Research on power matching of concrete pump truck based on global system
In order to reduce the energy consumption loss of concrete pump truck,an energy saving control strate-gy is proposed for the fuel consumption rate of engine and variable pump efficiency of concrete pump truck.The models of engine fuel consumption rate and variable pump efficiency are established based on the bench test da-ta,and the control strategy of global system power matching driven by energy saving is studied.In the strategy,the energy saving parameter matching scheme of the global power system based on genetic algorithm is adopted,the speed ratio of the transmission box is set reasonably,the economy of the global system is taken as the optimi-zation objective,and the engine speed and the variable pump displacement are adjusted reasonably,so that the engine and the variable pump can work in the economic zone at the same time.The simulation results show that the new control strategy effectively reduces the comprehensive fuel consumption and has obvious energy-saving effect,which has positive significance for the research of energy-saving technology of concrete pump truck.
