Abstract：In order to solve the repeatability modeling and parameter optimization of Abaqus and improve the efficiency of simulation analysis，the parametric modeling program of three-layer composite laminates is studied. The relevant scripts are writen by Python language and Abaqus built-in secondary interface to complete the development of the parametric modeling program of laminate multi-parameters，the interactive interface of Abaqus and the calculation program of damping loss factor are used to evaluate the damping performance. An example analysis of the optimization problem of laminates shows that the similar laminates can be quickly modeled by the program，the damping loss factors of structures with diffrent parameters are obtained，and finally the discrete optimal damping performance parameters are obtained.
