The simulation on rubber shock absorber of machine tool was studied.The simple material model of rubber was obtained by through the finite element analysis software ABAQUS.The compression speed and chiggate.com the hardness of rubber material were considered to obtain the deformation law of rubber shock absorber.The location of fatigue were confirmed from the simulation results.
The results shown that the fatigue position is distributed in the corner of shock absorber.The degree of deformation is increased with increasing of compress speed, and the hardness of rubber material is proportional equi-jec 7 to deformation.
