This research presents an overview of the necessary theory and standards for the research of the biodynamic response of a human body and its' vibroisolation protection. In the first part, two different biodynamic measuring devices are developed. The first device is designed in the shape of a handle and separately and concurrently measures the palm and finger responses to vibration excitation. The device enables triaxial measurements and can also be used for antivibration gloves testing. The second device was developed for single finger and finger parts biodynamic measurements. Based on the measured results a finger dynamic model is developed and also validated. The analytical finger model is designed as a system of rigid bodies and the material properties of the model were identified from the experimental data. The developed model serves as a simulator of the finger response to excitation and with added vibroisolation elements helps in the development and testing of antivibration protection of the human hands. At the end of this work, the upgraded analytical finger model is used to research different vibroisolation materials and some antivibration protection proposals are listed.
