A full nonlinear finite element P205/70R14 passenger car radial-ply tire model was developed and run on a 1.7-meter-diameter spinning test drum model at a constant speed of 50 km/h in order to investigate the tire transient response characteristics, i.e. the tire three-dimensional free vibration modes transmissibility in X, Y and Z directions. The tire model was constructed in extreme detail with three-dimensional solid, layered membrane, and beam elements. The reaction forces of the tire axle in longitudinal (X axis), lateral (Y axis) and vertical (Z axis) directions were recorded when the tire rolled over a cleat on the test drum, and then the FFT algorithm was applied to examine the transient response information in the frequency domain. The result showed that this tire has clear peaks of 45, 40, and 84 Hz transmissibility in the longitudinal, lateral and vertical directions. This result was validated against previous studies by analytical, experimental, and FEA model approaches and showed excellent agreement. The parameters adopted in this FEA tire model were also compared with experimental work and the extraordinary agreement was also confirmed. The tire three-dimensional free vibration modes transmissibility was successfully detected virtually.
