Abstract: The transfer matrix models of mechanical, electrical and fluid elements are represented in a unified form, and the transfermatrix models of typical elements are derived. The boundary conditions such as node and external disturbance of network are obtained in standard matrices. A universal approach to modeling distributed electromechanical systems in frequency domain is established, which is convenient for large-scale electromechanical systems. The typical complex torsional system and electromechanical coupling driving system are modeled, which proves that the topology structure of large-scale network can be described by coefficient matrices, and the natural frequency characteristics can be simulated with routine matrix manipulation.
