Abstract： Aiming at the problem of performance optimization for the working range and the digging force of large face-shovel hydraulic excavator work device，kinematics simulation model of hydraulic excavator work device was developed by ADAMS/view firstly，to obtain the digging envelope diagram and the working range performance，through changing hinge point positions to optimize the working range performance. Then dynamics simulation on the work device dynamics simulation model was carried on，which integrated hydraulic model， that developed by ADAMS/Hydraulics，to research the digging force performance and optimize the biggest digging force by changing hinge point positions. The result indicates that this optimization method is an ideal approach to improve the performance  of the working range and the digging force for the work device. The final optimization plan will become the design basis of research and development of large-scale hydraulic excavator.
