For the same automobile , the vibration degree or even the type of front wheel shimmy will change with the changing of the whole automobile constructs 同一台车，整车结构发生变化时会改变前轮摆振的激烈程度以至振动的性质。
Through the systematic research of the shimmy of ca10 automobile , we can offer direct theory guidance to reduce or eliminate the shimmy of all kinds of vehicle 通过对解放ca10型汽车前轮摆振的具体研究，可以为减小或消除各种车辆的摆振现象提供理论上的直接指导。
So we have a simulation research on shimmy by computer software and have a study on the effect of system parameters on shimmy , which may offer theory guidance for suppressing shimmy 借助于计算机对摆振现象进行仿真分析，研究系统参数对摆振的影响，可以为探索有效的汽车防摆措施提供理论上的指导。
Though the world boasts the 50 - year ' s history of study on vehicle steering wheel shimmy , and many valuable articles have been published meanwhile , the problem of shimmy is still not solved thoroughly 虽然国内外对摆振现象的研究已有近五十年的历史，并发表了许多有价值的文章，但是摆振问题仍没有彻底解决。
To improve the stability , one common method is to install dampers at the roots of blades . however , commonly used dampers can hardly meet different demands when helicopter working in different conditions 为提高旋翼/机体耦合动稳定性,一般采用在桨叶根部安装减摆器的方法,但目前常用的减摆器很难满足直升机不同工作状态下对摆振器阻尼的不同需求。
On the basis of reference ( superscript [ 6 ] ) , the influence of damping of shimmy damper , moment of inertia of wheel , tire cornering stiffness and strut tilt stiffness on parametric shimmy stability of aircraft wheel is investigated in the paper 摘要本文在文献[ 6 ]的基础上，首次研究了减摆器阻尼、机轮转动惯量、轮胎偏滚刚度、支柱侧倾刚度对飞机机轮参数摆振稳定性的影响。
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。
