Statistical Estimation of Vibration Environment for a Certain Aero-engine
Objective The statistical estimation method of vibration environment was studied, which was applied to the condition that the vibration data PSD of aero-engine obeyed lognormal distribution incompletely in the whole frequency bandwidth. Methods Based on the lognormal distribution test of the vibration data, a method was used combining normal tolerance limits and non-parameter upper limits. Results The results of this method were between the traditional normal tolerance limits and the non-parameter upper limits. Conclusion The comparison results showed that this method was reasonable and feasible for determining the vibration environment for aero-engine.
