Abstract Nowadays large-sized hollow closed-end section bar is widely used in aluminium-alloy car body for Metro with certain complex structure. It is necessary to establish finite-element model and make static analysis to aluminium-alloy car body in order to simplify calculation process. The static and dynamic calculation results of two types of models are compared under the same boundary and load in this paper, through establishing finite-element model with two different types of units (solid45 and she1163)to aluminium-alloy car body. It is concluded that adopting lamella unit can reduce unit quantities greatly and increase the network quality on the premise of meeting the accuracy requirement, with the feature of saving calculation cost. It and optimising calculation to aluminium-alloy car body.
