Improved Tilting Method for Automobile Mass Center Measurement Based on Simulation Analysis

Abstract

The Tilting Method(TM) is applied to measure the automobile mass center position widely for simple principles and easy operations. However, the TM has some problems, such as inaccurate calculation of tire force point and large tilting angle of the vehicle, so the Improved Tilting Method (ITM) is proposed in this paper. In the process of running ITM, the tire force direction is always straight up, so the friction and other adverse factors are less than that in TM. ITM applies a combined parallelogram mechanism to keep the supporting plates horizontal. In this research, we study the ITM measurement process by simulation analysis. The research results show that the design scheme and the equipment movement outcomes prove the feasibility and practicability of the ITM.
