Die Drehschwingung oder Torsionsschwingung ist eine in der Technik wichtige mechanische Schwingung. Im Gegensatz zur translatorischen Schwingung erfolgt bei der Drehschwingung eine Schwingung um den rotatorischen Freiheitsgrad eines Systems.
, 비틀림 진동은 가늘고 긴 물체에 비틀림 힘을 작용하여 비틀어진 물체가 원래 상태로 되돌아가려는 복원력이 작용할 때 일어나는 진동이다. 가늘고 긴 물체에 비틀림을 작용시키면 비틀림 각이 생기고 그에 비례하는 복원력이 작용하는데, 이 복원력에 의한 진동이 비틀림 진동이다. 예를 들어 줄에 돌을 달고 정지하고 있는 상태에서 줄을 비틀면 돌은 철사가 원상태로 돌아가려고 하는 힘 N을 받는다. N은 N=cθ이며, 세타는 비틀림 각, c는 비틀림 상수이다.

, Torsional vibration is angular vibration o … Torsional vibration is angular vibration of an object—commonly a shaft along its axis of rotation. Torsional vibration is often a concern in power transmission systems using rotating shafts or couplings where it can cause failures if not controlled. A second effect of torsional vibrations applies to passenger cars. Torsional vibrations can lead to seat vibrations or noise at certain speeds. Both reduce the comfort. In ideal power generation, or transmission, systems using rotating parts, not only the torques applied or reacted are "smooth" leading to constant speeds, but also the rotating plane where the power is generated (or input) and the plane it is taken out (output) are the same. In reality this is not the case. The torques generated may not be smooth (e.g., internal combustion engines) or the component being driven may not react to the torque smoothly (e.g., reciprocating compressors), and the power generating plane is normally at some distance to the power takeoff plane. Also, the components transmitting the torque can generate non-smooth or alternating torques (e.g., elastic drive belts, worn gears, misaligned shafts). Because no material can be infinitely stiff, these alternating torques applied at some distance on a shaft cause twisting vibration about the axis of rotation.ting vibration about the axis of rotation.
