(3)用拉普拉斯变换求非周期激振的响应时间函数x(t)的拉普拉新变换(简称拉氏变换),可写成X(s)=x(t),其定义如下:X(s)=x(t)=■x(t)dt(2.4-58)为了用拉氏变换求解运动方程
(3) The Laplacian transformation (referred to as Laplace transformation) of the response time function of aperiodic excitation using Laplace transform (x) can be written as X (s) = x (t) As follows: X (s) = x (t) = ■ x (t) dt (2.4-58) In order to solve the equations of motion
