摘要/Abstract

摘要： 采用SYSWELD软件对A-100钢复杂连接件进行了有限元建模,对其在无刚性约束条件下淬火过程中温度场和形变进行了模拟仿真,并对模拟结果进行了试验验证。温度场结果表明:冷却0.13 s时温度分布均匀,零件表面温度在820 ℃左右;冷却5~60 s时,零件表面的温度分布极为不均匀,零件头部型腔的棱角处温度较低,而位于底部的支臂与翼面连接处温度较高;而当冷却时间延长至160 s左右时,零件的整体温度已降至60 ℃以下。形变场结果表明:当冷却时间为0.5~10 s时,翼面远离加强筋部位产生较大淬火畸变,顶端棱角处畸变达3 mm;冷却到600 s时,最大畸变量减小至0.65 mm。根据畸变模拟结果设计了专用淬火工装,校形率达到70%左右。

Abstract: Finite element model of A-100 steel complex connector was established to simulate the temperature field and quenching distortion in the absence of rigid constraints during the quenching process by using SYSWELD software, and the simulation results were verified by experiments. The temperature field results show that when cooling for 0.13 s, the temperature is evenly distributed and the surface temperature of the parts is around 820 ℃; while when cooling for 5-60 s, the temperature distribution on the surface of the part is extremely uneven, the temperature at the corners of the head cavity of the part is relatively low, and the temperature at the connection between the arm and the wing surface at the bottom is relatively high. When the cooling time is extended to about 160 s, the overall temperature of the parts has dropped to below 60 ℃. The distortion results show that when the cooling time is 0.5-10 s, the wing surface far away from the reinforcing rib produces quenching distortion and the distortion at the top edges and corners reaches 3 mm. When cooling for 600 s, the maximum distortion decreases to 0.65 mm. According to the distortion simulation results, a special quenching tool is designed, and the distortion correction rate can reach about 70%.
