Abstract

Abstract: In this paper, in response to the lightweight design requirements of the truck crane boom, a jib boom with a sandwich structure of carbon fiber reinforced plastic and balsa wood for a truck crane is designed. Carbon fiber reinforced plastic is an advanced material with excellent mechanical properties such as low density, high specific strength and high specific modulus,which can reduce the quality of parts. The finite element software ABAQUS is used to carry out structural design and simulation analysis on the jib frame of a truck crane with a carbon fiber composite balsa sandwich structure. The research results show that the thickness of the upper and lower panels of the carbon fiber composite material in the balsa sandwich structure jib frame is 10 mm and 8 mm respectively, and the upper and lower panel plies are [0/±45/0₂]₁₀ and [0/±45/ 0₂]₈. Compared with the carbon fiber reinforced plastic jib frame, its strength has a larger safety margin, and its rigidity also meets the needs of use. At this time, the weight of the jib frame of the sandwich structure of carbon fiber composite material and balsa wood is 251.4 kg, and the weight is reduced by 40%, which has a good lightweight effect.

Key words: truck crane jib, lightweight, CFRP, balsa core structure
