根据实际工作需求,设计出工作频率为28 k Hz、过渡段为指数型的复合变幅杆。利用小端圆柱转换圆环斜槽结构来实现单激励纵-扭复合振动,并通过仿真分析讨论了复合变幅杆大端长度、斜槽倾斜角度、斜槽宽度、斜槽长度等结构参数对共振频率的影响规律。在此基础上优化结构并进行试验研究,结果表明该变幅杆实现了纵-扭复合振动并基本满足实际工作需求。
According to the actual work requirements, the design of the working frequency of 28 k Hz, the transition section of the composite exponential horn. The single-excited longitudinal-torsional composite vibration is realized by using the small-end cylindrical conversion circular chute structure. The structural parameters such as the length of the large end of the composite horn, the inclined angle of the inclined groove, the width of the inclined groove and the length of the inclined groove are discussed through the simulation analysis The influence of resonance frequency. Based on this, the structure is optimized and the experimental study is conducted. The results show that this horn achieves the longitudinal-torsional composite vibration and basically meets the actual working requirements.
