The friction and wear samples are ground down using SiC abrasive paper from 60 to 2000 granulation and polished before the test to ensure the accuracy of the test. The upper friction sub is made of Si 3 N 4 balls with a normal loading load of 10 N, a reciprocating speed of 120 mm/min, a displacement amplitude of 7 mm and a working time of 60 . In this study, piezoelectric elements were added to a reciprocating friction test bench to harvest friction-induced vibration energy. Parameters such as vibration acceleration, noise, and voltage signals of the system were measured and analyzed. The results show that the piezoelectric elements can not only collect vibration energy but also suppress friction-induced .

Featuring a patented test principle, the SRV®5 tribometer allows for high-precision friction and wear tests of lubricants, materials, coatings and components. The SRV®5 tribometer offers a wide range of practice-relevant test concepts, even in its standard configuration with oscillation. The vertical load, friction ball diameter and reciprocating movement frequency (friction speed) are selected as the experiment factors. The cutting tools was installed in the special designed fixture on a reciprocating movement wear test machine. The wear depth increases with the increase in the Z-load, ball diameter and frequency.
