The PTO shaft is a crucial component in agricultural machinery, responsible for transferring power from tractors to attached implements. Ensuring its reliability and performance is vital to prevent mechanical failures that can lead to downtime and increased maintenance costs. This study presents a comprehensive dynamic analysis of a PTO shaft using FEM software ANSYS (Student's version). The analysis begins with the creation of a detailed finite element model of the PTO shaft, incorporating material properties, geometric dimensions, and boundary conditions reflective of real-world operating scenarios. The results of simulations are first verified using an experimental result. The structural analysis is then carried out and the results are further verified through the relevant data in literature. The work is then extended to simulate the dynamic behavior of PTO shaft. Modal analysis is conducted to identify findings provide valuable insights into the design and optimization of PTO shafts, thereby suggesting modifications to enhance their durability and operational efficiency. The results have been reported to include three types of alloy material: a) SAE 4140 used in literature to verify the results, b) P100/6160 Al and c) Boron Al, latter are alloys of aluminum, hence provide good strength to weight ratio maintain desired stiffness. The structural and modal analysis of PTO shafts have been carried for all the three types of materials and comparative study has been presented. From the structural analysis, it is observed that the stresses in all the materials are almost same however the new materials have been stiffer as compared to the traditional one. Using the new materials, the corresponding weight is significantly reduced. The natural frequency of Boron Al is significantly higher than the other two materials. Boron Al performs well in terms of natural frequency stability but shows the highest deformations at lower frequencies, suggesting it may be less suitable for applications with high dynamic loading at those frequencies. SAE 4140, on the other hand, provides the highest stiffness and lowest deformation at lower natural frequencies, making it the best choice for environments where resistance to resonant vibrations is critical. Thus, by leveraging ANSYS for dynamic analysis, this research contributes to the development of more robust agricultural machinery, thereby improving reliability and reducing maintenance costs.
