Numerical Study on the Mechanism of Friction Lining with Micro-Elliptical Texture in Safety Brake of Nuclear Power Plant

The frictional performance of safety brake used in nuclear power plant affects the safety and economy of nuclear power plant equipment. In this study, the micro-ellipse texture was applied to the friction lining of safety brake. The mechanism of electromagnetic brake’s friction lining with elliptical texture was studied by numerical method. The analysis model of friction lining with micro-ellipse texture was established, at the same time, the pressure distribution on the surface of the friction lining was solved by the finite element method. The influence of ellipse inclination angle on the pressure distribution was studied, which provided the basis for perfecting the design of the friction lining with elliptical texture in the electromagnetic brake.
