| Summary: | 碩士 === 華梵大學 === 機電工程研究所 === 94 === Since the long time, the noise and vibration always speaking of the equipment of diesel engine generator is a very major problem. Therefore how improves is an important work is at. This research uses specification of the 125KW take the Taiwan railway of Nan-Kang temporary station which TATUNG Corporation produces as the simulation object.
At first, we draw up the 3D full-scale mockup by commercial CAD software – Solid Works. We transfer the files to dynamic simulation analysis software – ADAMS. To simulate the generator start, it correlates with spare part the relative motion.
We approximately divided into four parts in the simulation part. The first part for aims at generator several items of important spare parts to carry on the characteristic measurements. The second part for aims at situation of the generator actual operation to carry on the simulation analysis, in view of vibrates the influential several items of parts in the simulation process with the generator the characteristic parameter to carry on the adjustment like rotor, the dumping coefficient to carry on the dynamic simulation. The third part the generator rotor for separately identical plane and not the identical plane hypothesize eccentric amount carry the imbalance amount simulation analysis. The fourth part carries on the natural frequency to the generator rotor the analysis. Penetrates this research to be able to utilize the CAD software and the function of ADAMS dynamic simulation, can promote the ability of research and development design.
Key words：natural frequency、KW
