Research on the Performance of Water Lubricated Bearing when Bad Ship Shafting Alignment Based on ADINA

Abstract

Establish the CSD model of water lubricated rubber bearing's normal working and bad alignment condition by using the finite element software ADINA, analyze the difference of the bearing load and the deformation. And conduct tribology test at shrinkage ratio test-bed, and compare the difference of friction coefficient and vibration at bearing's normal working and the horizontal offset condition. The research results show that: when the water lubricated bearing is in bad alignment condition, the force and the deformation increase locally, and the wear of the bearing and the vibration also increase, which is bad for the bearing capacity , wear resistance, shock absorption and so on.
