WebA piezoactuator is used to impose fretting motion, and a tri-axial load cell is used to measure tangential force as well as possible misalignment forces. A laser nanosensor is employed to measure the relative motion between the joint halves. No post-processing and filtering of the data is needed to obtain the fretting response using this apparatus.
WebMar 30, 2024 · Fretting is a phenomenon that occurs when two contacting surfaces are subjected to oscillating tangential forces. Zones of microslip develop along the contact surface where sliding occurs, leading to considerable surface damage. As a result, two main effects can be observed: Wear of the surfaces; A considerable reduction in fatigue life. shun vs scylaWebOct 1, 2011 · An experimental apparatus designed specifically for fretting experiments on mechanical lap joints is presented.
