Research and Application of the Structural Optimization Design Technique for the Large and Efficient Band Sawing Machine

This paper takes the large band sawing machine GB42500H as the research object, and establishes the dynamics models of its various parts. Respectively, the relative research is done from the theoretical modal analysis and the dynamic performance testing. According to the analysis results, the structure or geometry improvement scheme of the parts is proposed. The paper also studies preliminarily the dynamic characteristics of the large band sawing machine GB42500H. During the analysis, the models of the parts and the whole are established using the finite element method to optimize the structures of the parts and the whole. That has undoubtedly a very important significance for improving the dynamic performance for the new machine tools structure, increasing the processing accuracy, and shortening the development cycle and costs.
