【摘要】：采用ANSYS和LS-DYNA仿真分析超声振动聚合物界面摩擦生热过程,主要分析超声振幅、超声频率和摩擦因数对界面摩擦生热速率的影响规律。研究结果表明:界面摩擦生热能使聚合物温度升高,且生热是瞬态过程,超声振动作用时间0.164 45s,聚合物界面局部温度能升高到160.7℃,生热速率达到855.57℃/s。界面摩擦生热速率随着超声振幅、超声频率和摩擦因数的增加而增大,超声频率对聚合物界面摩擦生热速率的影响更显著。
[Abstract]:ANSYS and LS-DYNA were used to simulate and analyze the interfacial friction heat generation process of ultrasonic vibrating polymers. The effects of ultrasonic amplitude, ultrasonic frequency and friction coefficient on the interfacial friction heat generation rate were mainly analyzed. The results show that the temperature of the polymer is increased by interfacial friction heat generation, and the heat generation is a transient process. The ultrasonic vibration time is 0.164 45s, the local temperature of the polymer interface can rise to 160.7 鈩，
