摘要:
This method is used to determine the strength of the handshake. In particular, it concerns the clamping force when determining human exposure to vibration transmitted during work by hand tools and the assessment of the degree of impact of vibration on the human body. The method uses a known EMG test, in which the hand grip force is measured simultaneously during the calibration phase, using a known hand grip measure, and an electromyographic measurement of the same hand is performed. It is characterised by the fact that during the calibration phase, the measurement signals are transmitted through appropriate processors to the microprocessor system,where a linear or non-linear transition function is selected between the hand EMG signals and the hand grip force. In the appropriate measurement phase, the force of the hand grip on any object shall be measured on the basis of the specified parameters of the transition function and on the current EMG signals received and processed. The measurement conditions shall be identical to the calibration conditions. During the measurement of the EMG, at least one pair of measuring electrodes, the first (J) and the second (K) shall be applied to the forearm in the area of muscle activity and in a passive, weak-muscled place,one reference electrode (L) shall be attached. The difference between the measurement electrode signals is amplified and the resulting differential signal is transmitted to the analogue (AC) converter,and the reference electrode (L) signal is the reference point for that converter (AC),the result signal is recorded in a microprocessor.Sposób służy do wyznaczania siły zacisku dłoni. W szczególności dotyczy siły zacisku podczas określania ekspozycji człowieka na drgania przenoszone podczas pracy narzędziami ręcznymi i oceny stopnia wpływu drgań na organizm człowieka. Sposób wykorzystuje znane badanie EMG, w którym w fazie kalibracji równocześnie mierzy się siłę zacisku dłoni, za pomocą znanego miernika siły, zacis
