| 摘 要： | 用Ansys的DDAM方法进行舰船设备的抗冲击计算时,要求建立的有限元模型的质量单位为磅,长度单位为英寸。技术人员在进行有限元建模时单位一般采用米-千克-秒,所以必须对Ansys程序中各项参数进行单位转换,才能获得正确的仿真计算结果。本文从Ansys在进行抗冲击计算时的各个计算公式出发,分析各个参数的意义以及相互关系,导出了设计冲击谱值的转化关系,利用Ansys的相关命令编制相应的计算程序,方便地完成DDAM的计算工作,对舰船设备的抗冲击计算有一定指导意义。

| Abstract: | We must use the pound and inch as the unit of the finite element model when calculating the shock resistance of the warship equipment with the ansys's DDAM method.But the engineer in our country usually use the m-kg-s as the uinit of the finite element model.For the sake of getting a right result we need to translate the unit of each parameter.This paper begin with the shock resistance formulas,analyse each parameter of the formulas and their correlation,educe the relationship of the parameters.This paper u... |
