大型折叠式看台系统设计研究

Design and Study of Large Folding Grandstand System

摘要: 在物质文明高度发展的今天，精神文化的需求同样不能忽视，因此娱乐(演唱会、歌剧院等)场所已然成为了人们休闲的重要场地。面对庞大的市场需求，自由折叠的临时看台便是第一选择。对此，设计出了一种具有可折叠结构的看台，该看台由减速电机完成自动折叠或者手动折叠，可以根据不同需求选择不同规格的看台，避免了传统临时看台搭建上的时间及后续拆卸问题，并且可以实现循环利用。此外，对看台进行承重校核计算，以及有限元分析，其分析结果验证了该系统的正确性和机构的合理性，为大型折叠式看台结构设计提供了一种方案。

Abstract: In recent years, with the high development of material civilization, the needs of spiritual culture cannot be ignored, entertainment venues (concerts, opera houses, etc.) have become an important venue for people to relax. In the face of huge market demand, the free-folding temporary stands are the first choice. In this regard, a kind of bleacher with foldable structure is designed. The bleacher is automatically folded or manually folded by the deceleration motor. Different specifications of bleacher can be selected according to different requirements, which avoid the problem of time and subsequent disassembly in the construction of traditional temporary bleacher, and can be recycled. In addition, the load bearing calculation and finite element analysis of the bleacher show that the bleacher meets the use needs and conforms to the national standard.
