动力吸振器中橡胶衬套径向刚度分析
Analysis of radial stiffness of rubber bush used in dynamic vibration absorber
摘要
Abstract
In order to study the influence of the structural parameters of the rubber bush on its radial stiffness,the constitutive relation of rubber materiel is used to obtain the calculation formula of the dimensionless radial stiffness coefficient.The obtained theoretical result is consistent with previous research results in both long rubber bushes and short rubber bushes.The simulation case was conducted by thefinite element method to verify the correctness of the theory.The axial compression experiment was conducted to obtain the parameters needed in the simulation.The result shows that the percentage difference between the theoretical result and the simulation one is only 2.75％.A series of simulations were conducted to compare with previous work,and the largest magnitude of the percentage difference is only about 5％.Finally,the radial stiffness experiment was conducted by using a dynamic vibration absorber,and the influence of the structural parameters of the rubber bush on its radial stiffness is obtained.The result shows that the radial stiffness of the rubber bush increases with the increase in the length and the inner radius,but decreases with the increase in the outer radius.关键词
