The invention belongs to the technical field of pipeline test platforms, and in particular relates to a test platform for static and dynamic mechanical performance testing of an aero-engine L-shaped pipeline, comprising a tensile structure, a dynamic loading structure, a sealing structure, a multi-point vibration structure, and a temperature gradient Heating device, measuring mechanism, supporting platform and safety protection structure. Each part can cooperate with each other to simulate complex working conditions, and obtain the properties under complex working conditions. The test platform provided by the invention has a wide application range and can be used for L-shaped pipeline tests of different sizes; the test conditions can be controlled, and the external influence is small; the simultaneous performance of various performance tests has a good effect of simulating the actual environment, especially Dynamic load environment; simple structure and easy maintenance.
Description
technical field [0001] The invention belongs to the technical field of pipeline test platforms, and in particular relates to a test platform for testing the static and dynamic mechanical properties of L-shaped pipelines of aeroengines. Background technique [0002] There are many types and complex configurations of aero-engine pipelines, which usually play the role of transporting fuel for the engine and providing oil pressure. Among them, the "L"-shaped piping of aero-engines is widely used because of its convenient direction adjustment, easy support and optimized layout. Then, due to the complex and changeable working conditions of aero-engines, for example, harsh vibration, shock and other environments not only easily lead to excessive vibration and large deformation of various pipelines, but also easily cause problems such as crack damage and fatigue damage. Also can cause fuel leakage, cause the paralysis of whole engine power performance, and then lead to major safety...
