Abstract:

The vibration failure mode and weak links of the inch relay through vibration test were analyzed.An Ansys-based anti-vibration finite element model was established to perform modal analysis verification and key part response force analysis.Combined the basic ideas of anti-vibration design and transfer path analysis of vibrational excitation,the anti-vibration design of the relay was given out.It is verified that the anti-vibration design has a significant effect on improving the anti-vibration performance of the relay through simulation analysis and testing.

Key words: relay, finite element, model analysis, responsive force
