Abstract:

The two methods of making rectangle_section curve woods were bending shape process or milling, which was analyzed in this paper. The difference of fibrin distributing and the variety of strength that caused were explained. The material mechanical theory was used to the numerical analysis of curve wood strength. The bending wood was stronger than milled curve wood,which was improved by the theory in this paper.With the curvature's increasing,the strength difference between them was greater.According to this theory,the strength difference of bending wood and milled wood was worked out by several parameters.In the application of curve wood,the theory of strength analysis was provided.

Key words: curve wood, mill, strength, shape process
