本文在对四缸柴油机试验的基础上,参照国际标准和国内情况,对国产中小功率柴油机的振动评价作了探讨,认为以当量振动烈度作为评价标准是可行的,并提出了几点补充建议。 Based on the test of four-cylinder diesel engine, this paper discusses the vibration evaluation of domestic small and medium-power diesel engines with reference to international standards and domestic conditions. It is feasible to use equivalence vibration intensity as the evaluation standard, and some suggestions are put forward.
