Mechanical property analysis of the boom considering large deformation effect

摘要

Finite element analysis on the strength and stability with the full extension job is researched for some special truck crane. The different telescopic parts are connected by the slider, which can transfer load through mutual contact and deform. Stress concentration always appear with the traditional method, so the contact algorithm is vital to the simulation. The intensity and stability of the boom is simulated with finite element analysis with the degree coupling technology, the simulation results have significance for further optimal design of the boom.
