| 摘 要： | 将预紧偏心垫层结构简化为中心圆平面问题,建立了动力学模型。采用区间均匀分布描述初值的不确定性,分别数值分析了定系统参数及变化系统参数时系统的转动滑移响应,并应用核密度区间估计的方法研究了初值不确定性对转动滑移响应的影响。加深了对此类结构转动滑移机理的认识,有助于该类结构的防转设计。

| Abstract: | The eccentric pre-tightened cushion structure is simplified as a center-circle plane of the system. Based on this simplification, a dynamic model is established. The uncertainty of the initial value is described as an interval on the uniform distribution. The rotary slips with fixed and variable system parameters are anatomized with numerical calculation, respectively. Furthermore, the uncertainty of the rotary slippage, which was influenced by initial value, is performed by its interval estimation, by means of kernel density estimation. The dynamic behavior and the slip mechanisms, founded by this work, can guideline the slip-forbade design of the eccentric pre-tightened cushion structure. |
