摘　　要：利用波在粘弹性体中能量的转换机理，给出了超声波焊接聚乙烯时在接头处能量的转换形式，同时计算了接头处的温度分布。试验结果表明，所建立的能量模型及温度计算结果是合理的，这有助于建立合理的焊接工艺规范。The transforming model of energy in the joint of ultrasonic welding for polythene is given in this paper and temperature distribution in the joint is calculatid by utilising the transforming mechanism of energy transmission of wave in the viscoelastic body Experiment re-sults show that energy transmission model and temperature calculation results are reasonable and helpful to determine correct welding specification.
