Abstract
Aiming at the shortages of low efficiency and large fuel consume of a truck-mounted concrete pump, a global power matching method are proposed based on both fuel consume rate of the engine and efficiency of the hydraulic pump. The combination optimization on fuel consume rate of the engine and efficiency of the hydraulic pump are realized by genetic algorithm. The control objects, as far as the rotating velocity of the engine and the displacement of the hydraulic pump, can be adjusted at the same time and follow with the load adaptively, resulting in that all the components working at high efficiency region. The comparative experiments are tested with the new and old methods. The results showed that the new one was superior to the old. The average energy save ratio is 16%.
