Automated Finite Element Analysis Method for Excavator Boom

In allusion to the deficiencies existing in current structural finite element analysis of excavator boom such as the intense manipulation strength and the inefficiency of the modeling, the operation mechanism of automated structural finite element analysis of excavator boom is researched based on the Pro/TOOLKIT, APDL commands and the ＂Batch＂ operation mode of ANSYS. Then the architecture of the automated structural finite element analysis system of excavator boom is established and the work procedure of the finite element analysis is proposed. As the excavator boom with two boom cylinders is taken as an example, automated structural finite element analysis software of excavator boom is developed to demonstrate that the automated structural finite element analysis method is feasible with effectiveness in improving the batch structural finite element analysis modeling of excavator boom.
