Buffering device with efficient energy absorbing performance

Abstract

The invention discloses a buffering device with efficient energy-absorbing performance. The buffering device comprises a magneto-rheological torsion damper and a motion conversion mechanism used for converting linear motion generated by vibration into rotation to make the magneto-rheological torsion damper inhibit the vibration; the motion converting mechanism is a ball screw rod pair structure and comprises a screw rod used for bearing a vibration load and a nut used for converting linear motion of the screw rod into rotation, and the nut is fixedly connected to a rotary shaft of the magneto-rheological torsion damper and rotates synchronously; the screw rod coaxially penetrates through the rotary shaft and is cooperatively connected with the nut. Reciprocating vibration shock can be converted into stable rotation, and stable damping in the whole process is achieved; meanwhile, the overall size of the device can be effectively reduced, the design is simple, and requirements of precision and miniaturization for an instrument are met.

Description

technical field [0001] The invention relates to the field of structure vibration shock buffer control, in particular to a buffer device with high-efficiency energy absorption characteristics. Background technique [0002] With the continuous development and progress of current technology, the vibration generated by the mechanical power system during operation and external energy input seriously affects the smooth operation of the instrument. At present, adding a damping device is one of the measures to effectively suppress vibration; however, due to the complexity of the excitation, it is difficult for the traditional passive vibration isolation device to obtain good damping characteristics; although the effect of active control is better, the structure is complex and the energy consumption is large. Therefore, there is a need for a vibration-absorbing and shock-isolating device with a simple structure and good damping characteristics. The magneto-rheological torsional vibr...

Problems solved by technology

If the magnetorheological torsional damper is to be applied in the occasion of linear reciprocating vibration, it generally needs to cooperate with the motion conversion mechanism. Because the existing magnetorheological torsional damper and the motion conversion mechanism are installed separately, the installation size is too large, and The design is complex, and it is difficult to meet the requirements of precision and miniaturization of the instrument
