Human Body Vibrations

Whole-body and hand-transmitted vibrations are caused by vibrations transmitted through the seat or the feet or through the palms and fingers by workplace machines, tools and vehicles. FlexPro’s Human Body Vibrations option lets you analyze the effects of such vibrations on the human body. The analysis wizard provides you with a complete analysis based on the measured acceleration signals and includes daily exposure, the times until the exposure action value and the exposure limit value are reached, and specifies whether measures should be implemented or immediate action should be taken.

Features
Analyze whole-body and hand-transmitted vibrations:

• Evaluate single and triple axis acceleration signals
• Pre-defined weighting filters and k-factors for health assessment, comfort/buildings and railway vehicles
• Custom weighting filters and k-factors
• Calculation of 12 parameters, including aw, peak value, crest factor, MTVV VDV, eVDV, VDVexp, A(8), duration of exposure action value and exposure limit value
