Vibration Control System

Expanded functions can be performed using Road Force Measurement System VAS6230A in addition to the previously known balancers.
A special characteristic of this system is testing the radial force of wheel/tire during rolling.
For this purpose, a roller presses a force of approximately 635 kg against the wheel. This simulates the tire contact force against the street surface while driving.
Tire contact forces fluctuate due to radial- and lateral run-out and differing rigidity in the tires.
The Road Force Measurement System VAS6230A detects and stores the position of the maximum measured radial force in the tires. After that, the position of smallest dimension between rim flange and disc wheel center is measured.
