| Abstract: | The vibration of the oil pan is the main source of the engine noise, and it is very useful to take an optimization for the oil pan. There are not study on the vibration performance on topology and shape optimization. The bead optimization on the oil pan is performed by Tosca considering the vibration velocity of the oil pan surface. The results show that the performance of optimization design is improved much, and the bead optimization technology can fully develop the structure potential. |
