Model Motion System (MMS)

To achieve ultimate dynamic realism with rolling road systems, MTS has developed an advanced Model Motion System (MMS) capable of applying force and motion in multiple degrees-of-freedom to the vehicle models during aerodynamic simulations.

Overhead hexapod motion platform positions test model (pitch, roll, heave and internal yaw drive) in the flow stream above the rolling road
Model-based 6DOF balance measures forces and moments
Enables continuous motion playout with high precision and accuracy
Fully synchronized with through-the-belt force measurement and optional wheel support arm systems
Typically used with 50% and 60% scale models

The longitudinal restraint portion of the 3-Link Restraint is adjustable with either soft and rigid mounting. The soft mounting allows limited body motion during accelerations and decelerations to allow the driver to sense tuning results of the vehicle control unit. Range of motion of the longitudinal restraint is limited by the air bearing range in the tire input assemblies.

The max weight of vehicles tested on the K&C is customer suspension dependent.During K&C vertical and roll kinematic tests the suspension must be pushed into into the jounce bumper, which usually takes 1.5-3x the corner weight of the vehicle.For example, if the vehicle is 4 mtons = 1 mton per corner weight, it would take approximately 1.5 to 3 mtons per corner to push the suspension up to the jounce bumper. Thus, the PC K&C can be used for 4-5 mton vehicles and the LT K&C used for 8-10 mton vehicles.
