Book Abstract

第14章 瞬态分析
瞬态动力学响应是工程中关注的问题。瞬态分析可以确定承受任意的随时间变化载荷结构的动力学响应。闪此,可用其分析确定结构在静载荷、瞬态载荷和简谐载荷随意组合作用下随时间变化的位移、应变、应力及作用力情况,帮助设计人员更好地模拟结构承受实际工况时的响应情况。
学习目标:
理解进行瞬态分析的步骤。
练习使用ANSYS wbrkbench进行瞬态分析。
14.1瞬态分析步骤
14.1.1瞬态分析概述
相对于谐响应分析,瞬态分析以计算开始激励时发生的瞬态振动为主。相对于静态分析,瞬态分析需要进行更多的计算以得到时间历程下结构的响应情况。为了提高计算效率,通常进行如下准备工作。
简化模型,越简单的模型越能节省求解时间,提高工作效率。措施包括使用更多的梁单元和集中质量。
如果分析中包含非线性,可以通过进行静力学分析尝试了解非线性特性如何影响结构的 响应,而有时候,在动力学分析中不必包括非线性也可以很好地模拟实际工况。
通过模态分析计算结构的固有频率和振型,即可了解这些模态被激活时结构如何响应。固有频率同样也对计算正确的积分时间步长有用。
对于非线性问题,考虑提取模型中的线性部分的子模型进行分析。
