摘　　要：基于Procast有限元软件为研究工具,研究了铝合金流体在铸型中的自由流动和速度分布、温度分布以及铸造缺陷的分布,并以飞机零部件中的踏板托架支架部件为研究对象进行铸造缺陷分析及工艺优化。结果表明,经过工艺优化后的铝合金薄壁件,其缺陷率明显降低,力学性能得到改善。The free flow and velocity distribution, temperature distribution and the prediction of defect distribution of aluminum alloy fluid in casting mould were studied based on Procast finite element software. Taking the, pedal bracket stand parts of airplane parts as research object, the analysis of casting defects and the optimization of casing process were conducted. The results show that the defect rate of aluminum alloy thin-walled castings decreases and the mechanical properties improve after process optimization.
