Investigation About The Abrasion And The Wear-ability Of Bionic Non-smooth Friction Lining

Friction lining ( brake lining) is a frictional part used in the brake rigging of the train, if it wears severely, it will result in some problems, such as braking invalidation of the train, potential safety hazard and the severe waster of the resource. With the rapid development of the industry and the technology, developing the exterior wear resistance properties ( abrasion resistance) of the part and reducing the frictional wear have been an important subject starving for solution. Previously, the research of the brake slice focused on the composing of the materials, they have gained some production, but there were some deficiency and limitation. Recently, research on bionics have found that soil animals such as dung beetle and pangolin can shuttle in the soil without any damnification, it indicates that configuration of the non-smooth surface has wear resistance, the forming of non-smooth configuration of the biologic surface relates to not only species inheritance but also biologic habits and conditions directly, it is a special configuration which is formed by the biology to adjust the existent environment, it proved a new idea and foundation.Investigation of the friction lining on engine bench tests needs a mass of manpower and material resources, it costs too much and test period is too long, so it doesn't adapt to test and optimize the wear-ability of various configurations of the non-smooth ,therefore ,this paper adopts a method integrating model test with computer simulation, and provides important theory foundation and reference.This paper designed two kinds of configurations: concave and through holes, experimented with the wear resistance of the concave,through holes and friction couples.
