Kaji Numerik Pengaruh Beban Dinamik Terhadap Tekanan Dan Ketebalan Lapisan Film Pada Cylindrical Roller Bearing Menggunakan Metode Beda Hingga

Roller bearings are one type of bearing (cylindrical) that use a roll or cylindrical
shape as a friction damper on the bearing. Dynamic bearing is one factor
influencing performance of roller bearing. One source of dynamic load on a
bearing is vibration. This study examines how the influence of dynamic loads on
the film thickness formed and the generated pressure that occurs in contact between
the cylindrical roller and the inner ring. The dynamic load examined in this study
is the fluctuation of the load generated by external influence of vibration, which
theoretically changes the actual load acting on the sinusoidal fluctuating bearings.
The simulation begins with a static load condition, the results of this static
simulation are used for dynamic load simulation in solving the Reynolds transient
equation in which the influence of time cannot be ignored anymore. The finite
difference method with a central-difference scheme is used to solve the Reynolds
equation. The results showed that the film thickness and the pressure that occurs
changes every time. The greater the amplitude of the excitation the greater the
pressure applied to the contact, the thinner the film formed. The frequency of
excitation affects the number of repetitions of loads that work at one particular
time.
