Windrawwin Today Test – Tips To Ensure Your Vehicle Stability
The Windrawwin Today Test is a way to assess wind, hail and glare levels. It is best performed in mid-morning or late afternoon when the sun is at its maximum angle of incidence. It can be done on a rough road or paved surface, but not on gravel or grass surfaces as it is unable to track on those surfaces. It is also an ineffective testing method if it is done in unfavorable weather conditions such as rain, sleet or snow.
The Windrawwin Today Test is a simple test which involves facing a 15 degree angle to the wind and rotating the steering wheel to obtain a front-to-rear rotation. The chart then records the angle of the horizontal component in degrees between the steering wheel and the windshield glass. This graph is known as the wind velocity profile. Once the wind velocity reaches the lowest level possible, it is recorded as one-level horizontal velocity. The next line is the tilt angle and represents the amount of wind force which actually affected the steering wheel.
The dynamic formula for determining how much pressure was applied to the steering wheel is given by: V = C Dv. D is the degree of tilt angle, v is the measured wind velocity, C is the pressure from the steering wheel and I is the tilt angle. If the steering wheel is shifted by 45 degrees, so the formula states that the new steering angle must be equal to the one calculated at the beginning of the test.

If the horizontal component of the velocity is lower than the vertical component, the force exerted on the steering wheel must be less than that on the wheel, and this means the steering angle has increased. This is also referred to as wind whip, which will result in the steering wheel being affected by the tilt angle.
If the dynamic formula is followed, it will indicate that the steering angle will be increasing with the height of the steering wheel. If this is the case, it will show that the condition of the steering wheel may cause vehicle stability problems.
A constant tilt angle of the steering wheel will result in a constant wind whip, which will have the same force on the vehicle stability, and will not alter in any measurable manner. Such a condition is known as perfect balance.
A double degree wind whip is recorded if the vehicle is at a higher point on the windshield’s contact surface than it is actually located. This will lead to the car rolling forward or backward during the test. On a light, smooth road, no roll over is likely to occur as this would not be unusual.
There are some instances in which vehicle stability is beyond the capability of the wind rake, especially when the steering angle is very low. These conditions are likely to occur on roads with areas of rocks, grit, sand or potholes.
If the vehicle stability cannot be restored during the test, the vehicle is considered not reliable. It must be avoided in situations where it is necessary to use extreme caution.

When the stability of the vehicle is affected by adverse weather conditions or weather related factors, the vehicle should be excluded from this test. This will reduce the potential effect of any weather-related factors on the vehicle. The same is true if the vehicle is involved in a collision.
It is advisable to not perform the Windrawwin Today Test on roads with normal weather conditions, as the wind may be higher in places than on normal roads. To avoid this problem, it is better to park your vehicle on a street with a small concentration of houses and buildings in the vicinity. The wind may blow the test instrument’s coverage area.
It is essential to perform the Windrawwin Today Test only after taking the vehicle stability into consideration. In addition, even if the vehicle does not roll, the stability of the steering should be checked, and all other safety devices fitted.
