With the increasingly serious problems of energy shortage and environmental pollution, people's increasing awareness of environmental protection, and the increasingly strict restrictions on energy consumption and exhaust emissions of construction machinery at home and abroad, the development of environmental protection and energy-saving products has become the development trend of construction machinery. In view of the successful application of hybrid technology in automobile, in recent years, famous construction machinery manufacturers at home and abroad turn their research and development to hybrid system, which has become one of the important research directions of energy saving and emission reduction of construction machinery. The research and development of a powerful hybrid hydraulic excavator simulation test bed plays an important role in the research and development of hybrid construction machinery.
