Opis:
There is a lot of controversy when we consider the most popular method of measuring local vibrations to estimate danger on hand tools operators. This is because of commonly used adapter that represents many faults, from which the most significant are: strong impact of grip and placing adapter between a hand and a tool handle. What we propose in this article is a measurement system including a band placed on a wrist. This solution highly eliminates defects mentioned above, but seems to be too trivial to maintain high quality of measuring process. The purpose of this article is to estimate the quality of this new solution in respect of some basic categories in which measurement errors occur.

Opis:
One of the most important factors in hand-arm system research is the information about hand grip force and pressing force on a tool handle. This article focuses on an alternative method to measure grip force. For grip force, one of the most popular solutions is a special handle with force sensors. However, when we want to use it with regular hand tool like e.g. a drill, it seems to be uncomfortable because we must interfere in handle construction. A solution proposed in this article is based on technique for evaluating and recording the electrical activity produced by muscles, electromyography (EMG). It has been assumed that EMG signal will be proportional to muscle tension responsible for palm grip. This solution have one significant advantage when comparing to special handle. It can be used with regular tool without interfering in the handle. Measurement presented in this article have been carried out with use of surface electromyography (sEMG). It is not invasive method which enables to measure EMG signal through placing stickers with electrodes directly on a skin.

Opis:
Recently we have used better solution to protect hand tool operators. In spite of our good intentions there is still endanger on high level vibration. For that reason we need to improve protection constantly. One of the most important properties of hand-arm system is knowledge about spectral response. In this article we try to obtain spectral response in narrow band-pass filters in accordance with IEC 1260:1995 and ANSI S1.11-2004 standards (implemented in LabVIEW software). To measure signals we used accelerometer placed on a wrist and on a tool. Of course the vibrations are attenuated by hand (cartilage, muscular tissue) but the question was what the shape of envelope in measurement range is. Our research used measurement on two different systems. The one was based on vibration inductor (laboratory environment), the second one used drill (real environment). This research is a part of a wider project to make virtual model of hand-arm system.
