Mechanics for the environmental impact of a vehicle platform suffered outside,improve electronic equipment vibration resistance and other issues, study on Electronic Equipment vibration system theory, the dynamic differential equations by the shock absorber layout,analyzes the situation is different vibration coupling layout mode,completing the damping system design. According to the mechanical response of the external environmental parameters for electronic device structure random vibration analysis and shock. Verification and analysis to verify the validity of the damping system by finite element method. The results showed that,based on a complete vehicle platform damping system to improve electronic equipment vibration resistance.
