Air-bearing is a core component of air-bearing rotary stage. The weakness that the air-bearing has the low load capacity and stiffness has been concerned about by domestic and foreign scholars. So how to improve the load capacity and stiffness has become a serious problem. In order to improve the load capacity and stiffness of the air-bearing rotary stage  in this paper  we improved structure of Zhang Wenjie and others' high-precision direct-drive air-bearing rotary stage. The gas film of air-bearing has been meshed by GAMBIT software  and we use FLUENT software to obtain the carrying capacity features of the gas film. Finally  the structural static force of the precision air-bearing rotary stage will be analyzed by ANSYS software. The analysis results show that: the structural design of the precision air-bearing rotary stage is reasonable  and this structure can provide a larger range of loads. Even in heavy load conditions  a larger deformation will not occur any more. It has a good practical value  and also can be widely used in high precision equipments. (2012) Trans Tech Publications.

This article is the study of alternating stress of flexible wheel in harmonic gear drive system. Firstly  then  Finally  according to elasticity theory to theoretically analyze flexible wheel stress  based on the basic principle of sub-structure modal synthesis method  based on the dynamics simulation  use the software of UG  to analyze the alternating stress simulation results of flexible wheel and compare theoretical results and simulation results to come conclusion. The results show that: altering stress simulation results of flexible wheel are coincident with theoretical simulation results  PATRAN and ADAMS to carry out co-simulation  have a deeper understand the stress change trend in the drive process of flexible wheel  lay a foundation for further carrying out dynamics simulation of harmonic gear drive system.
