Split Transmission of Tractor with Automatic Gearbox

Quantification of condition indicator performance on a split torque gearbox

The requirement for higher energy density transmissions (lower weight) in helicopters has lead to the development of the Split Torque Gearbox (STG) to replace the traditionally planetary gearbox by the drive drain designer. This may pose a challenge for the current gear analysis methods used in Health and Monitoring Systems (HUMS). Gear analysis uses time synchronous averages to separates in fr...

Multi-objective Optimization of Hybrid Electric Vehicle Equipped with Power-split Continuously Variable Transmission

This paper aims to find the efficient state of hybrid electric vehicle (HEV) by simultaneous optimization of the control strategy and the power train. The power transmission employed in this vehicle is a power-split continuously variable transmission (CVT) which uses several fixed ratio mechanisms. After describing this transmission, the rules of electric assist control strategy are introduced....

Faults detection of gearbox of MF285 tractor based on Wavelet Packet Transform and ANFIS

In this paper, an approach based on Wavelet packet transport, principal component analysis is presented for detection of fault diagnosis of gearbox of MF285 tractor. The vibration signal acquired from the experimental set up has been used to diagnose the condition. An acceleration sensor is used to pick up the vibrational signals by experimental set up. After acquisition vibrations data, proces...

Characterization of Vibration Transmission Paths for Gearbox Condition Monitoring

For gearbox condition monitoring, the position of the accelerometers can be crucial for the detection of possible defects. However, little information can be found in the literature for engineers in setting up condition monitoring. This study is to investigate the characteristics of gear vibration and its transmission path for sensor placement and reliable fault diagnosis. Vibration sources pro...
