代數方程的拉格朗日乘子方法A method is proposed for the parameter identification of the viscoelastic internal dampers of the multirotor systems in this paper. the multi - rotor system is regarded as a composite structure. the impedance matching method in the substructure method for structural dynamic analysis is used for the dynamic calculation of the structure. the augmented lagrange method is applied to the iteration calculations of the characteristic determinant of eigenvalve equation of the system. and then the results of parameter identification can be obtained. upon the dynamic characteristics of the system, the method can reveal the influence of the gyroscopic moments of force precisely. in process of the analysis, the various properties of multi - rotor systems are made the best use of, so the measure of the modes parameters is avoided, the calculation is simplified. in addition, an efficient method is proposed to establish a dynamic model of multirotor systems with viscoelastic internal dampers. the calculating results are consistent with the experimental results satisfactorily
提出了多轉子系統的粘彈性中間彈支參數辨識的一種方法.該方法把多轉子系統看作復合結構，用動態子結構分析的阻抗匹配法計算動力學特性，用增廣拉格朗日乘子法迭代計算系統特徵方程的系數行列式，獲得系統物理參數的辨識結果.該方法可以準確計入陀螺力矩的影響，避免測量振型參數.在分析中，利用多轉子系統的特性可簡化分析過程.文中還介紹了一種建立粘彈性彈支多轉子系統動力學模型的方法.計算結果與試驗結果基本一致M there are considerable number of research concendng finie elemen method on contat problem and lot of techniques such as iteraion methd, mathematics propoming, penalty method, langrange multiplier and so on hav been developed, it is not easy to popularize the presemed methods to engineering. " field due to their complicate techniques. ms prompts the author to develop an wash that is simpler in techniques and can be @ plied to geotecilllital problems iv with less difficulty
雖然目前接觸問題有限元計算已有大量的研究成果，所提出的求解方法也很多，如直接迭代法、數學規劃法、罰函數、 langrange乘子法等，但其求解技巧普遍比較復雜而不易在工程領域推廣應用，在巖土工程中的應用則更少，因此，本文的主要工作是建立一種比較簡單、方便、能夠用於工程問題的接觸問題的計算方法，而其關鍵是相應的有限元計算公式的建立。The main content of the present paper is as follow : in the first part, this paper gives the definition of lfi algebras and clfi algebras ; discusses the properties of fi algebras, theirs mp filters. lfi algebras and lfi algebras with embeddability
