针对准零刚度隔振器因结构复杂而难以在有限元模拟过程中实现较好收敛的问题，本文利用ABAQUS软件的多体分析功能，解决了准零刚度隔振器建模分析过程中的简化模拟与收敛性问题，形成了针对准零刚度隔振器性能研究的有限元模拟方法，将模拟结果与实验结果进行了比较，同时分析了参数模拟值与理论值之间的误差，验证了该方法的准确性。针对影响隔振器工作性能的激振频率、幅值因素进行了研究，揭示了激振频率、幅值对隔振器隔振性能的影响规律，为隔振器的优化设计提供了科学依据。
Abstract：Aiming at the problem that the quasi-zero stiffness isolator is difficult to achieve better convergence in the finite element situlation process due to its complex structure, this paper uses the multi-body analysis function of ABAQUS sofeware to solve the simplified simulation and convergence problems in the modeling and analysis process of QZS vibration isolators, forms a finite element simulation method for the performance research. The simulation results are compared with the experimental results, then the error between the simulated and theoretical values of the parameters is analyzed, which verifies the accuracy of the method. Research on the excitation frequency and amplitude that affect the performance of vibration isolators reveals the the influence law of excitation frequency and amplitude on vibration isolation performance. The above content provides a scientific basis for the optimal design of vibration isolators.
