Abstract
The dynamic characteristics of five types of widely used transducer adapters were compared in terms of vibration transmissibility between an accelerometer on the surface of the gripping area and another within each of the transducer adapters over a frequency range of 25–1250 Hz. Performance was also assessed from the ratio between two human vibration exposure levels, ahv, 1 and ahv, 2, measured using the two accelerometers over nine combinations of grip force and feed force. In this study, vibration transmissibility and ahv ratio of unity are considered. The vibration transmissibility and ahv ratio indicated that the flexible palm adapter provided the best estimate of vibration transmission to the hand. This transducer adapter exhibited the smallest deviation from unity for vibration transmissibility, which was <1.8 per cent over the frequency range, and ahv ratio, which was <4 per cent over nine combinations of grip and feed forces. From the investigation, the flexible palm adapter showed negligible distortion over the frequency range and high applicability, regardless of the gripping condition. The handle-type adapter provided the second-best estimate.
