Analysis on Parameter Model of a Flat Folding Table

A mathematical model is established to solve the dynamic change process and parameter design of a creative flat folding table. Firstly,the length of the rotated part and un-rotated part of the table stick is computed based on plane geometry. Then a space rectangular coordinate system is built to represent the coordinate points of the two ends of each stick by using the method of three-dimensional geometric analysis. Thereafter,the flat state and the final rotation state are analyzed to calculate the length of slot. Finally,the coordinate of the stick end and the angle between the stick end and the ground are represented by the space rectangular system. The corner of the table edge is drawn by using three-dimensional space curve fitting. Therefore,the dynamic process of the folding table is described by using angle and the table edge line.
