- Summary:
- This paper discusses the design and analysis of the Three-point linkage of an agricultural tractor for uncommon abusive usage practices during haulage applications. Some operators use the Three-point linkage for generating additional traction to navigate gradient surfaces, which requires additional wheel torque to overcome road slope when the trailer is attached. These maneuvers induce higher loads on Three-point linkage components, such as the lower link, lift rod, and powertrain components, which may lead to structural failures.A virtual simulation and lab-level test methodology need to be established to simulate the usage pattern upfront and predict potential failures. Multi-body dynamics (MBD) simulation was deployed to simulate the physics and extract realistic loads for Computer Aided Engineering (CAE) analysis. Data acquisition was carried out to record the strain levels during the uncommon haulage usage practices, which will be used for further studies. CAE analysis has been carried out to identify the exact hotspot locations. A correlation established between CAE and physical tests showed above 90% correlation. Further iteration has been carried out to meet durability CAE criteria and the final design successfully passed all physical validation and was implemented in the tractor model. The design validation method is now established to help in validating three-point linkage components for uncommon abusive practices also, thus avoiding surprise failures
