【摘要】 为了优化开缝圆环换能器的设计,采用有限元仿真软件对两种结构的开缝圆环换能器进行计算,再使用多普勒激光测振仪对开缝圆环换能器空气中振幅进行测量,并将仿真与实测结果进行对比。研究结果表明,同尺寸条件下,变截面结构与等截面结构的开缝圆环换能器相比较,谐振频率上升,振幅放大作用明显。更多还原

【Abstract】 In order to optimize the design of slotted ring transducer, finite element simulation software was used to calculate the two structures, and then Doppler laser vibrometer was used to measure the amplitude in the air of slotted ring transducer, and the simulation results were compared with the measured results. The results show that the resonant frequency and amplitude of the slotted ring transducer with variable cross-section increase compared with the slotted ring transducer with constant cross-section structure under the same size condition.更多还原
