Study On Optimized Suitable Arrangement Of Solid Wooden Chair Leg

The report takes the leg of solid wooden chair as the object of study, analyses efficiency and materical utilization of splicing board. The article uses the typical chair leg , carries on different arrangements of the sets of the leg and studies efficiency and materical utilization of splicing board. Through carries on the analysis to the typical chair leg modelling and the parameter, The article obtains the best and highest splice board way, and research the size relationship of the chair leg and arrangemennts.Main contents and results of this study are as follows:(1) The straight line chair leg's best splice formula: When the straight line chair leg accord with K<2AH/ [2D+B/ctg(180- ?1)], common and optimized suitable arrangement will present threshold point n, n represents the numbers of chair leg.When the numbers of chair leg is less than n, length and width formulas of splicing board: L=A; W=B+H(n-1)When the numbers of chair leg is more than n and K>H,length and width formulas of splicing board: L=2D+B/ctg(180-?1);W= B+K*(n/2-1) When the numbers of chair leg is more than n and K≤H,length and width formulas of splicing board: L=2D+B/ctg(180-?1);W= B+H*(n/2-1) When K≥2AH/ [2D+B/ctg(180- ?1)], use the fist of combination.(2) The entire arc chair leg's best splice formula: When the entire arc chair leg is a reducing socket, length and width formulas of splicing board: L=A+l,W= B+ H (n-1)When the sizes of both sides of entire arc chair leg are close, length and width formulas of splicing board: L=A;W=B+H(n-1)(3) The multi-arc chair leg's best splice formulas: L=A;W=B+H(n-1)(4) The straight line chair leg 0234 chair legs increase utilization by1.67%; 0618 chair legs increase utilization by 14.76%; 0608 chair legs increase utilization by 1.04%.
