It has been proved that oil cooler cover is a main source of surface radiated noise for engine. And the existence of cooling liquid has a great influence on the vibration of oil cooler cover. Taking the fluid pressure as pre-stress and using the liquid-solid coupling method, a liquid-solid coupled model is established and used to predict the vibration and radiated noise of plastic oil cooler cover firstly. According to the prediction results, the main coupling modal frequencies that have great contribution to the radiated noise of the plastic oil cooler cover are identified. Then the multi-objective optimization is applied to structure topography optimization using the exponential weighted method. Compared with the initial plastic oil cooler cover, it has a higher performance: the overall noise is reduced 1.79 dB.
