VM-Body - Applications
VM-BODY is applied for measuring human whole-body vibrations. Whole-body vibrations are caused by vibrations or shocks which are transmitted by machines and vehicles in the workplace via seat or feet. If a person is exposed to strong whole-body vibrations, safety and health are endangered and it is proven that backache can be provoked or aggravated.
The "vibration directive” (directive 2002/44/EC) defines minimum requirements for the protection against risks arising from whole-body vibrations.
The measurement modes are based on the international standard ISO 2631. This standard not only covers whole-body vibrations from a medical view, but also comfort assessments, e.g. for passengers in rail vehicles (trains, underground railway, etc.). Thus, the comfort of a person during the transport can be assessed objectively and according to an internationally accepted method.
As an extra measurement mode, the identification of transmission characteristics of seats (SEAT value
) is available in VM-BODY+. For each measurement, the Pro version additionally offers an analysis
in frequency domain - for both, the unweighted signal and also with weighting filters. This way, causes (e.g. structural ones) which contribute to the total vibration value most are detected quickly.
Comfort and health assessment
VM-SHIP is used to measure human whole-body vibrations on ships. Whole-body vibrations are caused by vibrations which are transmitted from drives and machines to a person that is standing, sitting or lying down. If the crew is exposed to strong whole-body vibrations, safety and health are endangered. Too strong vibrations also diminish the comfort of the passengers in their cabins.
The international standard ISO 6954 provides guide values for different classes of rooms. Exceeding these guide values may cause complaints. For acceptance inspections, parties can use these guide values or agree on their own values.
VM-SHIP+ additionally offers a frequency analysis
of the weighted and unweighted vibration signal. This can help to find the source of vibration.
