Development of Parameterized Modeling for Tower Crane

Abstract:

The development of parameterized modeling for ST8075 tower crane is based on finite element analysis software SAP84 and high-level programming language Fortran. According to the Saint-Venant principle, the special beam elements such as rotation joint and connection knots are specially reinforced if they don’t affect force analysis and deformation analysis of the whole structure. The tower crane is built into many small modules, which include balance arms, booms, tower body and so on. The developed program for the tower crane can realize the following functions: inputting the following parameters such as the tower body standard joint number, the boom combination type, working amplitude and hoisting weight, the computer can automatically generate hoisting points and get required crane with any tower body standard joints and booms’ combination type. According to inputted boom combination type and amplitude, the program will automatically judge the balance weight value applied to the balance arm, apply the balance weight, assure the variable-amplitude vehicle’s position, apply the hoisting load, apply the hanger weight and generate data files. It can calculate tower crane’s force state when the crane is working at various working case such as working state and storm case. After calculating the crane, inner forces can be checked and judged whether the beams meet the requirements of strength, stiffness and stability. It is easy to optimize the product design, reduce the crane’s potential risks and raise its safety assurance. It has important significance for research and development of new products.
