ABSTRACT: During the tractor movement, with being attached to the hitch-system working equipment over Rough road surfaces oscillation of the machine take place. These oscillations are a reason of pressure pulsations in the hydraulic hitch-system. The pressure pulse reduction in the tractor Hitch-system is important for increasing of the system components lifetime. Pressure oscillation damping in the tractor hydraulic hitch-system can reduce overall system oscillations and improve the driving control. The design of spring in suspension system is very important. In this project a shock absorber is designed and a 3D model is created using Solid works. The model can be changed by changing the thickness of the spring. Structural analysis and modal analysis are done on the suspension system by varying material for spring, Spring Steel and Beryllium Copper. The analysis is done by considering loads, tractor weight, single person and 2 persons. Structural analysis is for validating the strength and modal analysis is for determining the displacements for different frequencies for number of modes. Comparison is done for two materials to verify the best material for the spring in suspension system. Analysis done in ANSYS.
