Vibration Analysis of the Research Vessel"Zhang Qian"
摘要
Abstract
The vibration performance of the scientific research vessel"Zhang Qian"was analyzed. First of all, the specific methods for analyzing the whole vessel were introduced. The model of the vessel was built via the 3-dimensional modeling software based on the drawings of the vessel. Secondly, additional water mass was added to the ship hall and different loads were added to the deck to simulate the working conditions of full-load and load-free. Then, the modal frequencies and mode shapes under different conditions were computed. Thirdly, a flow field model was built surrounding the ship and furthermore a fluid-solid coupling model was established to simulate the ship’s free-floating condition over the water. Finally, input excitations of different devices on the deck of the ship under the working conditions were constructed and the local vibration of the ship was computed.关键词
