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.
