摘要
对某采煤机的扭矩轴进行了设计,通过理论分析确定了扭矩轴的材料、外形尺寸及卸荷槽形式。运用有限元分析软件对所设计的扭矩轴进行静力学验证,仿真结果表明,其最大应力位于卸荷槽处,最大值为618 MPa,仿真值准确度为95%,可以实现过载保护。通过有限元方法得到了所设计的扭矩轴6阶模态,为其使用条件提供了理论依据。
The torque shaft of a certain shearer was designed.Through theoretical analysis,the material,external dimensions,and unloading groove type of the torque shaft were determined.The finite element analysis software was used to verify the statics of the designed torque shaft.The simulation results show that the maximum stress is located at the unloading groove,the maximum value is 618 MPa,and the accuracy of the simulation value is 95%,which can achieve overload protection.The six order modes of the designed torque shaft was obtained through finite element method,providing a theoretical basis for its usage conditions.
