Title: Uniformity measure methode of Tire
Inventor: AHN SEUNG WAN
IPC: G01M17/02
Filed: 2002-07-22
Abstract: PURPOSE: A method for measuring uniformity of tires is provided to precisely measure uniformity of the tire by reducing error derived from a non-roundness of a rim, which supports the tire. CONSTITUTION: A waveform affected by a rim is obtained through a filtering work by using Fourier series. The waveform is a vibration deviation derived from a non-roundness of the rim. Thus, the waveform is converted into a mm unit so as to apply the waveform to a tire. Then, a spring constant is calculated according to a following equation. F = KX, wherein, F is force, K is a spring constant, and X is a distance. Thus, the vibration deviation is equal to a value obtained through multiplying the spring constant of the tire to be measured by the non-roundness of the rim. Since the vibration deviation and the spring constant are already known, the non-roundness of the rim is easily calculated.
