This paper deals with loosening performance of bolts of transmission towers under low frequency vibration. To evaluate the loosening performance, 30 transverse tests for bolted joint are issued, whose frequency ranges from 1 Hz to 3Hz. The results show that double-nut bolts feature better loosening performance than single-nut bolts, and the loosening performance decreases along with the incensement of vibration frequency.
