【摘要】：在现代城市中，高层建筑越来越多的林立，给人们的生活带来了居住云端的感觉。同时，也给人口膨胀的今天实现了人人有房住的美好愿望。在每个高层，小高层建筑里，电梯就起了无可替代的作用。可以这么说，正是因为有电梯，才给了大楼长高的可能性。本文主要内容就瞄准了电梯里的支架。支架安装于电梯的井道，连接墙体和导轨，起到将整个电梯的力转移到墙体的作用。是很重要的承力构件，而对于整个导轨系统的变形也起到了至关重要的作用。其强度的高低，直接影响着电梯的稳定性。而其数量又由楼层高度决定，楼层越高，用量越大，也就不能不考虑成本。但是我们不能牺牲质量，要达到两者的平衡，在满足强度的同时，需要优化结构，合理配置，节约材料和成本。这就是这次研究的意义。本文通过对两种平台共用支架设计进行思考，得出根据经验的优化结构，再运用Hyperworks的OptStructure进行模型优化，选取目标函数，寻求最优解。得出第二次比较精确的优化结果。在材料节约的基础上增加刚度。在两次优化的基础上，对模型重新建立，并利用pro族表对支架进行配置，使之能用于各种条件下的井道，满足layout要求。对于最后优化好的支架，再次进行分析，在平台环境的基础上，，利用Hypermech进行前处理，利用ANSYS进行加载和求解，并通过后处理最终得出结构的分析结果。
[Abstract]:In modern cities, more and more high-rise buildings, to people's lives brought the feeling of living in the cloud. At the same time, but also to the expansion of the population today to achieve a good wish for everyone to have a house. In each high-rise. Elevators play an irreplaceable role in small high-rise buildings. The main content of this paper is aimed at the support in the elevator. The support is installed in the shaft of the elevator, connecting the wall and the guide rail, and plays the role of transferring the whole elevator force to the wall. It is a very important component. And the deformation of the whole guideway system also plays a vital role. Its strength directly affects the stability of the elevator. And its number is determined by the height of the floor, the higher the floor, the greater the consumption. But we can not sacrifice quality, to achieve a balance between the two, in order to meet the intensity of the need to optimize the structure, reasonable allocation. Save materials and costs. That's what this study is about. In this paper, we think about the design of common support for two platforms, get the optimized structure based on experience, and then use OptStructure of Hyperworks to optimize the model. The objective function is selected to find the optimal solution and the second accurate optimization result is obtained. The stiffness is increased on the basis of material saving. On the basis of two optimizations, the model is re-established and the support is configured by pro family table, which can be used in various conditions to meet the requirements of layout. For the final optimized scaffold, again analysis, on the basis of the platform environment, using Hypermech for pre-processing, using ANSYS to load and solve. Finally, the result of structure analysis is obtained by post-processing.
