本文提出计算内回转凿岩机扭力矩的新方法。文中指出,活塞在回程时有很大的运动加速度,因而在计算凿岩机扭矩时必须考虑惯性力的影响,并用动静法导出了扭矩计算式。
This paper presents a new method for calculating the torsional moment of an internal rotary rock drill. The article points out that the piston has a large acceleration during the return stroke. Therefore, the influence of the inertial force must be considered when calculating the rock drill torque, and the torque calculation formula is derived using the dynamic-static method.
