torsional vibration - Opis:
- The rotation of a crankshaft in piston combustion engines results from the acting of tangential forces on the crank, whose value changes with the change of the angle of shaft rotation. This results in torsional vibrations. These vibrations become especially dangerous when the frequency of changes of any components of tangential force is near or equal to the natural frequency of the shaft. It leads to resonant amplification of vibration amplitude and to exceeding the limit values of the angle of shaft torsion. Most often in such cases, various types of torsional vibration dampers are used. In automotive industry, these are usually rubber vibration dampers. Typical torsional vibration damper is an example of a resonant damper, which is designed for the most dangerous resonant frequency of the crankshaft related to the first form of vibration for which the torsional vibrations usually have the greatest amplitude. The design of such a damper involves choosing the inertia moment of the flywheel and the parameters of viscous-elastic element. The article describes the model and the simulation research, which allowed for creating the procedure of designing rubber dampers of torsional vibrations. This procedure can help to reduce the costs of operation tests for the design of optimal torsional vibration damper.
