摘要

本文给出了结构强迫振动问题的表达式，它具有以下特点:运动方程是在绝对坐标下表示的，允许考虑支承的异步激励，借助Hermite多项式使强迫位移的时间函数平滑，并且可以考虑不服从Rayleigh假设的阻尼。

Time history analysis formulation in SCAD FEA software

This paper provides the formulation of the problem of forced vibrations of structures, which has the following peculiarities: equations of motion are formulated in absolute coordinates allowing to take into account the asynchronous excitations of the supports, smoothing of the time functions for forced displacements with the help of Hermite polynomials, and also the possibility of considering damping that does not obey the Rayleigh hypothesis.
