條矩陣法-
The transfer matrix method of bar elements with variable cross - section
變截面桿元傳遞矩陣法 -
This paper presents the element stiffness matrix and equivalent node force of the variable cross - section bar. so the approximation in structural analysis is avoided, and the calculation capacity of equivalent frame method is also developed. this helped the engineers avoid the fem, which consume much time and is difficult to master
本文對板帶寬度變化的板柱結構推導了變截面直桿單元的單元剛度矩陣和等效結點荷載列陣，避免了在結構分析時所作的近似，也擴大了等代框架法的計算范圍，使工程技術人員免於使用佔用機時、難于掌握的有限元分析法。 -
The kinematic synthesis equations for rrr and rpr groups have been established, respectively, based on the single - opened - chain ( soc ) theory and displacement matrix method. combining two kinematic synthesis equations for rrr groups, this paper presents the unified kinematic synthesis equations for hinged 3 - bar groups which are applied in function synthesis of planar watt, stephenson, and 6 - bar linkages
基於單開鏈理論，應用位移矩陣法，分別建立了rrr和rpr兩種級桿組的運動綜合方程，再將兩個rrr級桿組的綜合方程聯立，得到watt型及stephenson ，型六桿函數發生機構中鉸鏈三桿組的統一運動綜合方程組。 -
In the paper the characteristics and dividing methods of cells, as well as some relevant computer programmes are given, which have proved to be correct by several examples of structures of bar system the calculation of the new method is simpler because it need not form the global stiffness matrix that is necessary in fem, and solve the boundary problems of partial differential equations
在此基礎上給出桿系的細胞自動機模型、單元劃分方法、單元特性和演化規? ?則。並列出了該方法的計算步驟。通過數值計算分析，驗證了該方法的正確性，算例表明該方法對結點位移和桿內力收斂速度較快。 -
