| Abstract:Along with the marine main engine development trend of high explosion pressure, long stroke and low speed, there came the problem of excessive vibration in main engine bench test. Taking MAN 6G70ME-C as an example, certain vibration performance was measured and studied, and an easy and economical vibration avoiding method was introduced. This method was proven to be effective, which ensured the safe operation of the main engine. |
