| Abstract: | Rational design of power system units’ parameters can meet the requirements of hybrid excavator power performance and operation performance It also can decrease the installed powers of power system units.The process of energy transfer of hybrid power system units’ is analyzed.The action law of diesel engine output power with installed powers of power system units is obtained,which is used to drive load directly.Installed power design method of excavator hybrid power system units is proposed and calculation equations of power system units’ installed power are proposed.Installed powers of 7T excavator power system units are calculated.Calculation results show that the proposed method can realize calculation of installed power of power system units and the method can be used to hybrid power system with different structures. |
