本文叙述了确定齿轮传动系统特征对(固有频率和振型)的计算机方法。文中运用有限元法建立等效单元刚度矩阵以集成等效系统的整体刚度矩阵。因此,它可更方便地用变换矩阵求解特征值问题。
This article describes a computerized method of determining the characteristic pairs (natural frequency and mode shape) of a gear drive system. In this paper, the equivalent element stiffness matrix is established by using the finite element method to integrate the global stiffness matrix of the equivalent system. Therefore, it is more convenient to solve the eigenvalue problem using the transformation matrix.
