基于分形接触理论,建立了结合面法向接触参数的分形预估模型,通过粗糙表面材料性能参数、法向载荷及粗糙表面的分形参数来预估法向接触刚度和接触阻尼,并对其变化规律进行数值仿真.结果表明:结合面之间的接触处于弹性变形和与塑性变形共存的状态,且小接触点面积的微凸体发生塑性变形,而大接触点面积的微凸体发生弹性变形;法向接触参数与分形参数之间具有较强的非线性关系;同时,法向接触刚度随法向载荷的增大而逐渐增加,但法向载荷对结合面的法向阻尼特性影响较小;仿真结果中极值点的存在,为结合面接触参数的优化设计提供了依据.

采用快速傅立叶逆变换法对路面随机不平度进行时域模拟,建立二分之一车辆动力学模型,应用龙格-库塔法分析了路面等级、车速、载质量和车辆参数对路面动载荷的影响,研究了车辆产生的动载荷规律。仿真结果表明:车辆动载随着路面不平度的增大而明显增大;车辆动载和动载系数随着车速的提高而增大,且在固有频率附近会出现峰值;载质量的增加虽导致动载系数降低,但动载增大,故应严格限制超载现象;增大轮胎刚度和减小悬架阻尼都会引起车辆动载与动载系数的增大,因此,应限制高压轮胎的使用和选择合理的车辆阻尼参数。
