The Relationship between Car Caster Angle and the Directional Stability of Car

Abstract

Appropriate alignment parameters may maintain stability of driving and handiness of operation, and automatic returnability of the steering system when the vehicle goes on straight. The alignment parameters of wheel and the steering mechanism are very important factors on tire wear. Among these parameters, the caster angle of the car is one of the most important factors to maintain the stability of the car. Choosing a suitable caster angle will reduce the wear degree of the car and improve the safety factor. Decades of research into the relationship between vehicle stability and caster angle have been exhaustive. From a large number of experiments in the past to the development of modeling software in recent years, people can use modeling software to simulate and obtain more accurate results. It will focus on the analysis methods using several typical modeling software on the market, and finally obtain the quantitative and qualitative relationship between the vehicle directional stability and caster angle.
