摘要

利用有限元分析软件ANSYS,仿真了液压缸活塞杆连续驱动摩擦焊接头温度场,并根据仿真参数进行了实验验证。结果表明:焊接初始阶段温度急剧升高,接着升速放缓,最后趋于平衡;依据滑动摩擦机制所建立的热源模型,能够反映生热功率和焊接温度之间的反馈平衡作用,从而使焊接过程始终保持固相。仿真结果与实验结果比较吻合。
        The temperature field of hydraulic cylinder piston rod continuous driven friction welding is simulated by finite element analysis software ANSYS. According to the simulation parameters, the experimental verification is carried out. The results show that the temperature rises sharply at the initial stage of welding, then the speed rises slowly, and finally tends to balance; the heat source model established based on the sliding friction mechanism can reflect the feedback and balance between the heating power and the welding temperature. The simulation results are in good agreement with the experimental results.
