Research And Static Analysis Of The Mechanical System Of Retractable Roof

A retractable roof is a new type of architecture which part of, or all of the entire roof can be moved or retracted within a period of time. Not only it endows the normal buildings with new functions, it also adds the aesthetic elements to the buildings. The mechanism of the retractable roof is the key point of the realization of the retractable function, so it is quite important to design a good mechanism for the retractable roof.In this paper, the retractable mechanism system and the structural load of the mechanism is analyzed through the theoretical analysis, modeling and experiment. This work has a theoretical guidance value to the design of retractable roof.This paper is summarized as follows:First, the background and significance of the topic were discussed. The functions, applications and the history are introduced and the research highlights were summarized.Second, the retractable mechanical device for retractable roof was generalized on the basis of the thoroughgoing study about the principle of retractable roof. There are two kinds of retractable roof, including rigid retractable roof and flexible retractable roof. On the basis of systemic classification of the retractable mechanical device, the concrete implement of all sorts retractable mechanism was proposed and the characteristic and application were illustrated.Third, analyzed the difference between the technology of the retractable roof and the crane. Expounded the method and outlines of the mechanism design of the retractable roof.Fourth, this paper proposed to adopt a method which combined structural analogy and analysis of the geometry impact factors to analyzed the structural load of the mechanism system. For one mobile roof project in Hangzhou, established the mathematical model of the bending of the mobile roof, and analyzed the structural impact factors using ANSYS. The results could be used in the analysis and calculation of the structural loads of such type of the retractable roof.Fifth, according to the similarity theory, made the corresponding physical model of the retractable roof, then did the mechanics experiments. The results shows the two methods are feasible after comparing the date of model experiments with the date of ANSYS simulation,...
