Dynamics Simulation Analysis on Hydraulic Excavator Working Mechanism Based on Rigid-Flexible Coupled Modeling

Hai Song Shi, Lihua Wang, Zhu Yang, Peng Cheng Wang

Abstract

Taking a type excavator as an example, three-dimensional model was established using CATIA software, using the ADAMS software to the dynamic simulation analysis; get the movable arm hinged point load curve. The maximum load into ANSYS finite element analysis was carried out on the derrick structure, derived from ANSYS MNF file imports ADAMS to get the coupled model and dynamics analysis, get the time-varying curve working device. Results show that the coupled model is more in line with the actual, work can be more fairly reflect device performance, can provide the basis for further optimization of the structure of excavator.
