The cable - strut tensile structures are the self - stress equilibrium systems composed by tensional cables and struts. in this paper, the basic concept of the structures was described. the analysis methods of the structural characteristics ( statically and kinematically determinate or indeterminate ) and the geometrical stability were presented. it is indicated that the cable - strut tensile structures are in stable equilibrium with first - order infinitesimal mechanisms. the ranks of equilibrium matrix were calculated by employing the singular value decomposition, and the independent modes of inextensional mechanisms and the states of self - stress were also obtained in the same way. this paper contains some typical examples which illustrate all of the main points of the work
索桿張力結構是指由張力索和壓桿組成的、具有預應力自平衡的新穎結構體系.本文詳細闡述這種結構的基本概念和結構特徵，討論結構靜動定體系特性和幾何穩定性判定分析方法，指出索桿張力結構應具有一階無窮小機構的幾何穩定體系.文中採用奇異值分解方法計算結構平衡矩陣的秩，並計算獨立機構位移模態和自應力模態.最後，對幾種典型的索桿張力結構進行了算例分析 -
Abstract : in this paper, the kinematically admissible velocity fields are established by using the metal flow patterns based on the experiments, and the configuration dimensions of billet and the curves of load - stroke in precision forging process for spur gear from solid billet are simulated on computer by upper bound method. the results acquired in the simulation are in good agreement with those obtained in the experiments
文摘:本文利用有實驗根據的變形流動模式建立動可容速度場，利用上限法模擬用實心坯料精鍛直齒圓柱齒輪時坯料的外形尺寸變化和力?行程曲線，所得結果與實驗測定值很一致，可供沖擠精鍛工藝設計參考。 -
Because the kinematically - admissble cyclic strain rate field required in kninematical - type theorem of shakedown analysis is rather difficult to be constructed, shakedown analysis based on kinematcal theorem cannot be directly applied. some conditions of kinematical - type shakedown theorem are released by ksnig and then the shakedown rules respectively for alternating plasticity and incremental collapse are obtained, for the numerical method based on the upper - bound theorem is formulated
兩種方法的特點是：運用一種分級循環加載方式來尋找機動許可的塑性應變率場，利用這兩種機動安定準則的特點來判斷結構的安定性，從而得到機動安定性分析的安定載荷。 -
