Design and Development of Drop Centre Axle for 2WD Tractor
Longitudinal instability is the major factor to lead tractor accident. To prevent the accident, stability has to maintain that depends on tractor CG height. The CG can be maintained during operation by raising or lowering the front portion of the tractor. For lowering the front portion of tractor from normal position, a drop centre axle was used. This axle was designed in CATIA and finite element analysis was carried out in ANSYS. After analysis, trapezoidal frame with 10° side angle of 8 mm plate thickness was selected for its development. The maximum induced stress was 395 MPa, and its total deformation was 1.09720 mm. The axle weight was found to be 39 kg. The axle was developed and installed in the tractor that will help in lowering the front portion of tractor to 300 mm. It enhances the stability and accordingly maximum pulling capacity during operation.
