Diagnostics of the On-Vehicle Shock Absorber Testing

The practical problems that usually come up during the on-vehicle testing of motor car shock absorbers have been discussed. Results example tests carried out to EUSAMA standard procedure were compared test results obtained with using newer methods, i.e. phase angle method and half power bandwidth (HPBM). issue incompatibility typical excitation applied by diagnostic suspension testers one often occurs in road conditions has also raised. It shown wear may affect value braking deceleration cars ABS (anti-lock system) when moving on uneven ground.The main objective work was assess usefulness reliability various methods intended for absorbers.
