Vibration Diagnostics in the Assessment of the Vehicles Bodywork Technical State Procedure

An integral part of every vehicle, the car body plays an important role in aspects such as safety, aerodynamics, aesthetics and comfort.Studies of the dynamic properties of mechanical structures using modal analysis methods are now very widespread.The essence of this analysis is to obtain information about the object in the form of the so-called modal model, which consists of modes of natural vibrations, natural frequencies and damping coefficients, mass and dynamic stiffness.The paper presents the possibilities of implementing vibration diagnostics in the assessment of the vehicle structure technical state with modal analysis.
