Hydraulic Excavator Boom Lightweight Design

Abstract:

Regarding 20 tons hydraulic excavator boom in an enterprise as the research object, the boom volume was set as an optimized object. According to the dynamic simulation analysis of working device in typical working conditions, constraint conditions including the maximum stress, displacement range and thickness variable ranges of each steel plate, were determined, and the thickness of twelve primary steel plates of boom were selected as design variables. A lightweight design scheme has been developed through the optimization module in ANSYS software, which could decrease the boom weight by 9.7% and the strength and stiffness of optimized boom structure also met the design requirements.
