Research Of Force Dispersing Technique Of Long-distance Flexible Adhesive System Of Super Flat Bridge

As the world’s rapidly increasing energy demand, the electric power industry obtains the enormous development. As the power plant unit power increases, the cooling tower size is also getting bigger and bigger. The market is getting more and more urgent to the cooling tower construction special purpose equipment’s demand. The topic is part of "11th five-year" plan, dedicated mainly to domestic cooling tower construction equipment-hydraulic jacking flat bridge, research long-distance range flexible adhesion scattered technology.As a dedicated power plant cooling tower construction equipment, since the high degree of independence is difficult to meet the work requirements. According to stability, strength and stiffness conditions require, determine the deck height of the largest independent formula was derived in the article. Take the stability as the datum, and considered that adheres to stick cohere system’s elasticity effect, the Euler critical load equivalent method and the transfer matrix method are used to derive formulas attached to attachment spacing. The impact of the flexibility of the attachment system attached to distance is qualitative and quantitative analysis.If the angle of torsion is oversized, the objects and the platform will be torsion deformation. it is disadvantageous to the construction. According to analysis and comparison of the current flexible arrangement of the torsional properties of adhesion, New Flexible attached arrangement (the start) is proposed in this artical to meet the application requirement of the flat bridge.The flat bridge is a kind of spatial structure, which is higher mode ultra statically determinate structure, and has non-linear characteristics. As a result of the load, the force of structure is quite complex. The tangential force of wire ropes is treated as the "quasi-linear" form in the article. According spatial force bearing properties and nonlinear characteristics, and considering the axial and torsional deformation of bridge body, the bridge-body was seen as pressure-bending member. Using beam element matrix displacement method, the canonical equation of bridge body is established. The force and distortion of the wire ropes and the bridge body is solved by iterative method. The method is suitable for arbitrary arrangement of flexible attachment, providing theory and method for the engineering.
