摘要
结合交流变频电机的能耗制动原理和钻机下钻特点,对92A钻机下钻运动学与动力学进行分析,掌握了下钻的运动规律和绞车滚筒上的载荷变化情况,规范操作手的操作,校核绞车刹车的安全系数。
Combining with dynamic braking principle of AC variable frequency motor and char- acteristic of drill down, the paper analyze kinemat- ics and dynamics for drill down of 92A drill, obtain motion law of drill down and load variation on roll-er of winch,which direct operation of operator and check safety factor for brake of winch.
