Abstract
The deformation of a TVM's body frame was calculated and the structural FEA (Finite Element Analysis) was accomplished in this paper. The geometric model and finite element model of TVM (Ticket Vending Machine) were built. To locate the maximum stress and displacement precisely, structural analysis of the TVM's body frame under its gravity was analyzed by FEA software. The results indicate that the maximum stress appears at the front welding joint on the underside edge of the left panel while the maximum deformation is located at the right welding joint on the front beam. Based on the analysis results, different structure improvement measures have been put forward to reduce the deformation.
