摘要
应用ANSYS软件对汽车保险杠防撞梁进行淬火数值模拟,分析了淬火过程中工件的温度场、变形场和应力场的动态变化情况,在淬火40 s和60 s两个不同时间对工件的淬火性能进行了对比。结果表明:用常温静态水作为淬火介质对铝合金防撞梁的变形和应力的影响不大,在淬火40 s时虽然工件的温度几乎达到介质温度,但此时并未淬透,而淬火60 s时工件已淬透,满足该模型实际应用的性能要求。
In this paper, with the help of large general commercial finite element software ANSYS, the quenching numerical simulation of ear bumper buffer beam was conducted. The dynamic change condition of the temperature field, stress field and strain field in the quenching process were mainly analyzed. Also, in the two different time of 40 s and 60 s, the quenching performance of buffer beam were compared. Simulation results showed that the impact to the deformation and stress for the alumialloy buffer beam quenching was slight when room temperature static water was used as the medium. Although the temperature could almost reach the medium temperature in quenching 40 s, the buffer beam was actually not quenched thoroughly. On the contrary, in 60 s the buffer beam could be quenched thoroughly and meet the model' s performance requirements in practical application.In conclusion, using numerical simulation method can provide a set of economic and efficient approaches for the online heat treatment process.
