It is necessary to use the test platform to simulate the actual working state and working environment of the bearing. Therefore, the research and development of the test system for a certain type of aeroengine spindle bearing is carried out in this paper, which will promote the research level of the aeroengine bearing. The experimental technology of lifting bearing is of great practical significance. According to the performance and test demand of a certain aeroengine spindle bearing, this paper develops a set control and data acquisition, The dual-drive test system of aeroengine spindle bearing is composed of storage and processing. The specific research content is: (1) this paper analyzes the operating condition of aeroengine spindle bearing, and determines the control parameters of aero-engine spindle bearing double-drive test platform. According to the functional requirements of the test platform, the hydraulic loading system, the oil and gas lubrication system, the high and low temperature lubrication system and the measurement and control system are planned. Analysis and calculation of variable parameters, selection of control elements, drawing of the control system schematic diagram, according to the characteristics of the control elements, working mode and wiring requirements, drawing the field construction wiring diagram; At the same time, the key links of the control are simulated and simulated, so that the design of the control system of the test platform is completed. (3) according to the design of the control system of the test platform, Programming control flow. The control program based on Siemens PLCX S7-400 is compiled by using the software of Boto, and the monitoring of temperature, load, rotational speed, pressure and other important control parameters is realized by the upper computer. C # software is used to complete the program of vibration and noise detection system, and the field monitoring is realized by industrial control computer, so as to complete the software development of the control system of the test platform. The control system of the dual-drive test platform for aeroengine spindle bearings studied in this paper can meet the test requirements of aeroengine spindle bearings. At the same time, it can be widely used in the performance test of aeroengine spindle bearings. Through the successful completion of test bench debugging, a large number of test data have been collected, and reliable technical support has been provided for the development of bearing test technology.
