全液压推土机速度控制系统的研究

摘要

分析静液压传动的原理，提出速度控制方法和控制策略，开发出全液压推土机的控制系统，进行了台架和实车实验。实验结果表明：提出的速度控制方法能有效地保证推土机的微动性能，且操纵简单，系统响应快，极大地降低了劳动强度。%The principle of fully hydraulic drive was analyzed.The speed control method was proposed.The control system and control strategy were developed.The rig test of vehicles and the bulldozer test were done.The experimental results show that the speed control method can effectively guarantee the micro performance of the bulldozer,the control system is simple and fast,it can greatly re-duce the labor intensity.
