Measurement of vibration, classification of vibration, vibration transfer

In agriculture, industry, transport and other areas there are many harmful factors. One of them is a common vibration that can adversely affect the efficiency man and his health. In some cases vibration can lead to the emergence of vibration disease development.

Characterized by overall vibration spectrum frequency (Hz) the velocity (m/s) and acceleration (m/S2). Except these parameters and their use logarithmic levels (dB).

Overall vibration divided into 2 classes.

Transfer total vibration is carried out through the support surface of the person. If he sits – through the buttocks, if necessary – of the foot. Category 3:

1. Transport. Refers to the car/s. cars, tractors, etc.;

2. Transport-technological. Have in mind cranes (construction, industrial), manufacturing floor transport mining machine;

3. Technology. Pumps, fans, stationary equipment of various industries.

In this case measurement of vibration is performed by:

· The vertical axis Z;

· The horizontal axis X (chest-back);

· The horizontal axis Y (shoulder-shoulder).

The equipment has to work in the passport/standard mode by:

· Operations;

· Speed;

· Processed object;

· Load, etc.

When monitoring the General vibration of all the sources of transmission for the workplace should be included. Mounting position (measurement point) vibration sensor must be placed in locations where there is contact with the body of the operator:

· Seat, the floor of the working area, the working area;

· Contact expert with the arms or the control levers.

Vibration sensor should be mounted on level ground in 3rd mutually perpendicular directions (Z, X, Y). Installing the vibration sensor in a selected control point include a vibration meter for carrying out the necessary measurements, performing operations according to the instructions. For the overall technological vibration requires 6 counts, total transport (transport technology) – 30 plus the subsequent processing.

To measure vibration, you will need modern appliances.

To measure vibration the company BALTECH offers vibroshock BALTECH VP-3405, but if you want to measure the other two vibroplate (displacement or acceleration), we can buy it upgraded version (BALTECH VP-3405-2) or the vibration meter BALTECH VP-3410 series "VibroPoint". The first two devices, the sensor built into the body, and the third is placed on cable and features a magnetic clip.

All these devices comply with interstate ISO 10816.

If you do not want to conduct their own operations and prefer to entrust the measurement of total vibration specialized enterprises, offers technical service BALTECH, which will perform vibration diagnostics and vibration control of any dynamic rotary equipment ranging from electric motors to bearings (rolling slide).

If you want independently perform measurements, but your staff is not trained, we offer visit our "Training center qualification and training BALTECH", where experienced specialists conducts training courses on the rules of measurement of vibration using vibration meters and analysers.
