动力机器地基随机振动研究
|
摘要
在土层中取一变截面土柱,从一维波动方程出发,采用复弹性模量,计及土的弹性模量沿深度的变化和阻尼影响,推导出动力机器简谐扰力作用下地基土垂直振动的位移,并在此基础上,计算出位于机器下方地基土对机器随机扰力的动力响应.
A soil column with non-uniform section is taken from the infinite subsoil. The vertical displacement of the subsoil is obtained from the one dimensional differential equation of wave propagation. Based on this, the dynamic random response of machine foundation subjected to the exciting force of dynamic machine is computed.
