Abstract:

Facing the matters about structural parameters design of missile-borne electronic equipments double-layer vibration isolating system, the laws that how the frequency ratio, mass ratio and damp ratio of the 2rd layer vibration isolating system to the 1st layer vibration isolating system affecting acceleration response and displacement response of electronic equipments under shock response spectra excitation are studied, and some universal conclusions are drawn. The conclusions can be used to direct the design of double-layer vibration isolating system for well shock-absorption
