Abstract

In order to optimize the structure of the pick cutter under the premise to meet its performance, and to achieve their own weight, the pick cutter of the longitudinal axis roadheader, which works under complicated seam conditions, is regarded as the research object. Based on the finite element method, statics strength analysis and fatigue life analysis of pick cutter are finished. According to the analysis results, the arbor of pick cutter is regarded as the object for topological optimization based on the variable density method. For the optimized structure, the necessary analysis is finished to verify its strength and fatigue life. The result shows that the optimized pick cutter satisfies the requirements with 24% weight reduction. It provides some reference for structure design, improvement and further research of pick cutter, and has a high guidance and practical value.
