摘要文章介绍了产生突发不平衡的装置， ?述了不平衡质量产生的原理及控制方法，最后进行了突发不平衡动态响应实验。 - 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。 - In order to solve it radically , making power assembly of bj1036e2f1 light truck the research object and through dynamic simulation analysis of power assembly , this thesis obtains the distribution rules of forces of the bolts linking three shells mentioned above and the relation between forces of the bolts and rotate speed of engine . after finite element mode analysis of these three shells , inherent frequency and vibration model of shell of power assembly are gained , and thus its dynamic character is realized . based on computer simulation analysis , experimental model of power assembly is acquired by vibration test and strength test of shell of power assembly , and the relation of forces of the shell and rotate speed of engine and imbalanced mass of rotate components is studied
