【摘要】 首先针对五斗柜会发生倾覆对五斗柜进行分步、整体力学分析,结果表明空载情况下斗柜整体的质心位置和所受重力决定了其抗倾覆能力的大小;再通过选定市面上某款美式五斗柜进行结构分析,并进行结构简化,然后通过对不含抽屉的柜身部件及抽屉部件建立坐标系并进行质心坐标转化,利用组合法得出了在空载状态下能反映整柜质心位置一般规律的方程;最后通过在Adams软件中进行运动仿真验证了理论推导的合理性,得出在空载状态下整柜质心与抽屉拉开长度呈正相关,质心高度位置始终为常量,为进一步研究各种复杂加载情况下五斗柜的稳定性奠定了基础。更多还原

【Abstract】 The stepbystep and overall mechanical analysis of the chest of drawers showed that the antioverturning ability was determined by the position of the centroid and the gravity of the chest of drawersunder noload conditions. An Americanstyle chest of drawers was selected and it’s structure was simplified after structure analysis. By establishing a coordinate system for the chest parts without drawers anddrawer parts,a kind of combination method was set up with transforming the centroid coordinates.Through the combination method, the general law of the position of the centroid of the chest of drawerswas finally verified by the motion simulation in the Adams software. The conclusion is drawn that the centroid of the whole chest of drawers is positively related to the length of the drawer under noload state,andthe height of the centroid is always constant,which laid a foundation for further research on the stability ofthe chest of drawers under various complicated loading conditions.chest of drawersno loadcentroid positiongeneral law更多还原
