【摘要】 本文在4．19×104＜Re＜5．21×105，1．96≤Kc≤7．85，0．42≤Vr＜5．01的范围内，实验研究了孤立圆柱在均匀流场、波浪及浪流中的动态响应。研究表明在三种流场中，往在横向以涡激振动为主；在流向，三者之间存在着较大的差异，且在浪流中，波浪对柱的撞击作用不能忽视。更多还原

【Abstract】 The dynamic response of an isolate cylinder in uniform flow field,in waves and under combined action of waves and current respectivaly is investigated experimentally in the range of 4. 19 ×104 ＜Re＜5. 21×105, 1. 96≤Kc≤7. 85, 0. 42≤Vr≤5.1. The test results show that the cylinder vibration in the lateral direction is mainly excited by vortex of the above mentioned three kinds of flow fields,while the cylinder vibrations in the flow directioon have obvious differences among these flow fields. Furthermore, the impact ation on the cylinder due to the waves can not be ignord.更多还原
