Hand-arm vibration part II: Vibrational responses of the human hand

Thresholds for the perception of hand-transmitted vibration: Dependence on contact area and contact location

“…Decreased thresholds at frequencies less than 63 Hz with increasing contact area from the fingertip to the whole area of the hand seen in Experiment 2 may partly be influenced by increased transmission of vibration. A resonance of the hand-arm-system in the region of 30 Hz seems possible for the contact conditions employed Mishoe and Suggs;Sörensson and Burström, 1997). Vibration at 31.5 Hz may have been amplified by a resonance of the hand and arm when the whole area of the hand was in contact with a vibrating surface, resulting in a lowering of the thresholds at this frequency.…”

A Comparison of Biodynamic Models of the Human Hand–arm System for Applications to Hand-Held Power Tools

“…The three-and four-d.o.f. grip-force-dependent models proposed by Mishoe and Suggs [13], Reynolds and Falkenberg [14,15] and Gurram [33] would fall within this subgroup. Owing to the lack of adequate data on grip-force-dependent impedance characteristics and reported inconsistencies among the data derived under di!erent magnitudes of grip force [16], these models are analyzed for a constant magnitude of grip force.…”

“…models proposed by Miwa et al [30]; three-d.o.f. models proposed by Reynolds and Falkenberg [14,15], Meltzer [31], Mishoe and Suggs [13], Daikoku and Ishikawa [12], and Gurram et al [32]; and four-d.o.f. models developed by Reynolds and Falkenberg [14], and Gurram [33].…”

“…Mishoe and Suggs [13] investigated the in#uence of grip force on DPMI characteristics of the human hand and arm. The measurements were performed under vibration along the three axes in the 20}2000 Hz frequency range using three di!erent magnitudes of grip force: 13, 27 and 40 N. On the basis of measured data, three-d.o.f.…”

Independent responses of Pacinian and Non-Pacinian systems with hand-transmitted vibration detected from masked thresholds

“…The threshold contours are in good agreement with thresholds determined in previous studies with the same contact conditions and measurement methods (Morioka and Griffin, 1999;2000). contact conditions employed (Reynolds and Jokel, 1974;Mishoe and Suggs;Sörensson and Burström, 1997). Possibly, vibration at 31.5 Hz was amplified by a resonance of the hand and arm in the HAND contact condition, resulting in a lowering of all thresholds at this frequency.…”
