The Influence of the Chassis’ Parameters on the Truck Vibrations Transmissibility

Abstract:

Abstract. A modal analysis of truck system was performed. Eigen frequencies and eigenmodes are described. In order to validate the model, the engine was tested with various excitations. Acceleration responses were measured and frequency spectral analyses were performed. The transmissibility was calculated as a ratio of the effective accelerations measured at M, R, Cs, Cd points on the truck structure. The eigenfrequencies of the truck structure are sensitive to the numerical parameters of the model. The influence of the thickness of chassis frame and of the geometry’s cross member on the vibrational behavior of the chassis and on the vibration transmissibility from the engine to the cab truck were studied.
