    Abstract
  • Based on the conventional calculation method of dynamic stiffness for rubber ring isolator, a new calculation method is presented by simulating principal components of the isolator as a whole. Firstly, a finite element model of rubber ring isolator is established including metal and rubber parts. Then, sinusoidal excitations with different fre- quencies are exerted on isolator ring according to its actual force condition. As a result, dynamic stiffness in different direction is obtained by simulation. By comparing with static stiffness of isolator and dynamic stiffness of rubber, some variation rules of dynamic stiffness of the isolator are observed, which may benefit vibration analysis of engine and simplification of rubber ring isolator.
