水一聲發射器
英文
submarine sound transmitter-
Based on apdl, the design language of finite element analysis software ansys, and visual c + +, the software on acoustics design of underwater cylindrical shell structure is developed. when input parameter of the cylindrical shell in the interface redeveloped in this paper, the software execute the batch file of apdl in the vc process to establish the finite element modal and carry out the analysis, the analysis result and the vibration mode can also be displayed. furthermore, the software has been developed to process the acoustics optimization design of the finite cylindrical shell with stiffener in appointed frequency range
本論文從便於工程實際應用出發，對使用有限元分析軟體進行二次開發以方便結構振動分析及改進結構設計的方法和過程進行了研究，在此基礎上對水下航行器圓柱殼體的結構聲學特性進行了分析，在指定頻率區間，對結構以振動輻射聲功率級為目標函數進行了部分參數的結構優化設計，與此同時，為了方便有限元分析軟體的使用和簡化設計過程中大量重復的工作，利用ansys提供的參數化設計語言apdl （ ansysparametricdesignlanguage ）結合vc對有限元軟體ansys進行了二次開發，形成了一體化的水下圓柱殼體結構聲學設計軟體。Through the internet, by using another transducer as signal receiver, the b & k hardware and ni software are networked connected, and are combined to give a complete signal process system
藉由單一水下聲音傳感器，控制發射八種不同頻率之水聲，用以模擬多枚傳感器功能；再藉由另一隻傳感器之接收，經由訊號處理及辨識達到簡易之內定通訊及控制指令。
