Finite element analysis of a tower

The results show that, to reduce the cracking damage caused by oversized shearing stress in asphalt pavement, we should first consider the damping ratio of surface layer material, and the most effective method is to use the road-building material of high damping ratio to prevent cracks, at the same time we should raise the driving speed.

Taking a variable diameter Independent pile in CB11F platform of Chengdao oilfield for example, simulative analysis is performed using the finite element software ANSYS , considering the influence for some factors to structure response, that is environmental load, soil conditions and variable diameter position. This essay is mainly about doing research on flow-induced vibration response of power station expansion joint structure, putting the flow pulsating pressure load of expansion joint tested into numerical model to calculate, and making evaluations about its engineering safety. The results of calculation indicate that the optimization program has a significant effect on controlling the decreasing amplitude of the max displacement and stress, which makes sure of the safety of generating system. The Mmodal analysis provided theoretical basis for safe use, design and transformation of this crane. This method could be used to the dynamic analysis on the structures of simultaneous effect of many different frequency sinusoidal load. A kind of new system of load distribution beams was applied, which imposed the horizontal loads to load points of columns and simulated the uniformly distributed wind load. The performances of the light steel temporary building are summarized and discussed. Also, we studied on the impact of damping ratio and the driving speed on shearing stress. The load-displacement curves and the strains of the columns were obtained. This method could be used to the dynamic analysis on the structures of simultaneous effect of many different frequency sinusoidal load. The conclusion is mainly as follows: the change of width and thickness of cross beam exerts slight impact on the maximum stress of the node while the change of cross beam depth impacts the node stress much. With regard to the problems existing in this engineering project, we bring forward the corresponding design proposal of optimization. An finite element model of vacuum autoclave was established and the buckling load calculations under the extreme operating conditons have been carried out to obtain the modal deformation condition and the safety factor. From the computation, it can be concluded that proper reduction of cross beam depth is beneficial to the node stress. Finally, by using SPSS
