Description

technical field [0001] The invention relates to a reliability testing device and a testing method of an engine piston telemetry system, belonging to the field of engine testing. Background technique [0002] With the proposal of the "dual carbon" goal, the engine has been rapidly developed in the direction of more efficient performance, stronger power, and more compact structure. With the rapid increase in power density, the highly enhanced engine is prone to thermal failure caused by excessive thermal load. Therefore, it is extremely important to test and control the engine. As the core component of the engine, the piston is subjected to the worst working conditions of the whole machine. The reasonable regulation of its temperature will directly affect the reliable operation of the engine. In the process of independent research and development of the engine, CAE and other methods are used to carry out the preliminary design, but the temperature field, stress and strain and...

AI Technical Summary

Problems solved by technology

At present, due to the wide variety of engine piston specifications and types, the piston telemetry system has not yet formed a stable and highly applicable structural form and installation standard

The detection of dynamic and unsteady working conditions often relies on the actual machine test, and the real machine test often has a long preparation period, which takes up a lot of resources and manpower investment, and the untested telemetry piston directly tests the whole machine, which will greatly increase the piston telemetry. The risk of system failure, and the falling off of accessories will also affect the normal operation of the engine

At the same time, the previous temperature calibration is usually carried out under static and low temperature conditions. The actual operating environment may have a certain impact on the accuracy of the test system, and further calibration needs to be carried out under close to actual working conditions.
