摘要: This paper describes the application of geometry optimization method proposed by Hashimoto to design air lubricated thrust bearings used for HDD spindle motors. The is carried out maximize dynamic stiffness films because low a serious problem in actual motor. optimized stiffnesses are obtained changing allowable film thickness, which corresponding tolerance bearings. results show that have comparable oil and it verified theoretically this type bearing can be
