Abstract

The dynamic model of a high-speed circuit breaker mechanism with a spring-actuated cam is derived, and its validation and appropriateness for an analysis of high-speed motion behaviour are checked through experiments. In particular, the characteristics of the friction on the camshaft are investigated using the non-linear pendulum experiment. The parameters of the friction model are estimated using an optimization technique. The analysis shows that the friction of the pendulum depends on stick-slip, the Stribeck effect and viscous damping. The simulation results of derived dynamic models for the rapid closing and opening operations are compared with actual responses using a high-speed camera and are investigated to validate their usefulness. The spring motion, which has much influence on the closing responses, is observed.
