The LMS Test.Lab Torsional Vibration Analysis system provides a complete solution to determine which noises are caused by torsional vibrations, such as the structure-born noise of a crankshaft.
Torsional vibration analysis is key to the NVH performance of transmission equipment and engine- and powertrains, as well as to vehicle development. LMS Test.Lab Torsional Vibration Analysis allows engineers to measure torsional vibration signals which are found in mechanical products, such as powertrains, gearboxes, jet engines, outboard motors, engines in gardening equipment, washing machines, etc.
Torsional vibrations are oscillatory angular motions that cause twisting in shaft sections and couplings of rotating machinery. These fluctuations are superimposed on the steady running speed. They result in a broad range of problems that impact durability, NVH comfort and interior noise. For instance, during engine start and stop, they can cause clutch judder, a low frequent vibration (5-20 Hz) that occurs during the clutch engagement process.
LMS Test.Lab Torsional Vibration Analysis provides a complete solution to quantify and qualify the influence of torsional vibration on noise and vibration performance.
