悬架刚度的英文

例句与用法

1. Those sensitive parameters making system have negative damping and occur self - excited shimmy are horizontal pulling lever rigidity , tire sideslip rigidity , steering gear rigidity and damping , kingpin equivalent damping , kingpin caster angle , tire drag . and wheel center distance , tire side rigidity , vehicle wheel unbalanced mass , tire vertical rigidity , and distance from kingpin center to the vertical central line plane of tire have great influence on shimmy , but they do n ' t make the system have negative damping . and horizontal pulling lever damping , suspension damping and rigidity have very small influence on shimmy
   横拉杆刚度、轮胎的侧偏刚度、转向机刚度、转向机阻尼、绕主销当量阻尼、主销后倾角、轮胎拖距是影响摆振的敏感性参数，适当调节某一参数可引起系统的负阻尼，使系统产生自激摆振；轮距、轮胎侧向刚度、车轮上的不平衡质量、轮胎垂向刚度及主销延长线与地面交点至车轮平面的距离对摆振的影响也较大，但不会使系统出现负阻尼；而横拉杆阻尼、悬架阻尼与悬架刚度对摆振的影响很小。
2. The random excitation of the four wheels is used as the input of this system . the changing rule of vertical displacement , three directions of acceleration power spectrum density function of person - chair system of model ca - 141 and etc . in the frequency domain is simulated using matlab . the rationality of the model is analyzed and validated by comparing of relevant testing results and theoretic analysis
   以频域内四轮随机激励作为系统输入，用matlab仿真低地板城市客车等三种车型人椅系统三向加速度功率谱的变化规律，逐项分析车速、悬架刚度与阻尼参数变化对车辆平顺性的影响，通过与相关研究结果的比较及理论分析验证了模型的合理性。
