液压挖掘机功率匹配与动力源优化综合控制策略Control Strategy of Power Matching and Power Sources Optimization for Hydraulic Excavators
液压挖掘机 功率匹配 混合动力
2009/5/18
现有的液压挖掘机功率匹配方法由于负载工况的剧烈波动和不可预知性，导致动力源工作点很大部分分布于高油耗区域，动力源本身效率无法得到提高，从而影响了整机效率。为此，提出了一种基于混合动力技术的液压挖掘机全局功率匹配与动力源优化的综合控制策略。该策略以传统功率匹配方法为基础，结合混合动力的特点，在实现动力源、液压泵和负载三者功率匹配的同时，优化动力源的工作点，提高整机的燃油经济性。试验表明采用该策略的液...
