ABSTRACT:
A method and apparatus for testing shock absorbers installed on vehicles whereby one tire of the vehicle is placed on a supporting plate of a test stand which is oscillated. The velocity of the plate during oscillation and the dynamic tire pressure on the supporting plate are detected and corresponding signals produced. The signals are divided, one by the other, after being peak rectified to produce a quotient which represents tire quality signal. Resonance is detected by differentiation of the velocity signal and the tire quality signal transmitted to an indicator only during resonance.
