Intelligent Management and Control Technology for Hydraulic Loading System of Altitude Simulation Test Facility Based on Lightweight BIM

To enable the intelligent and efficient operation of hydraulic loading tests during an aeroengine altitude simulation test, and to improve and optimize its test platform, an intelligent management and control technology of the hydraulic loading system test based on lightweight BIM was proposed. The hardware and software collaborative operation architecture of the hydraulic loading test supporting the management and control platform was established, and the WebGL-based technology of real-time data display on the Web 3D models was proposed to improve the intuitiveness of test monitoring. The designed intelligent management and control platform integrates functions such as test setting and operation, data management, test process analysis, fault diagnosis analysis, etc. The results show that the proposed intelligent management and control technology based on lightweight BIM can make test operators intuitively, conveniently, and efficiently conduct test process management and control, comprehensive data management, and equipment health analysis, improving the intelligence and automation level of the hydraulic loading system of altitude simulation test facility.
