A Study on the Finite Element Modeling of Rubber Dampers for Aerospace Computer
The establishment of the finite element model about rubber dampers for aerospace computer is the difficulty in FEA. In this paper, the relevant literatures are studied, and two modeling methods for rubber dampers are proposed, and the finite models of the rubber dampers are established,which are validated respectively, and the scope of application about the two models is summarized.

表1 正弦扫描振动试验条件 |
频率范围(Hz) | 量级 |
---|---|
5-8 | 8.87mm |
8-30 | 2.24g |
30-50 | 4.2g |
50-400 | 2.24g |
注:量级中单位为mm的是位移量,单位为g的是加速度值。扫描率: R=1oct/min,振动方向为减振器阻尼圈的轴向 |
