新型薄煤层采煤机截割部建模与仿真研究

Abstract

A virtual rigid-flex coupled prototyping of a new type shearer cutting unit for thin coal seam from a company is established in the co-simulation platform based on PRO/E、MATLAB、ANSYS、ADAMS and NSOFT,the stress and strain condition of the key parts of the cutting unit are obtained by dynamic simulation,and Found that the local of shell and planetary carrier exist a larger dynamic stress,the optimized shell and planetary carrier stress are more evenly distributed,significantly improved mechanical properties;fatigue life analysis of the output shaft are launched afterwards based on NSOFT,the weak link prone to fatigue damage was found.The results of the analysis provides a quantitative basis for the performance improvements and structural optimization,and the design cycle can be shortened.
