| Abstract: | In this paper, a novel dynamic and quantitative method for measuring tread flats is described. To solve the vibration problem of the existing measurement mechanism, the mechanical dynamic model is established. The vibration frequency and critical-damping is calculated and dynamic response is simulated, which can provide theoretical reference for further perfecting the design of the measurement mechanism. |
