Puma I5 Diesel Engine Oil Pan Assembly NVH Optimization with Optistruct and AVL-Excite 2008-01-2721

Comfort ride appears as one of the challenging factors in today's competitive automotive sector. Noise level of the vehicle is an effective parameter for the comfort demand of the customer. Oil-pan is the component which transmits structural borne excitations from engine block to air. Improving the NVH performance of the pan by adding beads is a low cost approach and does not increase the mass. Aim of this study is to improve the stiffness of the Puma I5 engine oil pan assembly and to obtain satisfactory improvement in noise levels while keeping the mass of the oil-pan constant.
