Human & Whole Body Vibration Testing

The human and whole-body vibration module tests are used to measure the effect of vibration on the human body. The extracted parameters allow the simple assessment of the injured risk for workers, exposed to constant vibration. Dewesoft solution supports the whole-body and hand-arm vibration measurement are supported according to all relevant international standards - ISO 5349, ISO 8041, ISO 2631-1 and ISO 2631-5.
Picture

Whole Body Vibration Measurement

Human exposure to whole-body vibrations should be evaluated using the method defined in ISO 2631-1:1997. Whole-body vibration is applicable to motions transmitted from workplace machines and vehicles to the human body through a supporting surface. For health and safety evaluations, this is through the buttocks and feet of a seated person or the feet of a standing person.
Picture

Hand-Arm Measurement

Hand-arm vibration is experienced through the hand and arm. Daily exposure to hand-arm vibration over a number of years can cause permanent physical damage, usually resulting in what is commonly known as "white finger syndrome", or it can damage the joints and muscles of the wrist and / or elbow.

Measurement of hand-arm vibration refers to three main cases:
​
When the operator's hands have direct contact with the surface of the vibrating machine (steering wheel or handle)
When the operator feeds the machine with the ​material through which the vibration is transmitted to a hand (wood cutting)
When the operator holds the vibrating device in hands (drills, pneumatic hammers)
Picture

Calculated Vibration Parameters

Parameters can be calculated either as overall values, which means that we have only one value at the end of the measurement and / or interval logged values. If we have an interval logged values, the time interval for logging is defined in seconds.

RMS - A statistical measure of the magnitude of a weighted signal
Peak - Maximum deviation of the signal from the zero line
Crest - The ratio between the peak and RMS
VDV - Fourth power vibration dose value
MSDV - Motion sickness dose value
MTVV - Maximum transient vibration value, calculated at a one-second interval
Picture

 Measurement of SEAT - Seat Effective Amplitude Transmissibility

The determination of SEAT does not directly give information about human exposure to vibration. The goal of the measurement is to determine the capability of a seat design to attenuate the vibrations present in a vehicle - to protect the driver from excessive vibrations.

The measurement, therefore involves a determination of the vibration magnitude at two positions (SEAT is computed as the ratio between these two magnitudes):
​
On the seat pan
Directly on the floor of the vehicle right underneath the seat
Picture

Lumbar Spine Measurement

The adverse health effects of prolonged exposure to the vibration that includes multiple shocks are related to dose measures.

The calculation of the lumbar spine response described in ISO 2631 assumes that the person subjected to the vibration is seated in an upright position and does not voluntarily rise from the seat during the exposure. Different postures can result in different responses in the spine.

The determination of the spinal response acceleration dose involves the following steps:
Calculation of the human response
Counting of number and magnitudes of peaks
Calculation of an acceleration dose by application of a dose model related to the Palmgren-miner fatigue theory
