Abstract: Based on the principle of work foundation of double frequency electric generator of a power supply vehicle, the paper carried on the analysis on the reliability and calculated the “Mean time between failures” of the electric generator. Further analysis indicated that the actual reliability level of double frequency electric generator will be higher than the predicted value.
Key words: double frequency electric generator; reliability; mean time between failures
