Abstract: Aiming at the performance matching problem between the working attachments and the hydraulic system of face-shovel hydraulic excavator, the multidisciplinary collaborative simulation method was proposed, and which was applied to performance studies of the whole engine system simulation. To accurately simulate the change to the performance parameter of each subsystem in the work process of the hydraulic excavator, the working attachment mechanism simulation model was built based on the multi-body dynamics simulation software ADAMS, and the modeling method of the digging resistance was put forward by using extended discrete element method (EDEM) software. Then, according to the hydraulic system principle and the control mode of the hydraulic excavator, the integrated simulation model, with the compound control pump, was established by using main simulation platform AMESim. Through the performance parameter of the hydraulic main pump and the hydraulic cylinder were validated in the whole operation cycle of the hydraulic excavator, the influence of the hydraulic system performance in different digging resistance load was analyzed. The results indicate that it is an effective and accurate method for modeling complex systems. And the rationality of the matching performance parameters of the designed hydraulic system is validated with the multidisciplinary collaborative simulation method.
