Abstract

The invention discloses a measurement device and method for a simulation air compressor in a working state. The measurement device comprises a bottom plate, and the bottom plate is provided with an end part assembly module, a first bearing mechanism which is used for bearing a first end journal of an air compressor rotor assembly from the bottom of the air compressor rotor assembly, and a second bearing mechanism which is used for bearing a second end journal of the air compressor rotor assembly from the bottom of the air compressor rotor assembly, and carrying out the axial and / or radial finetuning and control of a bearing position. A measurement mechanism and a positioning plate are disposed between the first bearing mechanism and the second bearing mechanism, wherein the measurement mechanism is corresponding to centrifugal impellers of the air compressor rotor assembly and the parts between the adjacent centrifugal impellers and is used for measuring the jump values of blade tipsof the centrifugal impellers, the wheel hubs of the centrifugal impellers and an air compressor rotor shaft in a rotating process, and the positioning plate is attached to a reference surface of the air compressor rotor assembly so as to form a measurement reference of the measurement mechanism.

Description

technical field [0001] The invention relates to the technical field of aero-engine simulation measurement, in particular to a measurement device for simulating the working state of an air compressor. In addition, the present invention also relates to a measurement method based on the simulated compressor working state, which includes the above-mentioned measuring device under the simulated compressor working state. Background technique [0002] The compressor components of a new turboshaft engine are composed of a compressor rotor assembly and a compressor axial casing assembly. The rotor assembly is a single-rotor structure with five axial flow stages and one centrifugal stage. The compressor axial flow casing assembly is composed of a compressor casing and stator blades. The stator blades are non-rotatable parts of the compressor. The stator blades of the compressor casing assembly and the compressor rotor blades are arranged in a staggered manner to form an airflow chann...
