摘要
对水下等离子体电声转换现象的微观粒子运动过程和宏观声场分布及演变过程进行了深入的动画建模仿真。其中微观粒子运动过程逼真地演示了水下等离子体的产生、放电通道的形成、放电过程中气泡生成、膨胀、收缩和破裂的各个典型过程,而声场分布及演变过程则利用声学软件对在反射体内及水中自由场中各个时刻声压的分布、强度和演变过程进行了细致地展示。整个仿真过程利用3DSMAX实现三维立体效果,做到了微观与宏观的结合,仿真结果和模型与实际系统物理参数真实对应,为研究水下等离子体电声转换的机理与特性提供了良好的仿真平台。
A simulation system was proposed for the underwater plasma electro-acoustics conversion,which includes both the microcosmic particle process and the macrocosmic sound field distribution and propagation process.The first part demonstrated the typical underwater plasma evolution process,the discharge channel formation and the process of bubble generating,expanding,shrinking and breaking.In the second part,the sound field distribution and the dynamic propagation process from the electrode to the reflector and to the outside free field water space were obtained through the sound field simulation software(ANSYS).The whole simulation system demonstrates both the microcosmic and the macroscopic process.Its model exactly follows the physical parameters of the real prototype and is finally implemented using 3DS MAX software.The simulation system provides a good platform for studying the mechanism and the characteristics of the underwater plasma electro-acoustics conversion.
