Summary: | There are provided the tire motor for increasing or decreasing the tire rotational frequency Nt while the tire is being rotated around the tire rotational shaft , the rotational frequency measuring means for measuring the tire rotational frequency Nt, the drum motor for rotating the test drum around the drum rotational shaft at the constant drum speed Vd, the speed meter for measuring the drum speed Vd, the load applying means for pushing the tire against the test drum with the tire load Fz, the radial force load cell for measuring the tire load Fz, the tangential force load cell for measuring the tangential force Fx that is exerted on the tire , and the recording means for recording the measurement result of each of the drum speed Vd, the tire rotational frequency Nt, the tangential force Fx and the tire load Fz in association with every measurement time point during increasing or decreasing the tire rotational frequency. |
