摘要
介绍了Abaqus中随机响应分析的特点,简要论述了虚拟激励法的理论基础,介绍了利用Abaqus谐响应分析结果得到随机响应结果的步骤。并以悬臂梁为例,将本文方法和Abaqus中自带随机振动求解器计算结果进行对比。结果表明,两者误差很小,本文方法计算结果可信。
This paper introduces the characteristics of random response analysis in Abaqus,briefly discusses the basic theory of virtual excitation method, and introduces the way to get the random response by using the result of harmonic response in Abaqus. Taking cantilever beam as an example, the suggested method and the method in Abaqus are compared. Results show that the error is very small, and the suggested method is dependable.
