Abstract.

The paper considers rubber vibration isolators with a complex shape of free surface designed as elastic links for machines that are experiencing long-term stationary cyclic loads. Such surface shape of vibration isolators allows to realize a very important feature – a weak stiffness in the direction of the force applied and heavy load capacity. Static characteristics and temperature distribution of dissipative heating under cyclic compression are defined experimentally for specific elements such as AR and VR. Formulas for calculating stiffness parameters of the elements under compression and shear deformations are presented with taking into account ratio of conditional and true values of Young’s modulus and shear modulus.

Keywords:

shock absorber of complex shape, force-sediment dependence, apparent elastic modulus, true elastic modulus
