Wavelet transfer function in the analysis of the influence of a palm grip on actual vibrations of an upper limb.
نویسندگان
چکیده
Algorithms used to determine the vibrations to which hand-tool operators are exposed take into account only vibrations measured on a tool. Thus, the significant influence of constraints joining the elements of the tool-operator system is neglected. This paper attempts to determine the influence of grip on vibrations recorded both on the tool and on the limb. The estimation was based on the use of the wavelet transfer function, in which the analysis was done by filtration with wavelet functions. Signals recorded with the specially designed system were utilised in investigations.
