  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

    橫拉桿剛度、輪胎的側偏剛度、轉向機剛度、轉向機阻尼、繞主銷當量阻尼、主銷后傾角、輪胎拖距是影響擺振的敏感性參數,適當調節某一參數可引起系統的負阻尼,使系統產生自激擺振;輪距、輪胎側向剛度、車輪上的不平衡質量、輪胎垂向剛度及主銷延長線與地面交點至車輪平面的距離對擺振的影響也較大,但不會使系統出現負阻尼;而橫拉桿阻尼、懸架阻尼與懸架剛度對擺振的影響很小。
  2. This paper firstly analyses the various reasons and dangers caused by unbalanced rotors according to information and experiments, after these, different balancing methods for different types of unbalancing rotors were discussed. on the basis of the theory that discussed above, the paper analyses different types methods of measuring especially wattmeter measuring system and character of signals of hard bearing dynamic balancing system and designs a hard - bearing microcomputer - based measuring system for different types of hard bearing dynamic balancing machines. using advanced technology both in hardware and software of the modern, this system aims to reach the general goal of great mass, high precision, easy - to - operate and lows cast
