摘要
以典型焊接夹具为例,通过有限元方法,比较不同焊接模拟及螺栓约束模拟的差别,并与该结构的试验结果进行比对,得到较为快速准确的模态分析建模方式。进一步地将该建模方式应用到某卫星资源舱的焊接试验夹具,对比其模态仿真结果与试验结果,并综合考虑振动台的影响,进一步验证其在复杂结构分析时的有效性。
This paper jig structure with and sate cons efficient modeli llite resource c uses the finite element method to compare the modal results of typical welded different welding and bolt-constraint simulation in order to find the effective ng method. And then the method is utilized to the modal analysis of test jig of a abin and comparison is made to verify the validity of the modeling method under the ideration of influence of shaker table.
