The Finite Element Analysis of the Boom of 20-ton Backhoe Hydraulic Excavator Based on ANSYS

Abstract

Taking the boom of 20-ton backhoe hydraulic excavator as the research object, this paper analyzed the strength of the boom by ANSYS software, simulated the load condition of the boom under the bucket excavation condition, and obtained the stress distribution cloud diagram of the boom. The analysis results show that the stress of the boom of the excavator is mainly concentrated on the hinge of the boom and the stick cylinder, which is the weakest link.
