Modeling and Simulation of Hydraulic Excavator Based on Virtual Prototype

Hydraulic excavator plays a significant role in the modern engineering, it was bored complex and changing work stress and strain, its structural strength design directly affect the performance and reliability of the excavator. The virtual prototype technology can simulate all kinds of working conditions and achieve the ideal effect by optimizing parameters. In this paper, the 3D modeling of a hydraulic excavator was established using the Solidworks and converted into ADAMS software environment, added the constraints, the drives and loaded epigenetic reasonably and generated the main working parts of the virtual prototype model. The limit work trajectory displacement graph was given, and we obtained the change characteristic curve of the hinge point of the force at work. The static strength was analyzed by the finite element model in ANSYS, the stress and strain nephogram of the working device show that the reasonableness and correctness of the design, it provides a convenient and efficient means for the excavators design and optimization.
