介紹了一種新型的扭矩轉速儀，其特點是採用了高性能的risc單片機，電路簡潔、可靠，低成本地實現了兩路扭矩及轉速參數的自動測量、數據處理、數字顯示與記錄，並具有數據聯網介面。From above analysis, the thesis gets conclusions as following : ( 1 ) the frequencies of multi - tower building are so dense and the coupling in each mode is so evident that the cqc method instead of srss should be used to calculate the seismic action effect ; ( 2 ) torsion effects is distinct between the modes of asymmetry multi - tower structure and it is necessary to take translation - torsion coupling into account ; ( 3 ) the effect of the enlarged base rigid on the seismic properties is very big, the rigid ratio of the enlarged base to towers in asymmetry multi - tower structure should be designed in a proper range ; ( 4 ) the distribution of plane rigid is asymmetry because of the asymmetry layout of towers. the torsion effects of structure not only result in large torsion internal force in vertical element resisting lateral displacement, but also make large influences on the stress of transfer plate and near floors, thus it is necessary to strengthen those floors
通過上述分析，得出以下主要結論：多塔樓結構存在頻率密集現象，各振型間耦聯效應明顯，地震作用計算應採用cqc組合原則而不能簡單地採用srss組合原則；非對稱多塔結構的振型中，扭轉作用明顯，平扭耦聯效應值得考慮；裙樓剛度對整體結構的抗震性能影響很大，非對稱多塔結構宜控制裙樓與塔樓剛度比在適宜的范圍；非對稱多塔易導致平面剛度分佈不均勻，結構扭轉效應不僅在豎向抗側構件中引起較大的扭轉內力，對轉換層樓板應力有較大的影響，且延續至相鄰樓層，對相應樓層均應採取相應的加強措施。Aluminium and aluminium alloys. copper and copper alloys. simple torsion test for wire

文章首先對箱形梁進行研究，分別基於umansky約束扭轉理論和gielsvik約束扭轉理論推導了箱形梁在純彎作用下的彈性臨界彎矩，並進行了比較，發現基於gielsvik約束扭轉理論的臨界彎矩具有較好的精度且形式簡單。In this paper, the investigation of tosional vibration of shafting in china is compared with the advanced level of other countries. some basic theory and computing methods are discussed in many chapters
本文分析了我國軸系扭轉振動研究的情況及與世界先進水平相比較的差距；簡單介紹了扭轉振動的一些理論和計算方法。As a result, shifting of the fundamental frequencies and redistribution of stress in the blade base possibly cause failure of the blade. a three - dimensional finite element model of a blade and its fir - tree attachments have been constructed and analyzed with taking into account of contact nonlinearity in the attachments and large deformation effect of the blade. the geometry mismatch was introduced into the finite element model by defining gaps between two contact surfaces in the attachments
分析結果表明葉根誤差發生的位置對葉片彎曲振型的固有頻率影響較大，對扭轉振型影響較小;誤差的大小對葉片各階固有頻率影響均較小，但對葉根應力分佈有影響;比較發現，在計算固有頻率時，將葉片在葉根處簡單地處理成固支位移邊界是不合理的。分享友人
