Abstract.

We present calculation algorithm for type VR vibration isolators with internal jumpers to get the nonlinear stiffness characteristics. Determination of the stiffness parameters and dissipative heating under static and dynamic loads is considered. The problem of the thermomechanical behavior of vibration isolator is solved by finite element method: we use isoparametric quadrilateral finite element with quadratic approximation of the displacement fields and temperature.

Keywords:

type VR vibration isolators, stiffness parameters determination, static and dynamic loads, finite elements method
