利用Inventor软件对采煤机扭矩轴进行参数化建模,通过控制扭矩轴模型卸荷槽的二次曲线形方程参数,进行线性应力分析得到合适的扭矩轴卸荷槽开口形状。针对此参数下的模型进行模态分析,得到扭矩轴的固有振动特性,结果表明采煤机的扭矩轴工作时不会发生共振。 Inventor software was used to parameterize the shearer torque axis. By controlling the parameters of the quadratic curve equation of the unloading trough in the torque shaft model, linear stress analysis was performed to obtain the appropriate shape of the opening of the unloading trough for the torque shaft. According to the modal analysis of the model under this parameter, the inherent vibration characteristics of the torque shaft are obtained. The results show that the resonance of the torque shaft of the shearer does not occur during operation.
