- Abstract
In bearings research, noise is an important evaluation index for mechanical property, in particular in muting machinery technology. Environmental pollution caused by bearing noise has always been the focus in bearing industry. In this paper we consider: i) sliding incentive of the rolling element bearing, and ii) its own variable stiffness incentive, to: i) accomplish the vibration coupling between the bearing and bearing seat, and ii) the coupling between bearing vibration and noise. This is achieved by means of combination of: i) kinetic model, ii) FEM method and iii) BEM method. The aim is to: i) build a perfect coupled vibro-acoustic model of the bearing, and ii) compare the test results and numerical simulation results of the bearing vibration velocity in order to verify the feasibility of the simulation model. Then the noise is calculated by the simulation model. Based on this, the improved design was carried out for low-noise rolling bearings, and the feasibility of the improvement program was verified by means of simulation.
