Large Pendulum Bolt Failure Analysis and Countermeasures

Abstract:

This paper analyzed the causes of the bolt failure problem of pendulum for different working conditions using the finite element method. The simulation shows that the bolt fracture is due to relaxation caused by bolt slewing bearing and a flange partial slip on .The cause of the failure was the structure design lacking of effective anti-loosing measures. Finally, this paper put forward an effective design scheme to prevent bolts from damage during working process and proposed the specific measures and bolt failure countermeasures.
