Behavior of lab scale scissor dry friction damper under harmonic loading

Abstract

The behavior of scissor action dry friction damper under harmonic loading has been presented. Finite element model was developed in PTC CREO and then imported in ANSYS to check the response with varying values of normal force (100N, 120N and 150N). A constant force of 20N is applied to excite the damper harmonically. Moreover the experiments are performed after fabricating the device to validate the results. A separate set of apparatus was used to calculate the coefficient of friction between the contacting surfaces.
