Abstract

The invention provides a method and device for analyzing contact abrasion of an aviation hydraulic flaring pipe joint. The analysis method comprises the steps of determining the root-mean-square roughness of the contact surface of the aviation hydraulic flaring pipe joint; Simulating a random rough surface conforming to Gaussian distribution according to the root-mean-square roughness; Establishing a finite element model of the random rough surface in contact with a rigid plane; Determining a contact load between the random rough surface and the rigid plane according to the finite element model; And determining the wear amount of the random rough surface according to the contact load. According to the invention, the contact wear can be analyzed under the condition that no test is carried out.

Description

technical field [0001] The present disclosure relates to the technical field of material wear, in particular to an analysis method and device for contact wear of aviation hydraulic flared pipe joints. Background technique [0002] Due to the influence of raw materials and processing factors, the contact surface of aviation hydraulic flared pipe joints has a certain roughness. When vibration occurs, the installed aviation hydraulic flared pipe joints will be worn, which will easily lead to failure of hydraulic pipes, thereby reducing safety and reliability. [0003] At present, people mainly analyze the contact wear through experiments. However, due to the extremely small amount of wear on the contact surface of the aviation hydraulic flared pipe joint, it is difficult to analyze it through experiments. [0004] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosur...
