What is K&C Testing?

K&C testing is a special type of vehicle suspension testing.

The “K” stands for Kinematics – This is the suspension geometry (toe, camber, etc.). The “C” stands for Compliance – This is the suspension stiffness (i.e. how far do things bend when road loads come up through the tires).

For most people, measuring suspension K&C characteristics is very difficult – even in an extremely well-equipped shop. Imagine trying to put 2000 pounds of side load into a tire while measuring toe deflection! At Morse Measurements, K&C measurements are made easy thanks to our state-of-the-art Anthony Best Dynamics K&C test rig.

This test rig—the first of its kind to be independently operated and made publicly available in North America—grabs your vehicle chassis from the underside and can move it in vertical Bounce, Roll, and Pitch. The tires stay in contact with a level “road plane” at four individual wheel pads. These wheel pads can maintain zero scrub force (through continuous feedback force control) or they can introduce ground level forces to simulate braking, acceleration, and cornering loads at the tire contact patches. Precision digital encoders and load cells measure tire loads and wheel orientations at all times.

Remember, all these forces and displacements are applied slowly (quasi-statically) to capture suspension force-displacement relationships and friction. By measuring all these things at Morse Measurements – where everything is accessible and repeatable – you can reduce a lot of the guesswork (and costs!) associated with on-road/track test sessions.

K&C testing is not really “dynamic” testing at all – although it has a very close relationship to vehicle dynamics. K&C tests are quasi-static – all loads and displacements are applied quite slowly. This is done purposefully to look at force-displacement relationships and friction in the suspension. The AB Dynamics K&C test machine at Morse Measurements is specifically designed to displace and load a vehicle in our facility in ways that would be very difficult to do otherwise.
