The special tribo-electdc tester with high sliding speed and electric current was developed,which mail working parameters are, current density up to 2.5 A/mm~2, the sliding speed 100 m/s,the load over 500 N (3.2 MPa) and the pulsant strike pressure within 20 N. This testersuccessfully simulates the tribological and electric properties of strip materials. 2, By using the above tester, study on tdbological properties and carrying currentperformances of copper-base powder metallurgy material and metal impregnation carbonmaterial are carded out.

本论文开展的主要研究内容和所取得的成果如下： 1、首次开发了大电流、高速度和重载荷的载流摩擦磨损专用试验机，能够稳定提供恒定交流电流密度2.5 A／mm~2，相对滑动速度100 m／s(12000 r／min)，载荷可达500 N(3.2MPa)，脉动冲击载荷可达20 N，为研究提速接触网和滑板的高速载流摩擦学特性及其机理，以及开发新型高耐磨性、高载流性能滑板材料提供了先进可靠的试验手段(该机已获得一项实用新型专利，ZL 2006 2 0096036.5)。
