Abstract: The bolts of cover system are ruptures when cover system effected by transient load. According to the experiment data and research result to find, the frequency of loads is similar to cover system, and result in resonance. In order to eliminating resonance, change the original cover system frequency by adding damper. This paper adopts additional water mass method for wet modal; conclude inherent frequency and mode of vibration. Using FEM simulation on the two cases, to assess the effect of reduce load.
