摘要
超声波塑料焊接的温度场是研究其焊接机理的重要方面。但是由于超声波塑料焊接具有时间短、局部焊接区域封闭等特点,使得对焊接温度场的研究很困难。采用有限元的方法,对超声波塑料焊接过程中的温度场进行了数值模拟,并建立了具有高响应频率、实时测量、数据存储功能的先进测量系统。模拟结果和实际测量结果相近,说明有限元模型合理。
The temperature field of welding is an important factor to study ultrasonic plastic welding which is an economical and efficient plastic bonding method. But it is difficult to do the research work in that the welding time is so short and the local welding field is close. This paper introduces the finite element analysis（FEA） method to simulate the temperature field and also introduces an advanced measurement system with high response frequency, real-time measurement and data storage features. Using the measurement system, the temperature field can be measured. The results of simulation and measurement are close,so the FEA model was reasonable.
