Kinematics performance simulation and optimization of large face-shovel hydraulic excavator working device based on ADAMS

In order to study the influence of key hinge point's positions to the kinematical performance of the face-shovel hydraulic excavator working device, a forward kinematics model of the working device is presented firstly. And then the simulation model is established in ADAMS. The working processes are simulated and the bucket digging envelope diagram is drawn. Then different simulation models in ADAMS are established by using Monte Carlo method to sample data which are the range of key hinge point's position. According to a certain order and requirement of objective response, the model with better motive performance can be chosen. The results show that the chosen model has better kinematical performance than that of the initial model where all of important objective responses can be improved differently.
