摘要/Abstract

摘要：

本文采用建立理论模型、实验验证以及仿真分析的方法，分析了民机液压软管在含磨损缺陷时的力学性能

变化规律以及失效情况，得出了软管需要重点监控的损伤状态以及建议更换的磨损缺陷深度。基于流固耦

合法，在 ANSYS WORKBENCH 中进行复合管路有限元仿真分析，探究了在不同流体压力下，磨损缺陷深

度、轴向长度对力学性能的影响，给出了不同压力下管路最大总变形和最大等效应变的预测函数关系式，

并建立了损伤管路复合强度模型。由该模型可知，管路在内壁未完全破损前不失效，在磨损深度与壁厚比

为 0.4 时，其力学性能显著下降，此时需重点监控或更换。

Abstract:

Using the approach of theoretical model establishment, experimental verification and simulation analysis, the mechanical performance change rule and failure situation of the hydraulic hose of civil aircraft when containing wear

defects are analyzed in this paper. The damage status of the hose that needs to be key monitored and the wear defect

depth recommend for replacement are obtained. Based on the flow-solid coupling method, a finite element simulation analysis of composite pipeline was conducted in ANSYS WORKBENCH to explore the influence of wear defect

depth and axial length on mechanical performance under different fluid pressures, the prediction function relationship of the maximum total deformation and maximum equivalent strain of pipelines under different pressures are

given, and a composite strength model of damaged pipelines is established. According to the established model, the

pipeline does not fail before the inner wall is completely damaged, and when the wear depth and wall thickness ratio is 0.4, its mechanical performance decrease significantly, when it needs to be key monitored or replaced.

Key words:

hydraulic hose, composite strength, wear defect, single parameter, performance monitoring, residual strength
