Abstract

The invention discloses a high-temperature internal pressure shear deformation lateral stiffness test system of a pipeline system. Technical difficultiesinequivalent simulation of lateral shear deformation under the working conditions of high temperature and internal pressure of a pipeline structure are overcome, and the influence of tool friction on lateral stiffness by axial elongation ofpipelines is eliminated to a certain extent. The test system can synchronously simulatethe conditions oftemperature, internal pressure and lateral shear deformation and examine structural strength, rigidityand sealing performance, thereby being capable of providing a design basis for various engine related pipeline structures.

Description

technical field [0001] The invention relates to the technical field of ground comprehensive simulation tests, in particular to the high temperature internal pressure shear deformation lateral stiffness of the pipeline system in the high temperature, internal pressure, lateral deformation and other working states of the gas pipeline system of missiles, rockets and other types of aircraft engines Experiment with the test system. Background technique [0002] The pipeline system is an important subsystem of the aircraft engine, which can be divided into different pipeline systems such as transportation, pressurization, and flame exhaust according to its function. Pipelines have different functions, and they are subjected to different thermal and mechanical comprehensive environments. Affected by the comprehensive environment, the pipeline structure will have problems such as reduced strength, weakened sealing performance, and changes in inherent mechanical properties. In sever...
