Abstract

The invention discloses a torsional vibration energy storage and release device. The torsional vibration energy storage and release device comprises a transmission shaft. The left end and the right end of the transmission shaft are rotationally connected to bearing blocks through rolling bearings respectively. A bearing end cover for limiting the position of each rolling bearing is fixed to the corresponding bearing block. A push mechanism is arranged at the bottom of each bearing block. A pressure plate is fixed to the middle of the transmission shaft. In conclusion, the torsional vibration energy storage and release device can achieve the effective damping effect on a system on one hand, and is mainly used for conversion between self-excited vibration and forced vibration in a vibrationtest platform on the other hand; when forced vibration happens to the system, the micro-amplitude torsional vibration energy of the system is collected by the device; and after forced vibration stops,because of a clutch structure, the collected energy is released inside the system, and the experimental system can have own self-excited torsional vibration.

Description

technical field [0001] The invention belongs to the technical field of nonlinear vibration energy testing, and in particular relates to a torsional vibration energy storage and release device. Background technique [0002] Torsional vibration is a common phenomenon in the working process of rotating machinery, and shafting is one of the most fundamental structures in all rotating machinery. At present, the research on torsional vibration of shafting is mainly carried out. The generation of torsional vibration is usually caused by the change of the torque acting on the shaft. When the load or driving force of the shaft changes suddenly, the torque acting on the shaft changes to a certain extent, and the torsional vibration phenomenon occurs on the shaft. During the operation of rotating machinery, the occurrence of torsional vibration will cause great harm to the safety of the entire system. It will generate dynamic stress inside the system, and the dynamic stress value will ...
