创意平板折叠桌的建模与分析

Modeling and Analysis of the Creative Rising Side Table

为解决目前市面上出现的一种创意折叠桌的自动设计问题,先讨论了简单常用圆形折叠桌的建模问题,用微元法通过桌面边缘点及桌面与桌脚夹角的关系建模得到折叠桌桌脚的动态变化模型.由此可求出圆形折叠桌的开槽位置及长度等加工参数.随后从稳固性、加工便利性、耗材等方面讨论了加工参数的优化设计.发现对于桌面形状任意的创意折叠桌,只要用户给出桌面边缘曲线,都可以建模计算出一组稳固性、耗材和耗工优化的加工参数,并以椭圆形折叠桌为例讨论了给定高度和宽度的椭圆折叠桌的建模计算.最后,讨论了折叠桌的建模仿真并给出了关键仿真代码.

In order to solve the automatic design of a kind of creative folding table in the present market, the modeling ofsimple circular folding table is discussed at first. Dynamic change of folding table legs is modeled as the relationship between thedesktop and the angle of the table foot with differential method, with which the processing parameters such as the position andlength of the round table can be obtained. Then the optimization design of processing parameters is discussed from the aspects ofstability, processing convenience, material and so on. The analysis shows that a set of optimization parameters with stability,consumables and industrial processing can be calculated for an arbitrary creative folding table as long as the user provides thedesktop edge curve of its. And then the modeling and calculation of the elliptical folding table with the height and width arediscussed. At last, the simulation of the folding table is analyzed, and the key simulation codes are suggested.
