Paper Title:
Modal Analysis of Externally Pressurized Air Bearing Workbench Based on Spring-Mass System Method
  Abstract

The stiffness of externally pressurized air bearing is nonlinear, so it is difficult for nonlinear modeling and modal analysis with Finite Element Modal Analysis(FEMA). In this paper, the spring-mass system method which use linear springs in place of nonlinear air bearing has been developed to make FEMA of externally pressurized air bearing workbench more easier and faster. The actual modes of the workbench have also been attained with Experimental Modal Analysis (EMA). The results of EMA have a good agreement with FEAM results ,which verifies the feasibility of spring-mass system method.
