Tower Crane

Advantages and disadvantages of present tower crane's upper structures are analyzed in this paper. According to the theory of prestressing jib, through combination design, a kind of structure is presented which can realize multiple use and greatly improve the hoisting capacity. Mechanical analysis and contrasts are done for old and new designs by finite element analysis software ALGOR. Finally, an example is given to verify the validity and feasibility of the design

Working aluminum towers is bound to meet the materials, dimensions, design load, safety and performance requirements of the standard EN 1004. Using the FEA(Finite element analysis) software ANSYS, the mechanical analysis of a 8m height tower made of prefabricated elements, according to standardization EN1004,is done in this paper. The geometric imperfection, Such as inclinations between vertical components the inclination position of 1% and the minor eccentricities of castor should be taken account into the finite element model.This template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications.

A feasibility study was conducted to determine the use of polyphthalamide/glass-fiber and polyphthalamide/glass-fiber/polytetrafluoroethylene-based composites as substitutes for aluminum and steel, respectively, in the production of motorcycle oil pump parts (housing, shaft/inner gerotor and outer gerotor). New and used (80,000 km) oil pumps were subjected to performance tests, whose results indicated that the pressure and temperature of the used pump reached a maximum of 1.8 bar and 93℃, respectively. Thermogravimetric analysis indicated that the materials are stable at the maximum operating temperature, which is 20℃ lower than the minimum glass transition temperature obtained by dynamic mechanical analysis for both materials at the analyzed frequencies (defined after calculations based on rotations in neutral, medium and high gear). The pressure value was multiplied by a safety factor of at least 1.6 (i.e., 3 bar), which was used as input for a finite element analysis of the parts, as well as the elasticity modulus at glass transition temperatures obtained by dynamic mechanical analysis. The finite element analysis indicated that the von Mises stresses to which the composite parts were subjected are 7 to 50 times lower than those the materials can withstand. The results suggest that it is feasible to manufacture motorcycle oil pump parts with these composites.

Ensuring that deployable mechanisms are sufficiently rigid is a major challenge due to their large size relative to their mass. This paper examines three basic types of stiffener that can be applied to light, origami-inspired structures to manage their stiffness. These stiffeners are modeled analytically to enable prediction and optimization of their behavior. The results obtained from this analysis are compared to results from a finite-element analysis and experimental data. After verifying these models, the advantages and disadvantages of each stiffener type are considered. This comparison will facilitate stiffener selection for future engineering applications.

According to uncertainty of the design parameters for large span truss of installing wave-maker, in order to avoid the waste of materials,the truss is analyzed based on the finite element analysis software ANSYS to find out its weaknesses and various parts of the deformation. On the premise of ensuring the intensity and stiffness, the weight of the truss is reduced by adjusting its sizes and selecting different profiles, so as to achieve the optimization of the truss of installing wave-maker.

For the high hoisting height, wide using range, tower crane is widely utilized in the architecture construction, while there are some deficiencies in the high rising architecture such as chimney, so the performance can’t exerted. By virtue of computer aided technology, the finite element static analysis of metallic structure of unconventional dedicated tower crane is conducted in this paper, and the figures of stress and displacement are achieved for the two working conditions and two structures. It is proved that the results are satisfied the requirements of stiffness and strength, and also foundation is established for the further analysis.
