Nizam Dahalan, supervisor Mechanical engineering Also available in printed version Vibration in structures can cause malfunctions and fatigue damages that will eventually lead to structural failure, which is why it requires vibration control. The objective of this study is to investigate the possibilities application of using the piezoelectric diaphragm to control the vibration on a cantilever plate. A piezoelectric diaphragm is in this study because its lightweight; therefore, it is possible to add it to the structure without significantly changing the overall weight. A cantilever plate is consider to be used to analyse the vibration control where the cantilever plate is fixed at the root and free at the tip. In this study, only the first mode of vibration was considered because the most critical vibration happens during the first mode. The piezoelectric diaphragms are used as actuators that involve the active vibration control method at which this method essentially tries to eliminate vibration by adding the exact opposite vibration, resulting in cancelling overall amplitude. The effectiveness of vibration control has been investigated by placing the piezoelectric diaphragms at three different locations on the cantilever plate. Regarding the result obtained, the best vibration reduction of the cantilever plate is when the piezoelectric diaphragm was placed nearest the fixed end support with the percentage of vibration reduction of 46.42% zulaihi UTM 87 p.
