In which, [R.sub.l] and [R.sub.r] are the rolling radius of the left and right wheel, respectively; [[lambda].sub.g] is the wheel tread equivalent conicity.
where, [V.sub.x] is the longitudinal velocity of the vehicle, [R.sub.e] is the effective rolling radius and [[omega].sub.w] is the angular velocity of the wheel.
The rolling radius of the wheel at both sides is different; therefore, the rolling distances of the wheel at both sides are different at the same time and the wheel set moves under the action of lateral creep force.
E means the density of the material elastic modulus, p means rolling radius. [gamma] means the larger the elastic modulus, the greater the material density and the radius, the greater the inherent frequency of the rolling element.
The variable [V.sub.0] in (11) is the reference velocity that can be simply calculated as the product of the roller velocity [[omega].sub.r] and the roller rolling radius [r.sub.r], as shown in
The module's optional features let users control how tire slip and rolling radius are calculated and include tire transients through differential equations.
* A series of wheel-speed sensors including both magnetic-generating and semiconductor types by Sumitomo Electric and a tire-deflation warning system that detects 20 percent deflation levels under normal drix4ng conditions; the system measures tire rolling radius to determine deflation levels.
The XLD 70 has a smaller rolling radius (rolling radius = rolling circumference/2[Pi]) than the series 80 tyre with the same loading capacity.
The tire radius which relates the torque and circumferential force is rolling radius in the driven mode [r.sup.0'(").sub.wi].
where r is the rolling radius of wheel, n denote the recovery coefficient of tire, R represent [R.sub.Ai] or [R.sub.Bi].
This way the local rolling radius in each point on the wheel profile is R(t) = [R.sub.0] - z(t).
