Construction and Evaluation of Database on Rotary Blade Arrangement for Rotary Tillage

Abstract

A Pareto optimum database compling feasible blade arrangements for rotary tiller design, was constructed using a dynamic programming approach under practical constraints. An algorithm for programming was developed to construct the database. As the result, the performance provided 31 kinds of rotary blade arrangement patterns based on the number of rotary blades from 12 to 40 in the database showed that some arrangements were superior to the commercial rotary shaft in terms of seven items for evaluating the tillage performance of the rotary shaft.
