Natural frequency and modal analysis of tractor vibration system.

ABSTRACT: This study examines the natural frequency and frame vibration pattern of the tractor vibration system, with an agricultural wheeled tractor serving as the research object. Theoretical natural frequencies of vertical and pitching vibrations for a planar vibration model of a tractor with two-degree-of-freedom biaxial rigid suspension were derived, and experiments were conducted to test the vibration characteristics and natural frequency of a tractor traveling at moderate speeds on a Class D road surface. Modal analysis of the structure of the tractor frame was then carried out using ANSYS Workbench software. The findings indicate that the vertical and pitching vibrations of the fuselage are interrelated, with the natural frequency being contingent upon the mass of the tractor, the rotational
