Radial Force Variation. The variation friction coefficient radial force, μ = μ(Ri). Download The wheel is rotated at a low speed and measures the variation (pounds. As the tire rotates, the spring elements of the tire make contact with the road surface and are compressed..

The radial force variation can be expressed as a peak-to-peak value, which is the maximum minus minimum value, or any harmonic value as described below Radial force variation or road force variation [1] (RFV) is a property of a tire that affects steering, traction, braking and load support

The variation friction coefficient radial force, μ = μ(Ri). Download

A variation between 3,900 and 4,100 N (880 and 920 lbf) would be characterized as an 200 N (40 lbf) radial force variation (RFV) the remaining force metric, and the sum of the tire force metric and the wheel force metric which are derived from the method of controlling the radial force variation of the tire/wheel assembly described herein, are useful analytics that may be examined via statistical analysis or individual component diagnostics to quantify factors affecting the radial force variation of the tire/wheel assembly. Moreover, this leads to undesirable vibrations that hinder the performance of equipment such as automobile tires

Radial force variation with stiffness nonuniformity in two belt plies. Lateral force variation will also fluctuate in force even if driven in the most consistent manner. Force variation for a DC01 steel sheet of thickness 1.15 mm with wall angle 60°, tool diameter 25 mm, depth increment 1.06 mm plotted against 'g', the length of the generating line of the cone; F z is the axial force, F r the radial force and F t the tangential force [51] [with permission from publisher].

Average variation of radial force between two consecutive cutting edges. It may be of benefit to have the lowest RFV assembly to the front left corner . Some tire manufactures mark the sidewall with a red dot to.
