Abstract：Based on the mechanics simulation software AMESim, the model of pressure annunciator and its experiment system
was established. Considering the relative motion between valve’s moving parts and its shell, the viable interface form of vibration
environment and the simulation model through theoretical analysis. Then a new model of the pressure annunciator in vibration
environment was given, and the simulation results were highly dovetailed with those of experiment. Research on the mechanism of
false triggering was made by using the new model, and the solutions were present in the end. Study in this paper supplied feasible ways
and means for simulation of characteristic of valves in vibration environment.
Key Words: Pressure annunciator; Vibration environment; AMESim; False triggering
