What are the effects of slip angle?
The ratios between the slip angles of the front and rear axles (a function of the slip angles of the front and rear tires respectively) will determine the vehicle's behavior in a given turn. If the ratio of front to rear slip angles is greater than 1:1, the vehicle will tend to understeer, while a ratio of less than 1:1 will produce oversteer. Actual instantaneous slip angles depend on many factors, including the condition of the road surface, but a vehicle's suspension can be designed to promote specific dynamic characteristics. A principal means of adjusting developed slip angles is to alter the relative roll couple (the rate at which weight transfers from the inside to the outside wheel in a turn) front to rear by varying the relative amount of front and rear lateral load transfer. This can be achieved by modifying the height of the roll centers, or by adjusting roll stiffness, either through suspension changes or the addition of an anti-roll bar.
How to Calculate Slip Ratio Defined According to SAE J670?
Slip Ratio Defined According to SAE J670 calculator uses Slip Ratio = Wheel Angular Velocity*Effective Rolling Radius for Free Rolling/(Axle Speed over Roadway*cos(Slip Angle))-1 to calculate the Slip Ratio, The Slip ratio defined according to SAE J670 formula uses the effective rolling radius for free rolling at zero slip angle to evaluate the slip ratio. Slip Ratio is denoted by SR symbol.
How to calculate Slip Ratio Defined According to SAE J670 using this online calculator? To use this online calculator for Slip Ratio Defined According to SAE J670, enter Wheel Angular Velocity (Ωw), Effective Rolling Radius for Free Rolling (Re), Axle Speed over Roadway (VRoadway) & Slip Angle (αslip) and hit the calculate button. Here is how the Slip Ratio Defined According to SAE J670 calculation can be explained with given input values -> 0.221955 = 44*0.82/(30*cos(0.087))-1.
