摘要
本文在机械阻抗法的基础上提出一种新的机械链方法。基本思想是借助机械链图将时域系统转变到复域系统,可以象计算纯粹弹簧系统的等效弹簧一样方便地计算系统及局部的等效复弹簧。新方法简单、直观,便于手算。本文还给出FORTRAN计算程序。
A mechanical link method is proposed based parfly on the mechanicalimpedance method. Time domain system is transformed to complex domain bymeans of mechanical link diagram. For an example, calculation of equivalentcomplex spring is as convenient as equivalent spring. It is simple and direct-viewing for manual calculation. And FORTRAN program is given.
