| Abstract: | A study has been carried out on the fracture problem of the body framework of certain typed frontier defence patrol vehicle arisen in the reliability road test.On the basis of the analysis on static torsional loading and modality of the finite element model of the original prototype vehicle,combining with the main reason of body framework fracture determined by the actual condition of experiment,a proper modification was worked out on the original model by the use of topological optimization.Thus made the being designed body framework structure more reasonable,and the third road test of this vehicle has been favourably passed.Rather better effect has been gained for its every performance index. |
