摘要: 目前利用声场的虚拟扫描数据进行可视化研究以及通过可视化数据进行参数测量的研究较少。基于MATLAB软件通过APP Designer开发出新的超声声场可视化软件，设计出声轴线上的声场分布仿真和声轴横截面上的声压仿真两类仿真试验，验证了所开发仿真软件在同一介质中换能器频率不同和半径不同情况下的声场变化，以及不同介质中使用固定频率和半径的换能器时的声场变化。试验结果表明，开发的软件在超声声场仿真模拟方面具有可靠性。Abstract: At present, there are few researches on the visualization using the virtual scanning data of sound field and using the visualized data to make the measurements. A visualization software of ultrasonic field based on MATLAB through APP Designer was developed in this paper. Two kinds of simulation experiments were designed:the simulation of sound field distribution on the sound axis and the simulation of sound pressure on the cross section of the sound axis. It is verified that the sound field changes with different frequencies and radius of the transducer in the same medium, and it also changes in different media while using fixed frequency and radius transducer in different media. The experimental results show that the software developed in this paper was reliable in the simulation of ultrasonic field.
