Flow-Induced Vibration Response of the Chenderoh Dam Bottom Outlet Section Due to the Effects of Water Spilling

Hydropower-type dam can generate an electricity to the surrounding areas during the release of water from the upstream to the downstream. However, in some cases, the flow-induced vibration during the water spilling might induced significant vibration effects to the dam structure. This is a common ph...

Azman, M.A. Zawawi, M.H. Radzi, M.R.M. Hydropower-type dam can generate an electricity to the surrounding areas during the release of water from the upstream to the downstream. However, in some cases, the flow-induced vibration during the water spilling might induced significant vibration effects to the dam structure. This is a common phenomenon that happened in any of dam structures during the operating condition. In this study, the flow-induced vibration response at the bottom outlet section of the real scale Malaysian Chenderoh Dam model is investigated using ANSYS software. The results of frequency domain response and operational deflection shapes (ODS) from the flow-induced vibration are compared with the natural frequencies and mode shapes of the bottom outlet section. From the study, the transient vibration responses induced from the flow of water occurred at the operating frequency of 23.14 Hz while the natural frequency of the bottom outlet section is located at 9 Hz of frequency. This indicates that for the normal case of water spilling at the bottom outlet section, there is no resonance phenomenon happened. However, this result is useful for the dam operation section in order to avoid any disaster of the dam structure in the future. © Published under licence by IOP Publishing Ltd. 2020-02-03T03:26:55Z 2020-02-03T03:26:55Z 2019-06 Conference Proceeding 10.1088/1757-899X/652/1/012052 en IOP Conference Series: Materials Science and Engineering
