This test bed has an independent oil supply lubrication system, adopts advanced field bus technology, realizes the automation of equipment operation, and the system is stable and reliable, which provides a strong support for enhancing the independent research and innovation ability of oil film bearing in our country. In order to respond to the strategic policy of green energy saving in our country and to adapt to the new situation of continuous innovation of production technology, the scientific nature and advanced nature of oil film bearing test research should also keep pace with the times. In this paper, the energy flow analysis of the whole test system is carried out, the energy efficiency of the test system is scientifically evaluated, and the improved method is put forward, at the same time, the material circulation of the test system is qualitatively analyzed. On this basis, the material flow in the test system is described quantitatively, the speed control precision of DC motor is improved by using advanced control method, the remote monitoring system is designed, and the remote laboratory platform is established. The intelligence level of the test bed is improved. The main research contents are as follows: first, the energy flow analysis of the test-bed system is carried out. The energy balance model of the test system is established, the energy utilization of each link in the test system is calculated, the energy efficiency of each subsystem is obtained, and the energy efficiency of the whole test system is obtained. Based on the analysis of the factors affecting the energy utilization of the test system, the method of improving the test system is put forward. Secondly, the material flow analysis of the test bed system is carried out. This paper qualitatively analyzes the circulation of each substance in the running process of the test bed, calculates and analyzes the material loss of the test bed, and obtains the consumption intensity and the material productivity of each substance. The measures to improve the material productivity of the test bench are put forward. Thirdly, the motor speed control system is optimized. The fuzzy pid control system is designed based on the pid control system of the motor speed of the test-bed. The simulation software Simulink is used to compare and analyze the fuzzy pid control system. The application of the fuzzy pid control system on PLC is realized by using the programming software STEP7. The accuracy of the speed control system is improved and the operating performance of the test bed is optimized. Fourthly, the remote monitoring system of the test bed is designed by using WinCC component function. The remote client access and mobile terminal equipment access are realized, and the remote laboratory operating platform based on the test bed is developed through the design of the website. The intelligence level of the test bench is improved.
