Abstract:

In order to realize automatic detection on the gap height, pressure distribution and load capacity of aerostatic gas bearing, a measurement and control system has been designed based on single-chip microcomputer.This system adopts ATmega16L as the core of the platform motion control and data processing.The system realizes polar coordinate positioning and collects the information about load capacity, gas film pressure and gap height combined with the software which is designed to control the steering and speed of stepper motors. the system performs well in human-machine interaction with a LCD and keyboard.The system also can communicate with computer by RS232 and be controlled directly.Comparing the experiment data with simulation,the result shows that,the device and system is feasible.
