Design and Analysis of Power Head of Full Hydraulic Tunnel Drill based on Function Analysis Method

为进一步提升分体式全液压坑道钻机用动力头的性能,运用功能分析法提出一种新型的动力头传动系统。采用ADAMS、ABAQUS联合仿真方法,研究了钻机最大负荷时新型传动系统的非标准齿轮齿面的接触应力,并与赫兹接触理论的数值计算结果进行了比较。分析表明:全液压坑道钻机在运行过程中,最大转矩2866N·m;最大啮合接触力为3455N,最大等效接触应力为889MPa;理论计算与有限元分析的最大应力误差为3.6%,该设计方案能满足钻机的需求,为钻机动力头进一步的优化分析奠定了基础。

To further improve the performance of the power head of the split type full hydraulic tunnel drilling machine,a new power head transmission system is proposed on the function analysis method.Using ADAMS and ABAQUS joint simulation method,the contact stress of non-standard gear tooth surface of the new transmission system under the maximum load of the drilling rig is studied and compared with the numerical results of Hert.contact theory.The analysis shows that the maximum torque is 2866N·m,the maximum meshing contact force is 3455N,and the maximum equivalent contact stress is 889MPa.The maximum stress eror of theoretical calculation and finite element analysis is 3.6%.The design scheme can meet the needs of the drilling rig and lay the foundation for further optimization analysis of the drilling rig power head.
