将一种四角加衬垫的物品看作刚体 ,衬垫看成弹簧 ,列出物品包装跌落时运动方程 ,以物品加速度、衬垫尺寸应满足一定的要求为约束条件 ,包装衬垫材料费最低为目标函数 ,进行优化设计 ,并得出物品最大加速度与衬垫材料特性、厚度、承压面积的关系。编成优化设计软件及三维图形显示软件 ,为物品包装缓冲结构计算机辅助设计奠定了基础。 Think of a four-corner padded article as a rigid body and a cushion as a spring, and list the equation of motion when the package falls. The acceleration of the article and the size of the pad should meet certain requirements as constraints, and the minimum cost of packing the padding material As the objective function, optimize the design and get the relationship between the maximum acceleration of the article and the characteristics of the cushioning material, thickness and bearing area. Compiled into the optimal design software and three-dimensional graphics display software, the article packaging cushioning structure of computer-aided design laid the foundation.
