| Hybrid system is a novel energy form compared with the engine.The new drive mode of individual drive,has been successfully applied in the car.The system can make the car engine,in most cases,working in high efficient area,and can use battery storage capacity to brake the car when braking energy and downhill when the potential energy stored.Meanwhile,at the right time it can output instead of a gasoline engine driving load,thereby significantly reduce automobile fuel consumption,reduce emissions,save the cost.Because of these advantages,many hydraulic excavator manufacturers and research institutes have been looking for the application of the hybrid power system in hydraulic excavators and other construction machinery on the related technology,continue to explore and perfect the technology.This topic considering the performance of the hydraulic excavator,the hybrid technology application in power system,how to match the best structure parameters and design to study the control strategy,to increase the work efficiency of hydraulic excavator,the purpose of reducing its energy consumption and emissions.The research content includes:(1)Discuss the research of construction machinery and its hybrid energy system value,expounds the conditions and orientation at present in China and overseas to study,and described the construction research of the key skills of mechanical hybrid energy and use prospect.(2)Compare three kinds of strategies of hybrid energy control system,the combination of attributes of the construction machinery,in order to confirm the use of countermeasures is parallel architecture,and the engine and the motor dynamic energy parameter collocation.(3)The formation of hybrid energy system using Matlab/Simulink module and on the implementation of simulation analysis,and the use of multi operation control measures,through all kinds of basic attributes of different system analysis proved that the hybrid energy system stable operation and cheap oil. |
