Abstract

This research, the natural frequency and excitation frequency values for resonance have been identified.
The analysis was carried out using the eigenvalue matrix method, where the mass and stiffness variables are used to
determine the natural frequency values in the propulsion system. In addition, the finite element method was also applied
to compare the natural frequency values obtained mathematically. The excitation frequency in the system is generated
from the main engine rotation. The modeling results show three natural frequency values, namely 0.3379 rad/s, 4.6663
rad/s and 82.0225 rad/s. The resulting excitation frequency comes from four variations of engine rotation, namely rpm,
65 rpm, 100 rpm, 106 rpm, and 115 rpm. From the comparison between the excitation frequency and the natural
frequency, it is known that the propulsion system does not experience resonance
