在ANSYS中,冲击响应谱(Shock Response Spectrum, SRS)是一种用于评估结构在动态载荷下的耐久性的方法。q值是SRS曲线的一个重要参数,用于衡量对应于特定频率的SRS峰值的阻尼损耗。 为了写出与ANSYS中冲击响应谱中的q值相关的参考内容,可以从以下几个方面展开讨论: 1.冲击响应谱的基本概念: -介绍冲击响应谱的定义和作...
冲击响应谱(Shock Response Spectrum, SRS),又称“冲击谱”,用于描述一系列单自由度质量阻尼系统受冲击时各单自由度系统的响应最大值与单自由度系统的固有频率的关系。一般来说,冲击响应谱是一个动态系统对给定瞬态输入的峰值响应与该动态系统固有频率之间的函数关系图。下图所示为一系列单自由度“弹簧-质量-阻尼”...
5) Shock test. The input excitation is specified in terms of the Shock Response Spectrum (SRS). The output should be the spectrum or time history at any specified point. Could you please teach me how to simulate these different tests on Ansys? Thanks and regards November 22, 2022 at 7:...
