针对油门踏板在轮式挖掘机上的应用,提出了一套可靠的轮式挖掘机行驶速度的控制方案,详细介绍了油门踏板信号的采集及其对行走比例阀电流的控制策略。试验证明本方案及控制策略能满足轮式挖掘机在实际工作中的应用。
Aiming at the application of gas pedal on wheeled excavator, a reliable control scheme of the traveling speed of wheeled excavator was put forward. The gas pedal signal acquisition and its control strategy on walking proportional valve current were introduced in detail. The test proves that the scheme and control strategy can meet the application of wheeled excavator in practical work.
