Abstract

Faults and failures analyses consist of a very varied field of technique, so concepts and reliability indicators help us to determine the types of faults easier, their appearance in functioning and mathematical relations for determining the types of failures. Regarding to, the test stands help us to identify accelerated of noises, vibration and serious faults that occur in use and can lead to disposal of equipment, helping engineers quickly find the optimal solutions for most cases. Current methods used to determine agricultural tractors gearboxes reliability are those in open energy flow, they better simulate the real working conditions. We design a gearbox test stand for a rapid noise and vibration reliability diagnoses and tests. Considering the gearbox work conditions and its random possible failures, the stand will be equipped with transducers and a data acquisition system for data collection.

Faults and failures analysis involve a wide variety of engineering areas, so concepts and reliability indicators help us to determine the types of faults easier, their appearance in functioning and the mathematical relations for determining different failures. In this context, test stands help us to identify accelerated noises, vibrations and serious malfunctions that occur during operation and can lead to major equipment failure, thus helping engineers to quickly find optimal solutions in most cases. The current methods used to determine the reliability of the agricultural tractors gearboxes are those in open energy flow, as they best simulate the real operating conditions. An agricultural tractor gearbox test stand was designed to perform rapid noise and vibration diagnostics and reliability tests. Considering the working conditions of the gearbox and its possible failures, the stand was equipped with transducers and a data acquisition system for data collection.
