摘要

飞机起落架套筒等裸露部件因长期暴露在高流体速度和高颗粒浓度的环境中，易受到环境中坚硬砂石颗粒的冲蚀磨损。为了探究该过程对300M 钢造成的影响，通过气动喷砂设备模拟实际工况，并用ABAQUS/Explicit 基于Johnson-Cook 损伤演化模型建立多粒子冲蚀靶材的有限元仿真模型。使用X 射线衍射仪及激光共聚焦显微镜观测300M 钢形貌特征，通过试验与仿真相结合的方法分析不同环境因素下砂石冲蚀磨损量，并提出适用于300M 钢的侵蚀速率模型，实现对冲蚀磨损过程的定量分析。结果表明:相比小尺寸砂粒(20 目)，大尺寸砂粒(60 目)冲蚀磨损造成表面粗糙度平均提高14.29%，最大冲蚀坑平均尺寸增大23.08%。随冲蚀角度与冲蚀速度的增加，20 目、60 目砂粒表面粗糙度呈现先增大后减小的趋势，且在30°时取得表面粗糙度的最大值，这一规律与形貌起伏相对应；当冲蚀角度固定为30°时，随冲蚀压力的增加(0.3～0.5 MPa)，20 目与60 目砂粒造成的冲蚀磨损量整体增幅区间分别为6%～8%、4%～5%。

Abstract

Exposed components such as aircraft landing gear sleeves are prone to erosion wear from hard sand and gravel particles due to prolonged exposure to high fluid velocities and particle-concentrated environments.In order to explore the influence of this process on 300M steel,the actual working conditions were simulated by pneumatic sandblasting equipment, and the finite element simulation model of the multi-particle erosion target material based on the Johnson-Cook damage evolution model was established by ABAQUS/Explicit.In addition, the morphological characteristics of 300M steel were observed using X-ray diffractometer and laser confocal microscope.The erosion and wear amounts of sand and gravel under different environmental factors were analyzed through the combination of experiments and simulations, and an erosion rate model suitable for 300M steel was proposed to achieve quantitative analysis of the counter-erosion and wear process.Results showed that compared to fine sand particles (20 mesh), coarse sand particles (60 mesh) increased the average surface roughness by 14.29%and enlarged the average maximum erosion pit size by 23.08%.With the increase of the erosion angle and erosion speed, the surface roughness of 20 mesh and 60 mesh sand grains exhibited a trend of first increasing and then decreasing, and the maximum surface roughness was achieved at 30°,which correlated with morphological fluctuations.When the erosion angle was fixed at 30°, with the increase of erosion pressure (0.3～0.5 MPa), the overall increase ranges of erosion wear caused by 20 mesh and 60 mesh sand particles were 6%～8%and 4%～5%, respectively.
