工廠製造的鋼罐.易燃和不易燃的水污染液體地下儲存用臥式圓柱形單層和雙層鋼罐The cosine transform spectrum of sphere are about the same as that of infinite horizontal cylinder, and that of infinite stretched staircase are very sharp, but that of finite stretched staircase presents well - regulated leap
球體與無限長水平圓柱體的餘弦變換譜相似，無限延伸垂直臺階的變化很尖銳，有限臺階的表現為上、下有規律的跳躍。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。With finite element method, the influences caused by hydrostatic pressure to deformation and failure model of ring - stiffened cylindrical shells are analyzed
