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...

Aiming at the problem that friction heating phenomenon of rigid piston in traditional shock absorber has not been well treated, based on idea variable volume, a is invented, and its structure throttling characteristics are studied. On this basis, designed for vehicle. In absorber, flow resistance structures paths oil flowing through different under various working conditions. According to equiv...
