Abstract
A method for analysing tire vibration characteristics and an apparatus for carrying out the method, wherein the apparatus includes a stiff frame including a wheel support for supporting a wheel with a tire to be analysed. A base part is flexibly connected with the frame by elastic means. The elastic means is embodied such that the frame is flexibly supported in one predefined functional direction. An actuator is provided for exciting vibrations into the wheel. The method and apparatus allow separate analysis of the natural vibrations in all four functional directions.

19. A method for non-destructive analysis of natural vibrations of a tire comprising the steps:
-
fitting a tire to be analysed on a wheel; arranging said wheel in an apparatus comprising a wheel support supporting said wheel flexibly in a predefined functional direction; excitation of vibrations in said wheel by means of an actuator; measuring an input signal at a contact surface between said tire and said wheel; measuring an output signal at a surface of said tire; and calculating transfer function of said tire by means of the input signal and the output signal. - View Dependent Claims (20, 21, 22)
