| Abstract: | In order to realize the intelligent control of Model WY 1.5 Hydraulic Excavator,a modification is made on the original hydraulic system of the excavator with application of the electro-hydraulic proportional control technique on the basis of not remodeling the function of the original;for which a design scheme of the electro-hydraulic proportional control is put forward and the selecting principle for both the electro-magnetic change-over valve and the electro-hydraulic proportional change-over valve is described herein.The working performance of the modified system is demonstrated to be stable through the experiment concerned and then provides a reliable platform of the electro-hydraulic system for the study on the intelligent excavator. |
