The basic train of thought for the research and development of small-sized sugarcane leaf peeling off machine was expounded. The method of virtual prototype technology combined with experimental modification was adopted for the design of leaf peeling off machine. Firstly, motion mechanism for the peeling off of sugarcane leaves was analyzed according to functional requirement of leaf's peeling off, and then the overall scheme of leaf peeling off machine was decided preliminarily. The design of leaf peeling component—kernel element of leaf peeling off machine—is an optimal designing problem with multi-factors and multi-targets. By adopting virtual analytical designing method based on orthogonal experiment and utilizing large-scaled statistical software SPSSthe regression analysis was carried out upon the experiment, thus the optimum parameters of leaf peeling component were found rapidly and effectively. Through assembly of the whole machine, simulation analysis and modification upon the experiment, the digitized mdoel of product leveled leaf peeling off machine was obtained.
