Torsion Springs exert force along a circular path, providing a twist or a torque. Torsion springs include helical and bar springs. These springs feature a shaft spring and drum assembly that cannot break & distributes the doors weight more evenly.
Torsional Analysis is performed on an automotive engine, which is attached to an engine dynamometer. Torsional analysis program uses a multi-section, lumped-inertia, torsional rotor model to compute undamped torsional eigenvalues, normalized eigenvectors and transient torsional damped response of a multiply geared rotor shaft.
Torsional couplings solve torsional vibration problems typical of those found in diesel engine applications. It dampens torsional vibrations and tunes the system to have critical speeds outside the operating range. There are different types of torsional couplings. Most couplings use a rubber element to transmit torque between two hubs. The rubber damps any vibrations moving from one shaft to the other. Torsional couplings are made to adapt to shafts, flywheels, or universal joints.
