摘　　要：运用有限元软件建立了超声波塑料焊接仿真模型,采用多物理场耦合对兆赫频超声塑料焊接过程中的温度场进行了数值模拟,分析了焊接过程中热源的产生、分布以及焊接过程中能量的传递与温度的变化。分析了超声振幅对焊接过程温度的影响,为兆赫频超声焊接振子的设计提供了依据。The simulation model of ultrasonic plastic welding was established by using finite element software, and the temperature field in the welding process of Megasonic welding for plastic was numerically simulated by using multi-physical-coupling field, and the generation and distribution of heat source, energy transfer and temperature change in the welding process were analyzed. The influence of ultrasonic amplitude on welding temperature is analyzed, which provides the necessary basis for the design of Megasonic ultrasonic welding vibrator.
