| Abstract:In view of the increasing attention paid to the vibration and noise requirements of marine diesel engines, and the fact that the quotas are still non-standard, non-systematic or even wrong conceptually,the relevant national and marine industry standards were systematically collated.The differences and contradictions between varied quotas and standards were compared based on the performance evaluation requirements and engineering practice, and some conceptual and conventional understanding errors were pointed out and corrected. The analysis focused on the relevant test methods, limit values and evaluation criteria, clarified the logical relationships and technical map of each performance quota.It is pointed out that the existing standards need to be improved and perfected, and suggestions for the choice of these standards in the current engineering application were put forward. The research provides the basis for the construction and further improvement of the marine diesel engine vibration and noise standard system. |
