Problems solved by technology

There are many factors that affect the thermal deformation of the disk-shaft connection rotor system. Although many scholars have used the finite element method to conduct quantitative analysis on it, these analyzes are carried out on the basis of simplifying the heat source and the disk-shaft connection structure, so it is difficult Accurate control of thermal characteristics, while using finite element method to analyze the thermal deformation of the spindle system is difficult to achieve accuracy, compared with finite element modeling, experimental method can analyze more accurately and get more accurate results

Abstract

The invention belongs to the field of aero-engine disc-shaft connection rotor system thermal effect analysis and thermal deformation measurement, and relates to a disc-shaft connection rotor system thermal analysis test bench and a thermal deformation measurement method. The test bench is mainly composed of an electric drive and control system, an ignition system, a heat insulation system, a nonlinear support-rotor system, a test sensing system and a base. The heating temperature of a disc-shaft connection rotor system can be accurately controlled by an igniter. By adjusting the gas valve of the igniter, the firepower of the igniter can be controlled, and the disc-shaft connection rotor system can be heated within different temperature ranges. The thermal deformation of a disc-shaft connection rotor system in an environment with uniform temperature distribution can be measured, and the thermal deformation in an environment with non-uniform temperature distribution and the thermal deformation under a variable speed condition can be measured.
