摘要

摘要: 采用静载耦合振动载荷试验研究方法，针对某典型结构件进行了Abaqus有限元仿真模拟，得出了以下结论：1）静载加载预应力与橡皮绳附加刚度对于试验件不同阶次的固有频率及加速度响应的影响规律是不同的，相同条件下不同阶次的振动参数会呈现完全不同的变化趋势；2）静载加载面积对于试验件结构的振动特性的影响非常小，可以忽略不计。综合仿真结果，为某典型结构试验件静载耦合振动载荷动态疲劳试验顺利完成打下基础，并且避免了预试验期间对试验件造成的疲劳累计损伤，对今后的同类型试验有很大的工程指导意义。

Abstract: This simulation study bases on one dynamic fatigue test and aims at the structural dynamic characteristics influenced by the static loads loading. The conclusions can be drawn that: 1) the influences of static loads loading prestress and the added stiffness to the inherent frequencies and acceleration responses of different orders were different, even some appeared totally opposite trend; 2) the static load-carrying area has little influence on the structural dynamic characteristics and can be neglected. At last, the real test was completed successfully by summarizing the simulation results.
