Kaji Numerik Pengaruh Bio-Based Lubricant Terhadap Ketebalan Lapisan Film Dan Tekanan Hidrodinamik Pada Journal Bearing Menggunakan Finite Difference Method

---

ABSTRACT
In journal bearings, there is a contact between the shaft and the bearing. The
impact that occurs on these contacts is friction which causes wear on the bearing
material. This research was conducted to see the effect of bio-based lubricants on
the distribution of hydrodynamic pressure and the film thickness on the journal
bearings. The numerical assessment was carried out for this study using one of
the numerical methods, namely the finite difference method. The finite difference
method is a method commonly used to solve the Reynolds equation in which this
equation is used to calculate the pressure distribution. The FDM discretization
scheme use in this simulation was central-difference because it has a more
accurate value approach to the actual value than using other schemes. This
research was conducted by varying several parameters with different results. The
different types of bio-based lubricants affect the pressure distribution, but not the
film thickness which can only be measured by the eccentricity ratio. It was
obtained from several bio-based lubricants, namely coconut oil, olive oil, and
palm oil that the better lubricant to use is coconut oil because it produces less
pressure for other types of lubricants.
