基于COMSOL对介电弹性体曲壳结构的振动特性分析
Vibration characteristics of a dielectric elastomer curved shell structure based on COMSOL
摘要
Abstract
To investigate the influence of dielectric elastomer materials on curved shell structures under externally applied voltage excitation,a finite element model of the curved shell was established in COMSOL Multiphysics for modal analysis.The simulation results were compared with those obtained from the theoretical curved shell model to validate the accuracy of the proposed finite element model.Subsequently,an electromechanical coupling model was developed by integrating the Mooney-Rivlin constitutive model with the curved shell model,thereby establishing a dielectric elastomer actuator model.Numerical simulations were conducted to evaluate the performance of the actuator and analyze its electromechanical characteristics.The results demonstrate that,under voltage excitation,the dielectric elastomer is capable of driving deformation of the composite shell structure.Moreover,the deformation response of the shell with the dielectric elastomer layer is smoother and more stable than that of the shell without the elastomer layer,providing a theoretical basis for subsequent research and practical applications.关键词
