  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

    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、輪胎側向剛度、車輪上的不衡質量、輪胎垂向剛度及主銷延長線與地面交至車輪面的對擺振的影響也較大,但不會使系統出現負阻尼;而橫桿阻尼、懸架阻尼與懸架剛度對擺振的影響很小。

  4. With the input of a vibration acceleration history of subway train, a full dynamic analysis of soil - pile - structure is carried out. the propagation of vibration wave on the ground and vibration responses of the huge platform and the storied buildings are analyzed. some conclusions are drawn as follows : ( 1 ) with the increase of the distance to the vibration source, vibration intensity of the ground decreases ; ( 2 ) the vibration intensity of the ground in vertical direction is slightly larger than that in horizontal direction ; ( 3 ) with the increase of the distance to the vibration source, the situation that the vibration intensity of each building in horizontal direction is maximum at highest and lowest story whereas minimum at the middle story changes gradually to that decreasing with the height of building ; ( 4 ) in vertical direction, the vibration velocities and accelerations at the end points of each story of a building are the nominal identical, which indicates that the vertical vibration of them is unanimous ; ( 5 ) the vibration intensity in vertical direction of a building is larger than that in horizontal direction ; ( 6 ) increasing of the elasticity of track is an effective way to abate vibration of ground and buildings

    本文以北京地鐵八王墳車輛段地上超大結構(車輛段大臺及其上的小區樓房)及其地基基礎為研究對象,在研究和分析有關資料的基礎上,用快速格朗日有限差分法軟體flac建立了二維數值分析模型,並以列車振動加速度時程作為模型輸入,進行了地基?樁基礎?地上結構的整體動力學分析,分析了地鐵列車運行產生的振動在地面的傳播規律及其對地上結構的影響,得到了如下結論: ( 1 )隨著與地鐵線路的增大,地面的振動強度有減小的趨勢; ( 2 )地面豎直方向的振動強度較之水方向的略大; ( 3 )隨著與振源的增大,在水方向上,地上各幢樓房的振動強度由底層和頂層的最大、中間層的最小逐漸過渡到沿樓層增高而減小; ( 4 )在豎直方向上,每幢樓各層端的振動速度、加速度完全相同,表明樓房各層在豎直方向上的運動狀態一致; ( 5 )各幢樓房豎直方向的振動強度比水方向的大; ( 6 )增加軌道彈性是減輕地面和地上建築振動的有效途徑。
