Abstract


The competition of vehicle industry is fierce increasingly. Being able to develop new products or not is the key point in the competition. As the definite indication of vehicle body modeling and the important carrier, vehicle body engineering, the external evaluation model of vehicle plays an important role in the procedure of advanced design and manufacturing of vehicle body. The model frame guarantees the stiffness and strength of model. The frame which is of reasonable structure and excellent capability is good for prolonging the service life of vehicle model and decreasing the possibility of model repairing and redoing. In the past manufacturing technics, the design of vehicle model frame relies on the design experience. The frame shape and layout is designed according to the body contour. Such a designing procedure may be inefficient to some extent.The topologica1 optimization method of continuous structure is imported in the design of vehicle model frame in the paper, making the reasonable space distribution of materials under special loads and restrictions definite. The frame layout project could be decided according to this. Firstly, the vehicle external evaluation model and manufacturing technics are introduced in the paper. Secondly, the development, basic principle and solving method of the topologica1 optimization theory are introduced, constructing and deducing the model of the topologica1 optimization algorithm of variable density method. Then the load of vehicle external evaluation model is considered under the condition of milling, transportation or wind tunnel test. At last, the software HyperWorks is used for vehicle model topologica1 optimization to obtain the best layout of vehicle model frame. According to the layout, the profiled bar jointing technics and the practical machining situations, the frame could be designed.The analyzing results indicate that the frame designed by this method satisfies the design requirements basically. Applying the topologica1 optimization method for vehicle body frame design can improve design efficiency and shorten the lead time significantly.
