Vibration measurement according to ISO, the General vibration local vibration

The term vibration means the fluctuation of solids/ maximum 20 Hz processing the frequency perceived by the human body through touch. Installed that each design (any elastic body) if it is derived from the provisions equilibrium is characterized by a certain period of oscillation and frequency.

When the impact on the design (hardware) force which will be periodically to change, begin forced oscillations. The force causing them called disturbing.

When two frequencies (disturbing force and natural oscillations of the amplitude) are the same, the vibrations of construction (equipment) starts to increase. The result resonance occurs. It creates vibration and dangerous for construction (equipment). At the same time, with increasing amplitude, and increases deformation, which ultimately leads to an increase in the tension machine.

If will decrease the efficiency of the mechanisms, we will begin accelerated wear of parts will be necessary in frequent repairs, broken process, and readings of the measuring equipment. And the end result - failure (destruction) of equipment (design).

Failure the working mechanism can lead to injury of the person administering it equipment.

However even without damage to equipment vibration is dangerous for the human body.

Common vibration is transmitted to the entire body. It is called as a result of work tools, machines and other process equipment when shaken seat (table, floor), on which he sits (is) working.

Local vibrations that are transmitted to separate parts of the human body. Mainly on hands, because they direct contact with vibrating sources. As an example you can bring hammers, boring machines, grinding equipment and other manual machines. Possible combination of both types of vibration.

In what is the danger? Imagine that the internal organs (heart, stomach) is the vibrating system connected by elastic elements having different concentrated masses and the oscillation frequency of 6-9 Hz. When people start influence of external waves with the same frequencies of possible resonance the fluctuations of bodies. There is a danger of displacement or damage.

In the result over time:

· Worsens blood flow to the fingers, forearms, heart vessels;

· Disturbed skin sensitivity, activities heart, nervous system;

· Deformed joints (decreased mobility),

· Worse hearing, sight, increase blood pressure.

When intensive exposure to vibration may occur vibration disease, which hard cured.

So this phenomenon must be fought, and regularly measuring vibration according to ISO. In this issue the company BALTECH adheres to international standard ISO 10816. It is accepted by all the countries of the CIS.

Standard involves the use of three main vibropressov: move (readout microns), velocity (mm/s) acceleration (m/S2). In this the standard is given the procedure for establishing the maximum values specified parameters.

Our Department of technical service (OTS) performing measurement of vibration on the ISO, follow these principles.

Practice showed that in most cases, it ensures satisfactory performance industrial equipment. Ensured safe operation of the machine and the lack of vibration on adjacent equipment.

For accurate measurements of vibration according to GOST we can offer the "VibroPoint". From vibroluxes (BALTECH VP-3405-2) to the vibration meter-thermometer-balancer ("PROTON-Balance-II").
