调平技术研究及在工程机械上的应用

Study on leveling technique and its application in the engineering machinery

文章介绍了一种同步调平方法,该方法采用双闭环控制技术,流量控制与角度反馈相结合,使用此方法的支腿式工程机械,易于实现所有支腿同时控制与各个支腿单独控制,并且可以适用于不同负载、不同起升高度要求下的同步性调节,控制平稳、精度高,调平速度快。

This paper introduces a synchronous leveling method,the method adopts the double closed loop control technology,flow control and the combination of angle feedback, using the method of leg type construction machinery, easy to implement all of the leg and each leg separately controlling at the same time, and can apply to different load, different lifting height under the requirement of synchronization adjustment, stable control, high precision and fast leveling.
