Finite-element analysis of deflection mechanism of small-size excavator

The design of the deflection mechanism of GC18 excavator was studied in this paper.The three-dimensional model of the deflection mechanism was established with Pro/Engineer,and some simulation assemble and finite-element analysis which was used to calculate the stress and transformation of two typical working positions on the deflection mechanism.The conclusion serves to provide technical references to the design of a new excavator model.
