折叠结构体系及类型

Folding Structure System and Type

基于广义分类学理论,对折叠结构体系进行了分类研究,建立了一套适合于折叠结构特点的分类体系,并分别对折叠结构体系中的杆系折叠结构、索杆系折叠结构和板式折叠结构的构成进行了分析。在此基础上,运用结构拓扑学原理对折叠结构体系进行了结构拓扑分析,建立了杆系折叠结构、索杆系折叠结构和板式折叠结构3种不同类型的结构几何稳定性的判别标准。结果表明,按照所提出的方法,解决了在进行折叠结构设计时靠经验来判别其几何稳定性的局限性,保证了折叠结构设计的安全性和合理性。

Based on generalized taxonomy theory and aimed at folding structure system, authors proposed a theory about classification system that could be fit for the characteristic of the folding structure system. At the same time, the constitutions of bar folding structure, bar-cable folding structure and flat folding structure were analyzed. On the basis of the constitution and structural topology analysis of the folding structure system, authors put forward a theory about the geometric stability criterions of the bar folding structure, bar-cable folding structure and flat folding structure. The results show that the geometric stability criterions can resolve the limitation of experience design and ensure safety and rationality of folding structure design.
