Abstract

The invention discloses an automatic control type inerter. The active control type inerter mainly comprises a screw transmission pair formed by a screw rod and a nut as well as a gear meshing transmission pair formed by outer teeth of a planet gear and inner teeth of an outer gear ring. A motor is used as an active control element and adjusts the output force of the inerter, so that the inerter is adapted to variable vibration input, and the application field of the inerter is broadened; the inertia function is realized through a planet fly wheel set, and the inertance of the inerter is effectively increased through revolution and rotation of a planet gear train.

Description

technical field [0001] The invention relates to an inerter, in particular to an actively controlled inerter. Background technique [0002] The output force of the inerter is proportional to the relative acceleration at both ends, which can realize the dynamic characteristics of a large mass with a small mass, which greatly broadens the structural form of vibration control. However, the inerter is an element with both ends. When used as an inertial element in applications such as dynamic vibration absorbers, its action form is very different from that of a single-mass body, which inevitably causes problems such as narrowing of the vibration reduction frequency band. In addition, the inertial coefficient of an inerter with a fixed structure is correspondingly determined and unchanged, which cannot adapt to changing vibration input. Furthermore, the conventional single-flywheel inerter only utilizes the moment of inertia of a single flywheel, and the inertia coefficient is lim...
