improvement of the power transmission mechanism to aircraft refueling pump By vibration analysis technology

Abstract

This paper deals the measurement of vibrations in mechanism of power transmission to the aircraft fueling pump with high productivity.Vibrations analysis technology was used to determine the vibration parameters in the internal parts of the base model at this mechanism and their impact on the defects in it from the design and technical point of view. In order to increase reliability and reduce vibration parameters during investment, a design modification of the power transmission was made in the base model, including the addition of an auxiliary gearbox and a power take off unit, and the length of the cardan shaft to the pump was reduced. The results of the experimental study of the modified model of power transmission mechanism to the pump showed a significant decrease in the speed and frequency of vibration compared to the base model.
