Flat Belt Tire Test Machine

The A&D Flat Belt Tire Test Machine is an indoor tire force and moment testing machine. It allows the tire to be tested against a flat surface under dynamic conditions. The flat surface is emulated by an electrically controlled belt-pulley assembly while the tire load is supported by an air bearing (for passenger cars loads) or a water bearing (for higher loads) that is present under the belt. This belt-pulley assembly rests over a hydraulic shaker system that can emulate tire vertical motion and slip-angle generation in a highly dynamic fashion. The tire stand itself is capable of changing the tire vertical load and camber angle during the test run. Forces and moments experienced by the tire are measured at a high sample rate using A&D’s 6-component Plate Force Sensor (PFS) mounted on the tire stand. The configuration, range and performance can be customized depending upon the intended application.
