Initiative Research Of Design Optimization For Vehicles Structural Parameters

This paper briefly introduces the basical principles of finite element method which can be used for analysis of vehicles structure,describes the principles and methods of design optimization for vehicles structure parameters,establishes the finite element models of semi-dragging trucks,which is used to load cement dispersedly and container semi-dragging trucks,applying the ANSYS software,calculates the static strength,then proves the calculation results to be accurate by means of non-electric charge surveying experiment.At the same time,the author puts forward the model and methods of optimization design for structure parameters of vehicle frames,exploits the applied software of semi-dragging trucks,does optimization design .analyzes the feasibility of the optimization results,then gives the structure improve direction .Besides this,the author has had initiative research about interface software,etc. and furnished the basis for solving the data interface and parameters problem between MDT and ANSYS.The models and methods of brunch optimization design of multi-variables for vehicle structure parameters that the paper has put forward has some theory significance and applicable value.
