Measurement Techniques

Tasks
The measurement-technological coverage of oscilation emissions e.g. immissions as a basis for vibration technological measurement to observe legally laid down limit values.

As can be seen, different limit values must be observed, depending on the location of the machine. This standard aims at laying down principles according to which mechanical shocks can be progno-sticated or measured in buildings, enabling the determination of effects of vibrations on human beings and building construction. Another relevant example for the necessity of a vibration analysis is the mounting of high-precision 3 D-measurement machines as well as of other testing, measuring or grinding machines. As a rule, measurement-tests must be carried out on envisaged locations for such machines to ensure that local ground oscillations do not exceed permissible values.

To this end oscillation accelerations within a given frequency spectrum (1–100 Hz) are taken down, because a simple summation value measurement would give only an approximate indication of the exact environmental conditions. The evaluation of the power-path signals takes place with a Fast Fourier analyser, indicating the measured value for each frequency of the spectrum (vibration acceleration in g). Should the interferences (vibration magnitude) be outside the admissible range, a suitable insulation can be worked out with the assistance of our computer calculation programs.
