The manufacturing industries carry many operations that generate unwanted noise and vibrations. Such phenomenons are more than just parasites; they can alter the production quality, especially in machining.
Noise and vibration have multiple sources in a machine. They may come from structural or torsional resonance, transmission effects as well as inappropriate force and speed. OROS provides a complete solution line to understand, localize and reject these interferences. Based on multi-analysis capabilities, the roots of issues are clear and easily controlled.
Absorbing and damping mounts are the components through which the vibration energy is transmitted between the motor and the rest of the optical parts: their properties dimensions and positions are key and should be determined with care. The techniques used are cross spectrum, transfer functions, damping, as well as ODS.
To produce high quality mechanics, high quality machining is required. Machine tools like any other high speed machines have a potential rich vibration content. It is essential to monitor and optimize surface fluctuations generated by the cutting tool vibrations in order to avoid any possible defect in the quality of the manufactured parts.
Modal Analysis is one of the key step when testing machines' structures and components: it will determine their structural characteristics and so, will define how they will react to operating excitations. Shaker or impact hammer excitations can be used to capture the experimental datasets: the final stage is the actual OROS Modal analysis.
Electric motors and their transmissions are subject to rotational speed fluctuations and resonances. These torsional motions may have important effects;
fatigue, life time reduction, malfunction or low quality machined parts source may be hidden in the motors, gears, belts or chains of your machine tool.
The OROS Torsional inputs and associated software offer the ideal toolset for identifying the source and path of rotational fluctuation into your machine kinematic.
Gear box vibrations have high frequency content which can impact machine’s parts quality. A fi rst step is to analyze them using the standard FFT analysis.
One can get further with tools such as cepstrum, kurtosis and harmonic markers provided by the OROS FFT-Diagnostics tool
