运用概率统计的方法,对机械结构在阶跃干摩擦函数及二阶线性弹性函数作用下的振动数学模型进行分析,并给出汽车对应二阶线性弹性力的位移和加速度输出均方差,以便更合理地选择对汽车振动产生重要影响的某些参变量。
Using the method of probability and statistics, the mathematical model of the vibration of the mechanical structure under the step-dry friction function and the second-order linear elastic function is analyzed and the mean square error of the displacement and acceleration output of the second-order linear elastic force of the vehicle is given. Reasonably choose certain variables that have a significant impact on vehicle vibration.
