Study on the Natural Vibrations of the Rubber Bearings

Abstract:

The noise of the rubber bearing is closely related to its vibration characteristics, thereby, the study of the natural vibrations is of an important significance for the safety of the warships. Based on the finite element method, this paper analyzes the effect of the structural parameters and material properties on the natural vibrations of the rubber bearings, the numerical results show that in the low frequencies its vibration modes mainly present the shear deformations in its center of the rubber strip. The influences of the variations in the thickness of the built-in steel bars on the natural frequencies are larger than that in the width, and the variations of rubber materials’ mechanical properties on the natural frequencies are remarkable. Thus, increasing the elastic modulus of rubber material will effectively enlarge the value of the natural frequencies, as well as improve their intensive distribution.
