摘要:

采用Deform-3D有限元软件及等温模锻试验对2024铝合金航空座椅支承零件的成形过程进行了模拟与试验研究,并且分别对等温模锻件和热轧板机加工零件的组织和性能进行了对比研究。结果表明,在420 ℃、锻压速度为1.5 mm·s-1、保压时间为1.5~2 min的锻造工艺参数条件下,2024铝合金航空座椅支承零件锻造成形的最大锻压力为12700 kN,锻件成形金属流动顺利。在本文的工艺条件下试制锻造了多件2024铝合金航空座椅支承件,测试分析结果表明,通过等温模锻制造的航空座椅支承零件较热轧板机加工零件强度提高11.4%,最高的强度为508 MPa,且不同方向力学性能的差异小于3%。

The forming process of aviation seat supporting parts for aluminum alloy 2024 was simulated and tested by Deform-3D finite element software and isothermal mould forging test respectively. Furthermore,the microstructure and mechanical properties of isothermal mould forging and machined parts of hot rolled plate were studied comparatively. The results show that under the condition of temperature of 420 ℃, forging speed of 1.5 mm·s-1 and pressure holding time of 1.5-2 min, the highest forging force is up to 12700 kN, and the metal flows smoothly on the forging mould. Several pieces of forged aluminum alloy 2024 aviation seats supporting parts are produced under the above-mentioned condition. Test and analysis results show that its strength increases about 12% and achieves 508 MPa compared with the machined parts, and the differences among the mechanical properties of different directions are less than 3%.
