摘要
通过采用基于正负三角波的时域分析方法,对某舰载机柜进行了在加速度载荷作用下的垂向、横向、纵向的抗冲击性能仿真计算。由计算结果可知,机柜在给定冲击输入载荷作用下,三向冲击仿真结果的最大应力均未超过其材料的屈服应力,机柜在冲击载荷作用下满足设计要求。
By using the time domain analysis method based on Plus-Minus triangular wave,the vertical,transverse and longi⁃tudinal shock resistance of a shipborne cabinet under the acceleration load are simulated.The calculation results show that under the given shock load,the max stress of the three sirection simulation results of the cabinet does not exceed the yield stress of the materi⁃al,and the cabinet meets the design requirements.
