Abstract:

In this paper,the saw-timber's analytical model was applied.Considering the bending curvature,the optimal design for improving recovery ratio was applied to making bending wood and the mathematical model was initialized.Because this saw-timber's model is the optimal models based on continue analytical saw-timber model,which precise is better than traditional way's.The objective function is from continue function,especially with the analysis of continue function,every parameter's effect to optimal design is worked out,and these parameters are superior for initialing the optimal objective function and considering the best answer to the function with optimal designing,which is complied with in the industrialization of bending wood.

Key words: bending wood, mathematic model, recovery ratio
