An example of non-contact measurement of torsional vibration using a laser in-plane velocity meter.

【overview】
In this workshop, we will introduce an example of non-contact measurement of torsional vibration using a laser in-plane velocometer. Recently, in the development of xEVs, the weight reduction of drive units and vehicle bodies has been progressing. As vehicle inertia changes with weight reduction, it has become important to re-evaluate the impact on the drivetrain's torsional transmission system. A laser in-plane velocometer can measure the peripheral speed of rotating parts such as drive shafts non-contact. Furthermore, since the difference between the measured values of two sensors can be calculated, torsional vibration can be measured without being affected by the measurement system.
