| Abstract: | Analyses for one vehicle diesel block and oil sump dynamic properties were carried out by experiments and FEA, and the natural frequencies and modes were obtained. The main excitation forces and structure responses were also discussed, and the optimization tendency was presented. This investigation paves the way for the further NVH(noise vibration harshness) analysis. |
