Torsional Vibration

LMS offers a complete solution for accurate measurements of the torsional variations of one or multiple shafts. The LMS SCADAS Mobile torsional vibration module ( SCM-RV4) acquires, offline or in real-time, up to 4 tacho pulse streams at a high pulse rate. These pulses are translated into accurate angular velocity and displacement time histories at high aliasing-free bandwidth. Both TTL as well as analogue, unconditioned pulse streams are supported. Alternatively, the RV4 module is able to capture up to two incremental encoder signals. The LMS Test.Lab Torsional Vibration Analysis software lets engineers analyze the torsional vibrations of rotating machinery with single or multiple shafts. RPM order sections can be extracted from fixed sampled frequency spectra as well as from data sampled synchronously with RPM, giving leakage-free, razor-sharp order cuts. The software is able to perform and process real-time observations of shaft angular displacements, speed or acceleration, torsion over shafts, belt transmission errors or other specific metrics. Acquired tacho-data can be corrected for missing or double pulses, or for unevenly spread pulses ( pitch correction) . Results can be viewed alternatively in RMS or peak format in order to match the legacy data. To correlate torsional vibration phenomena with other NVH-related problems, the LMS solution simultaneously records tacho channels signals with other quantities such as acceleration, pressure or strain. A correct test set-up is crucial to accurately measure torsional vibrations. Faster and simpler set-ups are made possible with the LMS Test.Lab zebra-tape correction algorithm. Using tacho-pulse streams from a zebra-tape wrapped around the rotating shaft, the LMS Test.Lab algorithm is able to correct the error generated by the butt-joint ( the point where the two sides of the zebra-tape come together Software engineering memiliki misi menyediakan quality engineering software untuk para engineer sehingga mereka dapat lebih produktif dalam pekerjaannya.
