Issue Date: | Mar-2014 | Publisher: | Chinese Society of Structural Engineering | Journal Volume: | 29 | Journal Issue: | 1 | Start page/Pages: | 107-113 | Source: | Structural Engineering | Abstract: | 在結構動力學中,以Duhamel's integral求解結構承受任意外力之動態反應;而在工程數學中,可以參數變異法(variation of parameters),來求解非齊次微分方程式。本文將兩者作一連結,採用工程數學之參數變異法,推導結構動力學之Duhamel's integral,就數學與物理之觀念,即可求得結構之動態反應。此外,續以參數變異法,延伸Duhamel's integral至多自度結構,使之更具通用性。只要質量、勁度及阻尼為常數矩陣,均可適用,而單自由度結構僅為其中之特例。以工程數學之角度,檢視結構動力學之Duhamel's integral,期對執業之工程師、在學之同學及授課之老師,都有所助益。 |
