论文摘要

冲击响应频谱(SRS)是一种被广泛接受的冲击测试规范的方法。但是,作为至上的SRS,SRS的保守性过高,无法完全描述各种冲击环境的相对严重性。这项研究引入了冲击响应矩阵,可以使用单数值分解方法从中提取休克严重程度(SSI)。基于SRS和SSI,引入了双光谱,以确定其至高无上和imimum之间的冲击严重程度范围。通过有限元模拟讨论和验证了各种冲击信号的相对严重程度的评估。

Shock response spectrum (SRS) is a widely accepted method for shock testing specification. However, SRS, as a supremum, is over-conservative and cannot fully describe the relative severity for various shock environments. This study introduces shock response matrix, from which shock severity infimum (SSI) can be extracted using singular value decomposition method. Based on SRS and SSI, dual spectra are introduced to determine the range of shock severity between its supremum and infimum. The evaluation of the relative severity of various shock signals is discussed and validated by finite element simulations.
