请问spurious oscillation 什么意思?
Assuming no viscous damping may cause spurious, highermodeoscillation in a structure without any other sources of energy dissipation.
在一篇文章中看到这段话,spurious, highermode oscillation 不是很理解,文章后面还有提到spurious modes,麻烦解释一下这个概念,谢谢! highermode oscillation --高阶模态振动
spurious oscillation--找不到理由的奇怪
