摘要
为了解决基于斜槽结构的模式转换型纵扭复合模态超声振动系统存在的扭转分量较小、纵扭转化效率较低的问题,论文对基于周期性扇形孔和斜槽结构的模式转换型纵扭复合模态超声振动系统进行了研究,主要仿真分析了扇形孔结构参数对基于斜槽结构的模式转换型纵扭复合模态超声振动系统谐振频率、扭转振幅、旋转角度和剪切应力的影响规律,并找到使系统获得最佳纵扭转换效率的扇形孔结构参数,且求解出扇形孔结构的引入对系统性能的改善幅度。
In order to solve the problem of small torsional component and low longitudinal and torsional efficiency of mode conversion longitudinal torsional composite mode ultrasonic vibration system based on chute structure,the mode conversion longitudinal torsional composite mode ultrasonic vibration system based on periodic fan-shaped holes and chute structure is studied in this paper.The effects of structural parameters of fan-shaped holes on resonant frequency,torsional amplitude,rotation angle and shear stress of mode conversion longitudinal torsional composite mode ultrasonic vibration system based on chute structure are simulated and analyzed.The fan-shaped hole structure parameters that enable the system to obtain the best longitudinal torsional conversion efficiency are found,and the improvement range of the system performance caused by the introduction of the fan-shaped hole structure is solved.
