Static Characteristics Research of Bed with Three-Point Support Using Bionics

In order to meet the requirement of small deformation of "T"-shaped bed with three-point support, based on the idea of meta-structure, making use of bionics, a new unit structures - hollow hexagonal prism is put forward. Through the analysis of the static characteristic of the different unit structures, it is shown that hollow hexagonal prism has strong advantages as unit structures. Thereafter, using hollow hexagonal prism of different cross-section circumcircle diameter and wall thickness as unit structures of "T" shaped bed, through the bed static characteristics analysis, the design principles of bed designed by the use of hollow hexagonal prism is summarized.
