The Application of Parametric Method in the Vertical Boom Structure Analysis of Bridge Inspection Vehicle

The vertical arm of bridge inspection vehicle has a complex structure. During the finite element analysis, it is difficult to change parameters and easy to make mistakes for finite element model of vertical boom. In order to simplify the analysis process and save modeling time, A professional mechanical CAD software is developed for secondary development of HyperMesh to realize the input design parameters and output HM command stream. Then, the finite element model is established automatically by using HyperMesh to execute the HM command. And the Optistruct solver file is output. The Optistruct solves the file and outputs the analysis results. Finally, the parametric method is applied to the vertical boom analysis of bridge inspection vehicle.
