采煤机锥套强度分析及优化

Strength Analysis and Optimization of Shearer Cone Sleeve

针对采煤机锥套时常发生压溃问题,对锥套强度进行了理论分析并给出了锥套优化的方向,利用有限元法对现有锥套和优化后的锥套进行对比分析,发现现有锥套端部应力较大且超出材料屈服强度,而优化后的锥套端部应力较优化前降幅可达80%以上,优化效果明显。

Aiming at the problem that the shearer cone sleeve is often crushed, the strength of the cone sleeve was analyzed theoretically and the optimization direction of the cone sleeve was given. The finite element method was used to analyze the existing cone sleeve and the optimized cone sleeve. It was found that the stress at the end of the existing cone sleeve is large and exceeds the yield strength of the material. The stress at the end of the optimized cone sleeve is reduced by more than 80% compared with that before optimization. The optimization effect is obvious.
