工程机械动力系统节能控制策略

Energy Conservation Control Strategies Regarding the Power System of Engineering Machinery

对工程机械动力系统进行节能控制，必须在减少液压系统能量损失的基础上，在保证供油流量和 作业功率的前提下，考虑发动机功率的合理利用．以此为出发点，提出了液压系统变量泵排量和发动机运行工况按“理想节能控制特性”进行联合调节的节能控制策略．

In regards to the energy conservation control of the power system ofengineering machinery, due considerations should be given to the reasonableapplication of the motor power on the basis of reducing energy losses of thehydraulic system and gUaranteeing the oil supply flow rate and operating power.Grounded on this point, this thesis puts forward energy conservation strategieswhich serve to undertake uniform adjustment for the variable pump displacementsof the hydraulic system and motor working conditions in line with the 'idealenergy conservation control characteristics'.
