【摘要】 汽车的转向特性是研究及评价一辆现代汽车的最重要特性之一。本文在分析已有资料的基础上,建立一个多自由度非线性的数学模型,编制了求解方向盘固定转角输入时的稳态响应及方向盘阶跃转角输入时的瞬态响应的程序,以用于分析某些汽车结构参数对汽车转向特性的影响。本文以北京吉普BJ-212A为例,测定该车的有关参数,计算了若干种改进设计方案的转向特性。其中一个方案的稳态响应计算结果用试验作了验证。

【Abstract】 Steering characteristics is one of the mostimportant characteristics for studying and evaluation of modern road vehicles A rather general non-linear mathmatical model with multidegrees of freedom was build based on studying relevant literatures.Computer programms were worked out for calculating the steady response to a fixed steering wheel angle input and the transient response to a step steering wheel angle input to analyze the effects of some automobile parameters on steering characteristics.In this paper the related parameters of a 4×4 light truck have been measured and the steering characteristics of it’s several varieties were calculated.One set of calculated data was compared with road experiment results.
