ACCELEROMETER LOCATION TECHNIQUE IN TERMS OF VIBROACOUSTIC DIAGNOSTICS OF STEERING AXLE FOR WHEELED TRACTORS
Keywords:
accelerometer, vibroacoustic diagnostics, driven bridge, tractor, amplitude of oscillations, recorded signal, errorAbstract
Tractors experience vibration and road shocks while moving the rasping surface of the road. The main units that protect the tractor from the dynamic effect of the road that reduce vibrations are steering axle and tires. Tractor steering axle in roadworthy condition provides optimal car control, traffic safety, service life and performance reliability. Faulty components of tractor steering axle make car control and tractor durability worse, impair the safety and degrade ergonomic characteristics. Faulty steering axle causes vibration of the tractor frame. As a result, riveted and threaded joints are released, the alignment of the engine and gearbox is set out, and additional load in main parts arises. Vibration of the tractor accelerates wear and causes detail failure. Therefore, mechanical validation of steering axle is an up-to-date issue in operation and maintenance. The primary concern of this study is to examine the influence of vibroacoustic transmitter location on vibration recording reliability of tractor steering axle. New technique for determining the location of the accelerometer in terms of vibroacoustic diagnostics of tractor steering axle is suggested by the authorReferences
