Analisis pengaruh perbedaan koefisien gesekan statis dan kinetis terhadap gerakan stick-slip menggunakan bahan viskoelastis

Abstract

Stick-slip motion in a mechanical system is undesirable because it has
negative effects on the performances such as positioning errors and excessive wear. Stick-slip
motion is caused by various parameters such as the difference between static and kinetic
coefficient of friction, âs-âk. In this study, the effect of the difference between static and
kinetic coefficient of friction, âs-âk, on stick-slip occurrence is numerically simulated and
experimentally tested using a mass-slider system. The objective is to find out the effect of âs-âk
parameter on the stick-slip propensity, qualitatively, using viskoelastic material. The results
indicated that the amplitude of the stick- slip motion increased significantly with the
increased value of âs-âk
parameter.
