中文摘要 | 本文以B-樣條有限條元法分析矩形薄板之自然振動頻率。此法首先將 矩形板離散成條元素,並以三次B-樣條函數及三次赫爾米特插分函數模擬此條 元素之位移函數,進而利用位能與動能之最小化原理,推導出矩形板主勁度與質 量矩陣。最後以實例驗證分析之結果,證明本法可以有效分析各種不同表寬比及 邊界條件之矩形板,並且獲得良好的精確性與適用性。 |
英文摘要 | A spline finite strip method was presented in this study for the natural frequency analysisof the rectangular plates. A plate was discretized and modelled as strip elements. The cubic B-spline functions and cubic Hermite interpolation functions were employed for representing thedisplacement functions of the special element. Stiffness and mass matrices were derivedthrough means of the minimum potential and kinetic energy principles. Plates with variousboundary conditions and different side ratios were analyzed via the proposed method. The accuracy and versatility were confirmed through numerical examples. |
