| 摘 要： | 文章提出了一种利用机械阻抗求取机械系统传递函数的简便方法 ,它类似于电系统中的复阻抗方法。这种方法将机械系统 3种基本元件固化为类似弹簧的复域元件 ,使求取系统传递函数免去列写微分方程的环节。与电系统稍有不同的是 ,这种方法需将机械系统结构图作适当的改形。改形也很简单 ,只要将串联形式的质量元件改为并联即可。

| Abstract: | A simple method of solving transfer function of mechanical system by mechanical impedance is proposed,which is similar to the method of complex impedance in electrical system. Three basic elements of mechanical system are fixed into complex domain elements as the spring, and the calculus of differential equations is reduced. Differing from electrical system, the structural diagrams of mechanical system need the change of series combinations of mass elements into parallel combinations, which is very simple. |
