| Abstract: | A detailed automotive hood model is built with Abaqus, an explicit dynamics simulation on the close process of hood is performed, and the stress response of hood during vigorous close process is researched. The local strain of hood is tested and compared with the simulation results. The results show that the method is accurate to forecast the transient stress response of hood during close, which can guide the strength and durability design of hood. |
