Vibration Modal Analysis of the Upper Frame of Hydraulic Excavator

Abstract:

As the upper frame is an essential supporting structure of Hydraulic Excavator, dynamic characteristics of the structure are particularly important. The finite element model of the upper frame is established by the finite element analysis software, and then modal analysis is carried out in absolute freeness. The former fifteen modes are adopted to review its inherent frequencies and vibration modes seriously, and the dynamic characteristics of the frame are clear. Analysis result indicates that there are some weak links in the structure, and suggestions of modification are put forward for the further structure improvement.
