Traction saddle parameters matching analysis of tractor semi-trailer

摘要

In order to analyze the influence of saddle parameters on driving stability of tractor semi-trailer, the steering stability was investigated in the typical operating conditions under the time-domain simulation based on the dynamics model. Then, the paper analyzed the match and the estimation of the effects of parameter variations, these analyses got better values for the design reference. The results show that the changing of saddle parameters effect on the vehicle performance insensitively, their values do not need have very high precision.
