摘要：Sliding bearings are widely used in various types of rotating machinery due to the development of modern industry. The oil film pressure produced by the sliding bearing has very strong nonlinear characteristics. In order to study the dynamic characteristics of sliding bearing in experiments, in this paper, a sliding bearing test rig is restructured. A special acquisition system is designed to measure the vibration of the journal in sliding bearing. The acquisition system consists of optical fiber displacement sensors, pre-processor, data acquisition device, host computer. Several experiments were carried out by the test rig under different rotational speeds, different eccentric masses, and different bearing loads. The effects of the rotational speed, eccentric mass and bearing load on the dynamic characteristics are analyzed and some conclusions are obtained which is consistent with the theory.
