摘要
针对舰船设备冲击特性计算中存在的困难,采用基础激励影响系数建立起多自由度系统在基础冲击作用条件下的动力学方程,分析了不同加速度冲击转换为速度阶跃的具体方法及转换过程中产生的误差,提出了采用大质量法和相对速度法两种技术途径来解决A NSYS等仿真软件中的速度初值输入问题。
In view of the difficulties in calculating the shock property of ship-based equipment, the dynamics equation under base shock is founded with base excitation effect coefficient. The way that different accelerating shock is transformed into velocity step is analyzed and the transformation error is also calculated. The big-mass method and relative velocity method are submitted to solve the problem of value inputting for initial velocity in ANSYS.
