总裁椅用搁脚机构设计及其力学性能研究

THE STRUCTURAL DESIGN OF BOSS CHAIR FOOTREST AND IT'S STUDYING ABOUT MECHANICAL PROPERTY

针对客户需求,依据人机工程学原理设计了一款总裁椅用搁脚机构。运用Adams软件对建立的三维模型进行运动学仿真,验证了机构的运动特性,基于AWE环境对机构进行有限元分析,校核了结构的强度和刚度,在实物样机的基础上进行力学性能测试。结果表明,设计的搁脚机构满足人机尺寸要求和运动平稳性要求,结构的静强度、疲劳强度和刚度符合BIFMA测试标准,试验研究结果与有限元分析结果相符合。

According to customers＇ needs,Based on ergonomics principle,a Boss Chair footrest was designed. Using Adams software to take kinematics simulation,which has verified the movement characteristics of the organization. Based on finite element analysis AWE environment on the organization,To check the strength and stiffness of the structure. On the basis of the physical prototype,to take mechanical properties test. It turned out that the footrest meet requirements of ergonomics size and movement stability,static strength,fatigue strength and stiffness of the structure conform to the BIFMA test standard. The testing results coincided with the finite element analysis.
