Vibration characteristics of contact system have effect on the reliability of switching electrical apparatus, such as
electromagnetic relay and contactor, that working in the mechanical environment greatly. According to the typical features of
contact system, the non-linear vibration characteristics of a linear beam with cantilever-Hertizian contact boundary conditions
were investigated in this paper. The mathematical models of beam structure vibration are presented by forth-order partial
differential equation, and the semi-analytic solutions were obtained by using the method of multiple scales. One primary result
from this analysis is the amplitude–frequency relation for the various flexural modes. The softening behavior of
amplitude-frequency is investigated by varied parameters including, initial contact force, damping coefficient, excited force
and mass of contact. Different normal modes of contact system were solved explicitly. The results show that the method is
more suitable for nonlinear dynamics analysis of contact system in electromagnetic relay. |
