外力冲击二级隔离系统参数设计DEM研究

DEM Research on Parameter Design for Two-level Isolation System Impacted by External Force

提出了外力冲击的二级隔离系统的 DEM模型。计算机仿真研究了冲击持续时间及具体波形与隔离系统的动态特性的关系 ,同时也研究了系统的非线性对系统动态性能的影响。

The discrete element method (DEM) model of two level isolation system impacted by external force is developed. The relations between the dynamics characteristics of two level isolation system and the duration times and wave type of impact are studied together with the non linear effects on the dynamics characteristics of the system by computer simulation. A new approach is provided for parameter design of two level isolation system impacted by external force, consequently.
