摘要/Abstract

摘要： 建立了30Cr3SiNiMoVA钢大长径比薄壁壳体零件的金属-热-力耦合有限元数值分析模型,通过反传热计算获得了壳体不同位置表面综合换热系数曲线,研究了真空气淬过程中薄壁壳体零件的温度场和组织场的演变规律,并对其畸变行为进行了详细分析。研究表明:同一换热面上的冷速大小为薄壁部位>顶部>台阶部位,且阳面的温度变化更为剧烈;应力演变曲线均出现两个峰值,第一个峰值是由温度差异导致的热应力引起的,第二个峰值是由马氏体转变产生的组织应力引起的;淬火之后,阳面高度增加了2.08 mm,增加幅度为0.082%,阴面高度增加了2.33 mm,增加幅度为0.092%,薄壁位置处外径增加了0.81 mm,增加幅度为0.270%,台阶位置处外径增加了0.57 mm, 增加幅度为0.186%。实测结果与模拟结果相符,误差小于10%。

Abstract: A theoretical framework of metal-thermal-force coupled model of the large diameter ratio thin-walled shell was established,which is made of 30Cr3SiNiMoVA steel. The heat transfer coefficient curve at different positions was calculated through inverse heat transfer method. The distortion behavior was investigated though analyzing the evolution of the temperature field and the structure field during high pressure gas quenching process. The results show that the cooling speed on the same heat exchange surface of the shell is thin-walled position greater than top than step in the middle, and the temperature in the positive side changes more sharply. There are two peak values of the stress curves, the first one is due to the heat stress induced by the temperature, and the second one is due to the structure stress induced by the martensitic transformation. After quenching, the height of the positive side and negative side are increased by 2.08 mm (0.082%) and 2.33 mm (0.092%) respectively, and the outer diameter at the thin wall position and step in the middle are increased by 0.81 mm (0.270%) and 0.57 mm (0.186%), respectively. The measured results are basically in agreement with the simulation, and the error is less than 10%.
