Abstract

The invention discloses a condition monitoring based passive magneto rheological vibration damper which comprises a magneto rheological vibration damper, a vibrational energy collector, an energy recovery control module and a condition monitoring system, wherein the vibrational energy collector adopts a permanent magnet linear generator formed by an Halbach array based permanent magnet runner and a coil winding stator group, and is used for converting kinetic energy generated by vibrational source excitation into electrical energy; the energy recovery control module is used for storing the electrical energy converted by the vibrational energy collector; the condition monitoring system is used for adjusting the current input into the excitation coil in real time by the energy recovery control module, so as to change the output damping force intensity and realize passive control for the external vibration. The vibration damper provided by the invention has the advantages of small size, high efficiency, energy conservation, convenience in mounting and maintenance, reliable system and the like.

Description

technical field [0001] The invention relates to a magnetorheological shock absorber, in particular to a passive magnetorheological shock absorber capable of state monitoring. Background technique [0002] Under the action of a magnetic field, magnetorheological fluid can transform from a free-flowing linear viscoelastic liquid to a viscoplastic body with a high shear yield stress within milliseconds. The magneto-rheological shock absorber made by using this characteristic has the characteristics of simple structure, wide dynamic range, fast response speed, low energy consumption and strong bearing capacity, and is a very ideal vibration control device. [0003] The traditional magnetorheological semi-active suspension system consists of magnetorheological shock absorbers, sensors, controllers and related circuits. On the one hand, it needs an external power supply to power the magnetorheological shock absorbers to drive the electromagnetic coils in the shock absorbers. Gene...
