| Summary: | To understand a vibration testing process, a beginner needs <br />
practical experience in this activity by conducting a vibration <br />
measurement ofa system. He will use complex instrumentations and <br />
therefore, `endanger\' expensive devices. In order to avoid the <br />
problems, a teaching aid is needed by which a vibration testing can <br />
be done through a computer-based simulation. <br />
The purpose of this research is to develop a A1ATL.4B-based <br />
simulation program which able someone to analyze one, two, and <br />
multi-degree of freedom vibration systems. This program also <br />
provides vibration analysis results, such as free and forced <br />
vibration responses in time and frequency domain, frequency <br />
response function (FRF) and coherence function, averaged FRF <br />
and coherence function, and correlation functions. <br />
In this research, a two degree offreedom vibration system <br />
under random excitation will be analyzed by using the program. <br />
The simulation results display FRF of the system in the presence of <br />
noise excitation. By using this program, therefore, one can obtain <br />
the understanding of vibration testing process and the knowledge <br />
about important notion that should be considered to obtain more <br />
reliable measurement results. |
