| 摘 要： | 驻波和换能器指向性等影响声场均匀性，造成清洗死角，影响清洗效果。采用COMSOL仿真软件建立了单个换能器位于底部的三维模型，通过染色法实验结果验证模型的有效性。研究了换能器同时位于底部和侧面、多排换能器位于底部时的声场，用声压幅值相对标准差来量化均匀性，发现该两种换能器分布方式能够有效优化声场均匀性。通过调节频率研究频率对声场的影响，进一步优化声场均匀性。对声源分布的确定、频率的选择以满足声场均匀化需求有指导意义。

| Abstract: | The Sound field uniformity is affected by standing wave and transducer directivity, which lead to cleaning dead ends and affecting the cleaning effect. A three-dimensional model is established by COMSOL simulation software with a single transducer at the bottom. The validity of the model is verified by the experimental results. The paper mainly studies the sound field distribution uniformity in two cases. One is the transducers place at the bottom and the side meanwhile. Another one is the multi-row transducers place at the bottom. The relative standard deviation of the amplitude of the sound pressure is used to quantify the uniformity. It is found that the two distributions manners can both effectively optimize the sound field uniformity. Sound field uniformity is further optimized by adjusting the frequency of ultrasonic. It is of guiding significance to determine the distribution of sound source and select frequency to meet the demand of homogenization of sound field. |
