Durability test structure of stator blade angle adjusting mechanism

Abstract

The invention belongs to the technical field of durability tests of stator blade angle adjusting mechanisms of engines, and particularly relates to a durability test structure of a stator blade angleadjusting mechanism. The durability test structure comprises: a compressor casing; a plurality of elastic pieces which are connected with the compressor casing and distributed in the circumferential direction of the compressor casing; a plurality of rocker arms, wherein one end of each rocker arm is correspondingly connected with one elastic piece; a linkage ring which is arranged on the compressor casing in a sleeving manner and is connected with the other end of each rocker arm; and an actuating cylinder which is arranged on the compressor casing, wherein the piston rod of the actuating cylinder is connected with the linkage ring so as to drive the linkage ring to rotate in the circumferential direction of the compressor casing, and therefore the rocker arms are driven to swing synchronously, and the elastic pieces are deformed.

Description

technical field [0001] The application belongs to the technical field of durability test of an engine stator vane angle adjustment mechanism, and in particular relates to a durability test structure of a stator vane angle adjustment mechanism. Background technique [0002] In order for the compressor in the engine to work stably, it is necessary to adjust the air flow through the compressor according to the actual situation. For this purpose, the angle of each stator blade in the compressor can be adjusted, and the stator blade angle adjustment mechanism can be used to adjust the synchronous rotation of each stator blade to synchronize The rotation angle of each stator vane is changed, so as to realize the adjustment of the air flow flowing through the compressor. [0003] The existing stator blades have an upper journal and a lower journal, and each stator blade is distributed along the circumferential direction between the compressor casing and the inner ring of the stator...

AI Technical Summary

Problems solved by technology

[0006] 1) The durability analysis of the stator blade angle adjustment mechanism is carried out by means of simulation. The durability of the stator blade angle adjustment mechanism obtained by the simulation technology analysis usually has a certain deviation from the actual situation, and sometimes there is even a large deviation, which is difficult to provide The design and improvement of the stator vane angle adjustment mechanism provide reliable support;

[0007] 2) To verify the durability of the stator blade angle adjustment mechanism through the engine test, it needs to run the entire engine, which consumes a lot of manpower, material resources, and financial resources. Design of the blade angle adjustment mechanism, progress requirements for improvement
