三维互穿结构Cu-W触头接触器合闸弹跳抑制
3-D Interpenetrating Structure Cu-W Electrical Contact Contactor Closing Bounce Suppression
摘要
Abstract
To effectively suppress contactor bounce during closure,this study utilizes 3D printing and melt infiltration to fabricate Cu-W contact materials with cubic(CB)and rhombic dodecahedron(RD)three-dimensional interpenetrating structures.The bounce mechanism is analyzed through material structural parameters and vibration absorption characteristics.Applying Hertz contact theory and its extensions,we investigate energy loss during contact collisions while testing stress-strain curves and damping properties of three Cu-W contact types.Using a specialized bounce detection apparatus,we capture closing bounce trajectories for different structural contacts under varying parameters.A detailed contactor model evaluates bounce suppression performance among the Cu-W structures.Results demonstrate that structural modifications alter the contacts'mechanical and damping properties,with RD-structured Cu-W contacts exhibiting superior performance:higher damping coefficients,greater compressive deformation,enhanced internal friction,and excellent energy absorption capacity that effectively dissipates collision energy to minimize bounce.Consequently,RD-structured Cu-W contacts achieve optimal anti-bounce performance during high-speed closure.Implementing RD-structured Cu-W contacts significantly suppresses contact bounce,thereby improving contactor reliability and operational lifespan.关键词
