper deduces a mathematical model to determine the road load force using coastdown techniques, and determines the model parameters using numerical integration by analysis in theory and verification in practice. On the basis of analysis and comparison of the vehicle load on the road and on a chassis dynamometer, it gives the relevant transformational relation, constitutes a set of new method of test and computation to determine the road load force by simple coastdown test and provides the foundation for vehicle performance test in doors.
