The damping of the shock absorber is checked from the force response of the running gear to the oscillations of the vibratory platform and the relative phase function between the force exerted by the vibratory platform and the motion of the vibratory platform.

Why it's free to use
- Filed December 8, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 8, 2018.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
