Abstract:

Taking a heavy truck cab as the example, a model of  the spotweld space based on finite element  was built to analyse the torsional stiffness of the model, and the amount and layout of the spotweld using the discrete variable topology optimization were optimized. Comparing with the original model in welding spot's number and the torsional stiffness, the optimized model has less number of welding spot, but the torsional stiffness of the two model is almost the same. So the method of topology optimization has guiding significance and great value on the spotweld layout.

Key words: vehicle engineering, cab, welding spot, topology, optimization, FEM
