Abstract

Results are presented from an experimental study of the processes of thermal relaxation in viscoelastic media under the action of ultrasonic waves. Silagerm 5020 1/3 polyurethane is selected as a model sample of a viscoelastic medium. A plane ultrasonic transducer with a cooled surface is used to heat the samples. Temporal dependences of the temperature distribution at different depths of a polyurethane sample are obtained and interpreted.

暴露于超声波的粘弹性介质中的热弛豫过程

摘要

结果来自于在超声波作用下粘弹性介质中热松弛过程的实验研究。选择Silagerm 5020 1/3聚氨酯作为粘弹性介质的模型样品。具有冷却表面的平面超声换能器用于加热样品。获得并解释了聚氨酯样品不同深度处温度分布的时间依赖性。
