LS-DYNA常见问题汇总 1.Consistent system of units单位制度 相信做仿真分析的人第一个需要明确的就是一致单位系统(Consistent Units)。计算机只认识0&1、只懂得玩数字,它才不管你用的数字的物理意义。而工程师自己负责单位制的统一,否则计算出来的结果没有意义,不幸的是大多数老师在教有限元数值计算时似乎没有提到...
将工程中的某些结构简化为刚体,不但可以大大简化分析过程,而且可以保证分析的精度。LS-DYNA程序使用刚体算法主要是为了节省计算资源,减少计算用时。只要刚体简化得当,遇到很多问题您都可以像马大师一样,一招接化发搞定。 本文要点如下。 1 引例:落锤冲击 计算下图所示冲击模型,尺寸、速度、材料均见下文。
