Human Vibration Meter SV 106D

As defined by ISO 8041, a Human Vibration Meter (HVM) is a device that uses a vibrational transducer, signal processor, and display to measure human response to vibrations. HVM is typically used in hand-arm vibration measurements to prevent HAVS. In whole-body, they are typically used for the calculation of Vibration Dose Value.

What is a Human Vibration?

Human vibrations are mechanical vibrations that are transmitted directly to the human body, affecting different tissues in different ways. There are three types of human vibrations:

hand-arm vibration (ISO 5349);
whole-body vibration (ISO 2631);
low-frequency whole-body vibration in the frequency range from 0,1 Hz to 0,5 Hz (ISO 2631)

Human Vibration

Hand Arm Vibration Testing

Calculation of the daily exposure A(8)

The hand-arm vibration testing is based on the calculation of the daily exposure value normalized to an eight-hour reference period. This value is A(8), which is the square root of the sum of the squares (RMS) of the frequency-weighted acceleration values, determined on the orthogonal axes X, Y, Z defined in ISO 5349-1.

Vibration Dose Value

Calculating VDV for whole-body vibration

The vibration dose value VDV is calculated using the fourth power of the frequency-weighted instantaneous vibration acceleration. The whole-body vibration daily exposure A(8) is calculated at the highest (RMS) value or the highest vibration dose value (VDV).

Types of Accelerometers

MEMS vs IEPE Accelerometers Types

ISO 8041 mentions two types of accelerometers - IEPE and MEMS. Their construction and operation are very different. In IEPE accelerometers, piezoelectric materials are used, while semiconductor fabrication facilities are used in MEMS. As a result, MEMS accelerometers are more shock resistant and do not have a DC shift effect. They also consume less power and have a flat frequency response down to DC.

Human vibrational frequencies

How do you measure human vibrational frequency?

According to ISO 5349 and ISO 2631, human vibrational frequencies are measured using unweighted frequency spectra to identify the vibration sources. Once it is installed, the data logger stores the information about 1/3 octaves with configurable logging intervals.

How are vibrations measured?

The vibrations are measured by sensors that are attached to the meter with cables. The sensors are placed near the contact with the vibrating surface of industrial machinery. Take a look at some of the features that make the SV 106D the world's leading human vibration meter.

Vibration Measurement Methods

HAVS

Hand arm vibration syndrome

HAVS is a form of vascular disorder with low blood circulation in the fingers that manifests as an occupational disease as a result of hand-arm vibrations. Learn how to take measurements of hand-arm vibration to prevent hand-arm vibration syndrome.

Whole-Body Vibration

What causes human vibration?

Whole-body vibration which, according to ISO 2631, are vibrations from machinery, vehicles, and industrial processes that have an impact on people's comfort, activities, and health. This type of human vibration measurement is done with sensors that are flat and in the shape of a seat pad. It is placed directly on the seat cushion, floor, or fastened to the rear of the seat.
