摘要
针对柱状橡胶减振器在大量级冲击条件下,基于线弹性理论假设带来仿真误差较大的问题,提出了一种利用非线性弹簧阻尼单元的建模方法,给出了该方法的推导过程及冲击刚度曲线的获取方法。通过冲击试验验证了该方法具有很高的计算精度,为减振器的非线性建模技术深入研究奠定了重要基础。
According to linear elastic theory, a large error about cylindrical rubber absorber in the condition of high shock is caused during the simulation analysis. In this paper, a new modeling method based on nonlinear spring-damping element is proposed, The derivation process of the method is described and the way to get the shock stiffness curve of the rubber absorber is intro- duced at the same time. The high precision of the method is verified by many shock experi- ments. This paper has laid the foundation for deeply study on rubber absorber based on nonlinear modeling theory.
