摘要
在运输情况下,电子机柜的随机振动影响产品性能。对于某大型电子机柜,利用仿真结果对有限元模型进行修改,找出设计薄弱环节,通过结构设计参数优化以达到行业标准或国家标准要求。
In transportation, the performance of production can be affected by random vabration of electric cabinet. For a huge electric cabinet, finite element model will be modified using simulation results, and weak part in design will be found out. The parameters of structural design can be optimized to achieve professional and national standards.
