There are a number of devices which can be used to measure slip angle on a vehicle as it moves; some use optical methods, some use inertial methods, some GPS and some both GPS and inertial. Various test machines have been developed to measure slip angle in a controlled environment. A motorcycle tire test machine is located at the University of ...
Large positive values of scrub radius, 4 inches/100 mm or so, were used in cars for many years. The advantage of this is that the tire rolls as the wheel is steered, which reduces the effort when parking, provided you're not on the brake. The advantage of a small scrub radius is that the steering becomes less sensitive to braking inputs.
Front suspension of a race car — the caster angle is formed by the line between upper and lower ball joint An example of a chopper with a raked fork at an extreme caster angle The caster angle [ 1 ] or castor angle [ 2 ] is the angular displacement of the steering axis from the vertical axis of a steered wheel in a car , motorcycle ...
Opel car factory new car testing on chassis dynamometer Saab 96 on mobile dynamometer. Tractive force control/Force constant - in this mode the dynamometer holds set force regardless of speed or other parameters. The specified Force can be distributed evenly between the axles or in different amounts between different axles in the case of ...
Instead of the radial distance r geographers commonly use altitude above or below some local reference surface (vertical datum), which, for example, may be the mean sea level. When needed, the radial distance can be computed from the altitude by adding the radius of Earth, which is approximately 6,360 ± 11 km (3,952 ± 7 miles).
It is the primary measure of how drivers sense a car's turning visually. Axes of a ship and rotations around them. It is important in electronic stabilized vehicles. The yaw rate is directly related to the lateral acceleration of the vehicle turning at constant speed around a constant radius, by the relationship
Package with one tilt indicator. A tilt detector or tilt indicator is a device which indicates whether a tilt has occurred. Tilt detectors can be used on shipments of tilt sensible items to indicate whether a potentially damaging tilt have occurred.
Figure 1 Hard wheel rolling on and deforming a soft surface, resulting in the reaction force R from the surface having a component that opposes the motion. (W is some vertical load on the axle, F is some towing force applied to the axle, r is the wheel radius, and both friction with the ground and friction at the axle are assumed to be negligible and so are not shown.
