單向彎曲-
Using the similarity between plane elasticity and plate bending, this paper successfully fulfils the identification of rolling vector and establishes a general method, the curvature lumping method, to represent the rolling vector by the use of simple displacements vector
利用平面彈性和板彎曲的相似性，本文實現了角卷向量的辨識並得到了用簡單位移向量表示角卷向量的一般方法?曲率堆集法，打通了與有限元通用程序的介面。 -
The hspice simulation result shows a temperature coefficient of 11 ppm / " c from - 40 ? to 100 ' c and output voltage variation of 1mv for supply voltage range from 8 v to 18 v. due to novel curvature compensation, the circuit structure of the proposed reference is simple and both chip area and power consumption are small
Hspice模擬結果顯示：該基準源在- 40 100的溫度變化范圍內，具有11ppm的低溫度系數；當電源電壓在8 18v變化時，輸出電壓變化量僅為1mv ；並且電路結構簡單，具有較小的晶元面積和功耗。 -
It analyzes the dynamic response of many different damage cases of simple i - shape beam structure and discusses their influences to natural frequency and modal curvature. it is found that the natural frequency and modal curvature can be used in identifying the severity and location of structural damage respectively. dynamic response of some real beams are measured and compared to the results analyzed by computer, it is found that there are some differences between them and the main reason is the error caused by modeling
2 .針對土木結構中最為常見的梁式結構，對簡支工字鋼梁的多種不同損傷工況的動力特性進行了有限元模擬分析，研究了損傷對頻率和模態曲率的影響，發現固有頻率變化率和模態曲率的變化分別可以用於損傷程度和損傷位置的識別;在實驗室中實測了幾種工況的鋼梁的振動模態，發現實測結果與計算結果有一定的差異，分析其原因主要是模型誤差和噪聲影響。 -
The application of the three damage identification techniques above for simple supported beams and cantilever beams confirm that vague or wrong location will occur in the damage location method based on flexibility difference, and the curvature modal method need not rely on the structural parameter before the damage, but has the hidden trouble of vague location for small damage
將以上三種損傷識別技術應用於簡支梁、懸臂梁的模擬損傷識別，證實了基於柔度差值的損傷定位方法存在模糊或者錯誤定位的問題，曲率模態法可以不依賴損傷前的結構參數，但對于小損傷也存在模糊定位的隱患。
