Abstract

Abstract This work aims to analyze the wear properties of the hybrid aluminum metal matrix composites (HAMMCs) using finite element analysis (FEA). A dry sliding linear reciprocating wear mechanism is analyzed using ANSYS 19.1. Aluminum 7075 alloy and HAMMC reinforced with ZrB 2 (1, 3, and 5 wt.%) and fly ash (2 wt.%) is taken as sample material. A steel ball (EN 52100) is utilized as a counterpart in the dry sliding wear properties study. The deformation of the steel ball during the wear process is assumed to be negligible. Under various circumstances, a 3D point-to-surface connection is built to analyze the dry sliding wear process. The wear depth, contact pressure, and wear volume are analyzed using FEA. The analytical results are compared with the experimental results with the help of ANSYS to analyze the process parameters. The ANOVA analysis is employed for optimization, which exhibits that the load had the most significant impact on the material’s wear rate, followed by the material’s composition and temperature. The wear depth, wear rate, and contact pressure at optimum input parameters for the HAMMCs are 0.47 μ m, 11.31 × 10 −6 mm 3 Nm −1 , and 0.33 MPa, respectively. The Simulated results support the experimental results, and the average error is 9.82%.

混合铝金属基复合材料线性往复磨损机理的有限元数值模拟

摘要采用有限元分析方法对混合铝金属基复合材料(HAMMCs)的磨损性能进行了研究。利用ANSYS 19.1对干滑动直线往复磨损机构进行了分析。以ZrB 2(1、3、5 wt.%)和粉煤灰(2 wt.%)增强的7075铝合金和HAMMC为试样材料。在干滑动磨损性能研究中，使用钢球(EN 52100)作为对应物。假定钢球在磨损过程中的变形可以忽略不计。在各种情况下，建立三维点对面连接来分析干滑动磨损过程。采用有限元分析方法对磨损深度、接触压力和磨损量进行了分析。将分析结果与实验结果进行对比，利用ANSYS软件对工艺参数进行分析。采用方差分析进行优化，结果表明，载荷对材料磨损率的影响最为显著，其次是材料成分和温度。在最佳输入参数下，hammc的磨损深度为0.47 μ m，磨损率为11.31 × 10−6 mm 3 Nm−1，接触压力为0.33 MPa。仿真结果与实验结果基本一致，平均误差为9.82%。
