橡胶金属复合低频隔振器的设计及静态特性分析
|
摘要
设计了一种基于压杆大挠度弯曲变形理论的橡胶金属复合准零刚度隔振器,建立了原理模型和有限元模型,得出了静态力学特性。仿真结果表明,复合区域金属骨架厚度是影响负刚度特性的主要因素,设计的隔振器能够提供良好的低频隔振效果。
A rubber/metal composite quasi-zero stiffness vibration isolator was designed based on the large deflection bending theory of the compression bar,the principle model and finite element model were established,and the static mechanical properties were obtained. The simulation results showed that the thickness of the metal skeleton in the composite region was the main factor affecting the negative stiffness characteristics. The designed vibration isolator could provide good vibration isolation effect in the low frequency range.
