    Abstract: In one aspect, a vibration damper includes first and second diaphragm flexures defining a cavity therebetween, a damping material disposed in the cavity, and a mass connecting the first and second diaphragm flexures. In another aspect, an assembly includes a load cell body having two opposed sides, a first vibration damper operably connected to the load cell body at the first side and a second vibration damper operably connected to the load cell body. In yet other aspects, a machine are method are used to test a tire and wheel assembly, wherein the machine includes a road surface simulator, a spindle hub, a spindle housing, a frame, a spindle support, and a damper assembly. The damper assembly is joined to the spindle housing or to the spindle support and is configured to attenuate forces or motions of the spindle hub or the spindle support.

    Abstract: A system and method for use with a testing machine having an actuator for applying loads or displacements to a test specimen, the system and method comprising a sensor operably coupled to the test specimen to sense motion or force and provide a sensor output signal. A signal transformation processing circuit coupled to receive the sensor output signal and configured to provide an output signal related to an audible and/or inaudible acoustic domain for test specimen and virtual components coupled to the test specimen. An output device coupled to receive the output signal related to the audible and/or inaudible acoustic domain and render information related to vibrations made by the test specimen and the virtual components coupled to the test specimen.

    Abstract: A specimen support assembly for testing an elastomeric test specimen comprises first and second specimen supports. A force transducer and accelerometer assembly is connected to a second end of the first specimen support opposite the elastomeric test specimen and includes a force transducer and a first accelerometer operably coupled in series with the force transducer, the first accelerometer configured to measure acceleration of a first end of the test specimen when mounted in the first specimen support and provide a first acceleration output signal. An elongated strut has a first end connected to the force transducer and accelerometer assembly on an end opposite the first specimen support and has a second end opposite the first end. A second accelerometer is configured to measure acceleration of a second end of the test specimen when mounted in the second specimen support and provide a second acceleration output signal.
