The stress cloud diagrams, velocity and acceleration dynamic response of the furniture structure, which were analyzed . comparatively with the material properties, were obtained by analyzing response of its structure when dropping. The cost and expense of actual measure could be saved. It verifi ed the rationality of the solid wood chair structural design g by using fi nite element methods. It is also a discovery that how the computer dropping simulation technology could be applied to analysis of furniture structural stress. r Solid wood furniture; Finite element method; Simulation analysis of dropping; ANSYS/LS-DYNA KeyWords:KeyWords: 库 o 例 . 目前已有研究者利用有限元原理，对实 对各种工业产品进行跌落数值分析是 则如下： 案 木家具的静态承载能力和结构强度进行了分 ANSYS/LS-DYNA的一个重要的应用领域。利用 1）所有的倒角和线型均改为直角。例如 E o e 析研究，并与实际试验数值作比较，验证了 LS-DYNA提供的跌落
