The methodology of determining the place of installation of accelerometers during vibrodiagnostic of controlled axes of wheeled tractors

Abstract

When driving on a road with an uneven surface, the tractor receives shocks and oscillates. The main components that protect the tractor the dynamic action of the road and reduce fluctuarions and vibrations to an acceptable level are the steered axle and tires. A serviceable steered axle of a wheeled tractor provides optimal controllability, traffic safety, durability and reliability of work. The work with faulty components of the steered axle impairs the controllability and stability of the tractor, reduces the safety of its movement, impairs ergonomic indications. A faulty steered axle contributes to the vibration of the tractor frame, as a result of which riveted and threaded connections are weakened, the alignment of the engine and gearbox is disturbed, and additional loads occur in the body parts. Vibration of the whole tractor accelerates wear and causes breakage of many parts. Therefore, monitoring the technical condition of the steered axle of a wheeled tractor is an actual task in the field of exploitation and repair of equipments. The article presents a method for determining the location of accelerometers for vibration diagnostics of steered axles of wheeled tractors.
