[0002] The magneto-rheological damper is an intelligent damping device. The existing rod-type magneto-rheological damper mostly adopts a piston and cylinder structure, and the piston is mostly a cylinder made of magnetically conductive metal. The viscosity of the magnetorheological medium between the cylinders is used to adjust the output damping force; this type of damper has a complex structure and requires high precision for the piston and the cylinder. The magnetorheological damper with a cylindrical piston structure is due to the The mass is large and the gap between the piston and the cylinder is small, so it cannot be used in occasions such as suspension and other eccen

The invention discloses a suspension type magneto-rheological damper and system. The damper comprises a damping bar and a magnetic field, the damping bar is made of magneto-rheological elastic materials, the magnetic field acts on the damping bar, the strength of the magnetic field can be adjusted, the upper end of the damping bar is capable of hanging a suspended component, and a connecting component used for connecting a device needing to be damped is arranged at the lower end of the damping bar. The damping bar made of the magneto-rheological elastic materials is adopted for forming the suspension type magneto-rheological damper, the overall structure is simple, the weight is low, the inertia is small, the purpose that the elasticity can be adjusted when the damper is suspended and used can be achieved by utilizing the characteristic of adjustable elasticity of the magneto-rheological elastic damping materials, the elastic coefficient can be adjusted according to different vibration and different weight of a suspended device, the high-frequency and small-amplitude vibration can be effectively and specifically damped, the suspension type magneto-rheological damper is suitable for the detection and production operation occasions where the requirement for precision is high and the suspension using is needed, and detecting precision and operation stability are guaranteed.
Description
technical field [0001] The invention relates to a magnetorheological damping device, in particular to a suspension magnetorheological damper and a system thereof which can ensure that measuring instruments are not disturbed by external vibrations. Background technique [0002] The magneto-rheological damper is an intelligent damping device. The existing rod-type magneto-rheological damper mostly adopts a piston and cylinder structure, and the piston is mostly a cylinder made of magnetically conductive metal. The viscosity of the magnetorheological medium between the cylinders is used to adjust the output damping force; this type of damper has a complex structure and requires high precision for the piston and the cylinder. The magnetorheological damper with a cylindrical piston structure is due to the The mass is large and the gap between the piston and the cylinder is small, so it cannot be used in occasions such as suspension and other eccentric forces; and it has a large m...
