2. dynamics analysis : by setting up jacon matrix differential coefficient sport is passed to descartes space. it makes terminal executing manipulator produce differential coefficient of acceleration and force in every different coordinates can be got. then the effective inertia, coincident inertia and gravity load of two manipulators are calculated by lagrange method. so generalized joint torque of each joint is got, and along with equivalent driving torque, actual driving torque of each joint can be worked out. 3
動力學分析：建立雅可比矩陣將關節空間的各關節的微分運動傳遞到笛卡爾空間，使末端執行器位姿產生微分運動，以用於求加速度及力在不同坐標系間的線性變換，再用拉格朗日法計算兩機械手的有效慣量、偶合慣量、重力載荷，從而計算得到各關節的廣義關節力矩，並與等效驅動力矩共同算得各關節的驅動力矩。 -
The preferences are analyzed, pipe ’ s parameters such as depth, thickness, pipe diameter, and mechanical property of material ; soil parameters such as soil types, internal friction angle, pipe - soil interaction ; fault ’ s parameters such as fault types, fault throw, fault drop, fault - pipe angle, mechanical property of material ; load types such as gravity force, linear displacement load, seismic load and seismic wave. some conclusions are drawn from the calculating results : when buried pipes cross fault, pipe ’ s embedded depth should be shallow, and big pipe diameter and thick wall should be selected. avoid the site where fault moves severe, and select suitable pipe - fault angle
在有限元三維模型建立中考慮的因素有:管道自身參數如管道埋置深度、管壁厚度、管徑、管道材料等;巖土材料參數如土體類型、巖土的內摩擦角、管土相互作用等;斷層考慮有斷層類型，斷層斷距，斷層錯動距離，斷層與管道的交角，斷層材料的考慮等;荷載分別考慮靜荷載，動荷載，其中動荷載包括線性位移加載、地震力加載和地震波加載等。 -
Self - erection system is applied to construction of most of modern large span concrete bridges. in the process of construction, cantilever beam is changing continuously because of the gravity of concrete, the stretching force, the load and temperature variation etc. in order to ensure that two cantilevers constructing opposite can normally close up and that the bridge linearity can accord with design, flexibility deformation has to be monitored
現代大跨度混凝土橋梁多採用自架設體系施工，在混凝土自重、張拉力、橋面荷載、溫度變化等的作用下，懸臂梁體處于不斷的變化之中，為保證對向施工的兩端懸臂能正常合攏和控製成橋線形符合設計要求，需要對施工過程中的撓度變形進行監測。 -
When cable interacted under the load both of gravity and inertia force, derivative equation of cable ' s defection curve in space is deduced to study cable ' s rigidity movement, and flexible deformation is also determined by finite element method
分析了懸索上各離散點的位置、速度、加速度和慣性力。推導了在重力和慣性力共同作用下懸索的空間撓曲線微分方程，並研究了懸索的剛體位移和彈性變形。
