Analisis Stress dan Friction pada Alat Uji Model Pin-on-Disc dengan Berbagai Pembebanan

Abstract

This study aims to analyse the effect of loading variations on the stress and friction coefficient on the Pin-on-Disc model test equipment. The research methods include numerical simulation using ANSYS Transient Structural software and experimental testing with Pin-on-Disc test equipment equipped with a friction load cell. The load variations used were 100 grams, 300 grams, 500 grams, 700 grams, and 900 grams with a fixed disc rotational speed of 600 rpm. The simulation results showed that the stress value on the pin decreased very little as the load increased, from 1.1350 Pa (100 grams) to 1.1330 Pa (900 grams). Meanwhile, the simulated friction coefficient decreased from 1.347 (100 grams) to 0.1487 (900 grams). In the experimental tests, the coefficient of friction also showed a decreasing trend, although with a higher absolute value. In addition, the temperature distribution at the contact surface increased as the load increased, with the highest temperature reaching 37.69°C at a load of 900 grams. The conclusion of this study is that an increase in load leads to a decrease in stress and coefficient of friction, as well as an increase in temperature at the contact surface. These results can serve as a reference for material optimisation and tribological test equipment design in industrial applications.
