摘要： A system (10) for measuring the dynamic orientation of the plane of a wheel (12) on a vehicle (14). The system (10) includes a test surface (16) which rotates with the wheel (12) and a orientation-determining device (18) which is unattached to the vehicle (14). The test surface (16) is positioned in a plane corresponding to the plane of the wheel (12) and the orientation-determining device (18) determines the orientation of the plane of the test surface (12) at a specific point of time while the vehicle is being driven. A processor (20) receives output signals from the orientation-determining device (18) and converts the output signals into data corresponding to the orientation of the wheel plane for the specific instant in time.

摘要： A friction testing machine (20, 120, 320, 520, 620) and method for measuring friction characteristics between a test sample (S) and a friction surface (44, 144, 544, 644). The machine and method are particularly suited for measuring the coefficient of friction between a rubber specimen or a treated element and different friction surfaces at different sliding velocities, contact pressures and orientations. The machine includes a carriage (58, 158, 358, 558, 658), a motion device (76, 176, 376, 576, 676), a sample holder (62, 162, 362, 562, 662), a variable weight loading device (68, 168, 368, 568, 668), and a force measurement device (92, 192, 392, 592, 692). A processor (28, 128, 528, 628) controls the motion device, controls the variable weight loading device and/or records the measurements obtained by the force measurement device.
