Abstract:
The oil film thickness during the work of the machine tool is affected by the load. It is necessary to ensure the accuracy of the guide rail that the thickness of the oil film is maintained in a stable state. The main objective of the present article is to detect the size of the oil film thickness during the working process of the machine tool in real time and simulate the changing cutting force. The mechanical structure of the test bench was designed. The electro-hydraulic servo sys-tem schematic was designed and the hydrostatic guide pressure control scheme was determined, the test bench electro-hydraulic servo control system model-ing was completed. MATLAB was used to build the simulation model and carry out the corresponding sim-ulation analysis. The self-anti-interference controller completed by the PID control of the fast overshoot pavement self-anti-interference control. To verify the method of this paper, the liquid hydrostatic guide test bench was set up and the corresponding testing exper-iments were conducted. The simulation and experi-ments showed that: under the self-anti-interference control environment, the performance of the test bench electro-hydraulic servo control system became better and the oil film thickness tends to be stable.
