摘要

建立了一个零件尺度的模型

采用收缩体积法模拟预测了激光选区熔化（Selective Laser Melting

SLM）成形AlSi10Mg合金悬臂梁的变形

研究了几何结构、扫描方式以及预热温度对悬臂梁残余变形的影响。结果表明

模拟计算的翘曲方向和变形趋势与试验测量结果相符;悬臂梁的厚度越大其刚度越大

抵御变形的能力越强;提高预热温度可以有效减小零件的变形。

Abstract

A model of part scale was established to predict the deformation of SLM-formed AlSi10 Mg alloy cantilever beam by shrinkage volume method.The influence of geometry

scanning patterns and preheating temperatures on the residual distortion of the cantilever was analyzed.The results reveal that the warping direction and deformation trend of the simulated calculation are well in agreement with the experimental ones.The greater the thickness of the cantilever

the greater its rigidity and the stronger the ability to resist deformation.The increase of preheating temperature can reduce effectively the deformation of the parts.
