Influence of Thermal Environment on Simulation State of Abrasion Tester and Compensation Method

Abstract

Abrasive testing machine can effectively evaluate the wearability of sealed coatings for aircraft engines. High temperature, high speed and harsh working conditions have brought difficulties to the development of testing machines, At the same time, it brings motion error to the test machine feed system. This paper analyzes the error brought by the high temperature environment to the feeding system of the testing machine, and proposes an evaluation and compensation method. Through experimental verification, the method can effectively eliminate the experimental error caused by temperature and evaluate the wearability of the seal coating. Laid the foundation of research and provided accurate test evaluation conditions.
