Brake strength test bed

Abstract

The invention relates to a brake strength test bed, and belongs to the technical field of aerospace engine testing. The test bed is composed of a mechanical part, a hydraulic system, an actuator assembly, a control system, a test system and a monitoring system. The mechanical part comprises a force bearing platform, a bearing stand column and a bearing cross beam. The actuator assembly is mountedon the bearing cross beam; the hydraulic system comprises a high-pressure oil source, a hydraulic substation, an oil distribution module and a matched pipeline. The oil distribution module is connected with the actuator assembly; the control system comprises a hydraulic control system and a multi-channel loading control system; the test system is in modular design, can be infinitely expanded and supports access of sensors of various signal types; and the monitoring system is divided into a video monitoring subsystem and a field communication subsystem which are respectively used for monitoringoperation conditions of equipment in a test room and a hydraulic oil pump room in real time to realize bidirectional wired communication between workshop control rooms. The mechanical part is reliable and adjustable, test functions are complete, and real-time monitoring control and alarm can be realized.

Description

technical field [0001] The invention belongs to the technical field of aerospace engine testing, and more specifically relates to a brake strength test bench. Background technique [0002] With the continuous development of my country's aviation technology, my country's aviation industry has made great progress. However, when it comes to engine technology, it has always been a weakness and has received technical blockade from abroad. The engine lock is one of the important basic parts of the aircraft engine. Its performance has a fatal impact on the running quality of the engine. Therefore, it is particularly important to test the performance of the aircraft engine lock. [0003] Since the brakes of aircraft engines are usually thin-walled annular parts, and the cavities are distributed on different levels, it is required to test under different pressures. It is extremely difficult to ensure the smooth progress of the strength test. In the existing technology, the strength ...

Problems solved by technology

However, the application only discloses components such as the mechanical servo cylinder, and does not optimize the design of the bearing column, beam, etc., and lacks an overall grasp of the entire test bench except for the mechanical components.
