白卡纸结构模型力学探究

以白卡纸、502胶水为原材料制作巨型框架、空间桁架、平板网架等结构模型,进行动静载的承载破坏试验,分析不同结构体系的力学性能。探究表明:格构式结构体系的力学性能,格构式选型承载力大大提高。材料力学性能不够理想的白卡纸在赋予其良好的结构体系时,也表现了优良的承载能力。

Using white jam paper and 502 glue as raw materials,the structural models such as mega-frame,space truss and flat space truss are made,the bearing and failure tests of dynamic and static loads are carried out,and the mechanical properties of different structural systems are analyzed.The results show that the mechanical properties of lattice structure system and the bearing capacity of lattice type selection are greatly improved.When the mechanical properties of the material are not ideal,the white jam paper also shows excellent bearing capacity when it is endowed with a good structural system.
