The Influence Of Temperature And Lubrication Variation On The Dimension Change In Ring Compression Test Using Ansys Software

Abstract

Abstract The objective of the study is to identify the influence of temperature and lubrication influence on Ring Compression Test. Within the study, a quasi-experiment was conduct using ANSYS software. The simulation of Ring Compression Test was conducted by varying the temperature (200°C, 300°C and 400°C) and the lubrication (0.48, 0.60 and 0.88). The dependent parameters in the simulation of Ring Compression Test were as follows: hot forging job, heat transfer coefficient 5 W/(m2K), collision velocity 0.008333 m/s and top die movement depth 7 mm (50%). From the results of the study, it might be identified that temperature variation does not have significant influence of dimension change while. On the other hand, the results of lubrication variation show that the higher the collision coefficient is the lower the diameter on the Ring Compression Test will be.
