第四，对测试过程中数据定标进行了详细研究。对数据采集、数据处理作了简要分析。 - 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。 - This dissertation has presented a new method on the measuring and checking procedures of the dynamic unbalance of the motorcycle crank and made a deep research on its measuring device . what have been done is as follows : firstly , the dissertation has thoroughly discussed the basic theory of rotor unbalance such as its varieties ， characters and rules of the movement which is under the excitation of the inertial force and inertial moment induced by the unbalance mass . it also has deeply expounded the dynamic mechanics of the specially formed components ? crank , especially in the area of the crank integrated with shaft and piston
