休闲椅CAD系统的研制

A Study on the CAD System of the Recreative Chair and Development of the System

针对休闲椅的结构特征和产品设计特点,确定了其机构(空间十杆机构)运动轨迹的数学模型,且在AutoCAD中应用VBA语言建立了休闲椅动态模拟仿真模块;根据工程力学的理论,对空间十杆机构进行受力分析;并运用VB语言对杆件强度、压杆稳定性进行了校核和参数化设计。

According to its structural features and design features. a mathematical model of the movement orbit of the recreative chair is defined. and a dynamic emulation mould is built up in AutoCAD. The mechanism of the recreative chair is analyzed according to engineering dynamics theories. The intensity of the pok and the stability of pole pressing are checked and a parameterized design has been carried out in VBA language.
