To correctly quantify tire noise, which is a necessary data point for all new tires in accordance with the new EC Tire Labeling act, tire manufacturers are turning to specialized “noise testing” laboratory machines.While these machines do not test on their own, they provide a means of driving and/or loading wheels for easier data acquisition.
The Poling Group Noise Tester is designed to be used as a wheel drive mechanism for analyzing the sounds produced by tires in contact with a road surface.
The machine is equipped with a load table located between two drums, on which a load cell-mounted running hub or vehicle axle can be attached for off-vehicle tire testing.
The load table and dual-drum drive, located below floor level, drive one or two wheels of a vehicle supported by the drums. The drums are connected by a pneumatic clutch to enable one or two drum operation.
