Abstract

The invention discloses a testing machine of small-load attacking wear. Stand board is fixed behind base. Exciter with a downward roof bar is equipped in front of top of. End of exciter roof bar connects piezoelectric impedance sensor and upper sample holding device in turn. Lower sample holding device is fixed under the sample holding device on the base. The testing machine suits for tests with small-load attacking, which has merits including high automatic degree, stable working load, good persistent-working ability, high precision and good repeatability of test data.

Description

technical field [0001] The invention relates to an impact wear tester, in particular to an impact wear tester under small load. Background technique [0002] Impact wear is the surface wear caused by repeated dynamic contact and impact between a solid surface and another solid surface. Many components in various types of machinery are subjected to different degrees of impact wear, such as electromagnetic contact devices, die concave and convex dies, tool notches, forging hammers, etc. The impact load will cause damage to the contact surface, and in severe cases, it will lead to failure of components. Among the various wear-induced failures, impact wear has the greatest impact on materials and is currently the least understood. This is due to the complexity of the impact wear problem on the one hand, and the lack of impact wear test equipment on the other hand. [0003] Existing impact and wear testing machines can be divided into: free fall type, lever mechanism type, cyl...
