基于ABAQUS的陶瓷颗粒增强铝基复合材料切削特性仿真分析

Simulation Analysis of Cutting Characteristics of Ceramic Particle Reinforced Aluminum Matrix Composites Based on ABAQUS

摘要: 陶瓷颗粒增强铝基复合材料是一种重要的结构材料，因其具有优异的力学性能、高温稳定性和良好的耐蚀性等特点，被广泛应用于航空、汽车、船舶、电子等领域。本文利用Digimat建立了不同增强颗粒(AL₂O₃、SiC、TiC)下的铝基复合材料并通过ABAQUS仿真分析了切削速度和切削深度对切削力和切削温度的影响机制。研究结果表明，陶瓷颗粒增强铝基复合材料的切削行为受多种因素共同影响。首先，在相同切削条件下，TiC增强颗粒的切削力和切削温度最大，SiC次之，AL₂O₃最小，其次，随着切削速度和切削深度的增加，切削力和切削温度逐渐增大，但切削深度主要影响切削速度，切削速度主要影响切削温度。综合而言，本研究为理解不同增强颗粒下的陶瓷颗粒增强铝基复合材料在切削过程中的力学和热学特性提供了重要参考。

Abstract: Ceramic particle reinforced aluminum matrix composite is an important structural material. Because of its excellent mechanical properties, high temperature stability and good corrosion resistance, it is widely used in aviation, automobiles, ships, electronics and other fields. In this paper, aluminum matrix composites with different reinforcement particles (AL₂O₃, SiC, TiC) were established by Digimat, and the complex influence mechanism of cutting speed and cutting depth on cutting force and cutting temperature was analyzed by ABAQUS simulation. The results show that the cutting behavior of ceramic particle reinforced aluminum matrix composites is affected by many factors. First of all, under the same cutting conditions, the cutting force and cutting temperature of TiC reinforced particles are the largest, followed by SiC and AL₂O₃, and secondly, with the increase of cutting speed and cutting depth, the cutting force and cutting temperature gradually increase, but the cutting depth mainly affects the cutting speed, and the cutting speed mainly affects the cutting temperature. In summary, this study provides an important reference for understanding the mechanical and thermal properties of ceramic particle reinforced aluminum matrix composites with different reinforcement particles in the cutting process.
