【摘要】 本文根据D H坐标系的规定,建立了双横臂独立悬架四杆机构各杆的杆坐标系,接着求得各杆坐标系之间的转换矩阵,使得可以完全运用矢量代数的知识,对其运动规律进行了分析,推导出了主销内、外倾角,车轮外倾角,前束,侧倾中心高度,抗点率等运动变量的表达式。此法无须求解三元二次方程组,易于编程。更多还原

【Abstract】 This paper, based on the rules of D-H coordinate system, sets up each member coordinates of the four-bar linkage of the double wishbone independent suspension, then gets the matrices of transformation between those coordinates. Consequently it is possible to analyze the displacement, velocity and acceleration of the independent suspension with vector, and to deduce the representations of camber angle, caster angle, steering axis inclination, toe-in, the height of roll center anti-dive rate and so on. This method is easy to use without need to solve the systems of quadratic equations with three variables, especially suitable for programming.更多还原
