本篇論文主要在探討旋轉圓板,當挖有不同形狀之孔洞,並考慮阻尼效應。討論對運動方程式之建立及自由振動頻率值之變化。在旋轉圓板振動方面,因圓板為薄板,故本文沿襲過去研究旋轉圓板之文獻,忽略轉動慣性和橫向剪力效應,只考慮離心力所造成之初使應力。
本文主要利用『Ectoplasm』薄膜變厚度法,應用在旋轉圓板上。『Ectoplasm』薄膜變厚度法的概念為貼一層很薄的薄膜,以變厚度來模擬孔洞部分。因此,可視為板的變厚度之振動問題。
本文探討不同形狀孔洞大小、不同孔洞數目、拘束內外部邊界、轉速不同對旋轉圓板自然頻率之影響,並考慮阻尼效應,加入激振力對不同孔洞板作響應及頻譜分析,以及觀察圓板在周向之位移量,了解含洞旋轉圓板之振動特性。
