摘要

This paper describes the development of the modified resistance network method (RNM) for analyzing the dynamic behaviors of an X-shaped grooved aerostatic bearing with a passive non-linear disk-spring compensator. The Newmark integration method and the modified RNM, which takes into account the equilibrium of the mass flow rate and the squeeze film effect, are used to analyze the time-dependent dynamic behaviors. Results show that after impulse the bearing with a non-linear disk-spring compensator can reduce the system vibration, and the table can keep its balance around the equilibrium position.
