Abstract

The invention discloses a magnetorheological elastomer gasket and a control device thereof. The magnetorheological elastomer gasket is composed of a rubber substrate and micro-sized ferromagnetic particles and has the variable rigidity characteristic. The control device of the gasket mainly comprises electromagnets, an adjustable power supply, a pressure sensor and a controller which jointly compose a feedback control loop, and the rigidity of the magnetorheological elastomer gasket can be adjusted in real time. The magnetorheological elastomer gasket and the control device thereof are simplein structure and low in cost, stress and deformation self compensation of the gasket can be achieved, the stability of fasteners and the airtightness of a pipeline or valve connector can be improved,the service life of the gasket is prolonged, and the magnetorheological elastomer gasket and the control device thereof are particularly suitable for environments with high requirements for safety andprecision.

Description

technical field [0001] The invention belongs to the field of elastomer gaskets, and in particular relates to a magneto-rheological elastomer gasket and a control device thereof. Background technique [0002] Elastomer gaskets are generally widely used in various mechanical equipment to play the role of liner, seal, buffer and so on. For example, gaskets are used in fasteners to cushion and cushion nuts, and gaskets are used at the interface of pipes or valve bodies, which can not only reduce damage caused by rigid body vibration, but also play a sealing role to prevent fluid seepage. leak. In practical applications, ordinary elastomer gaskets have poor stability and short service life. Under various forms of load or fluid corrosion, they are easy to age, relax, deform, and fail, causing failures to mechanical equipment in production. If these devices are used in high-pressure containers, high-pressure pipelines or nuclear power plants, it will bring huge harm and loss. C...
