水轮机流固耦合振动研究的发展趋势

Some perspective the studies on hydraulic-turbine by fluid-solid coupling

现代社会水轮机尺寸和容量越来越大，刚性降低，稳定性运行日益重要。随着计算机技术和计算力学的发展，机组的稳定性研究出现了新的特点。本文对此进行了分析回顾，重点介绍了流固耦合的研究现状。最后，对我国水力机组振动特性的研究提出了一些建议。

The dimension and capacity of hydraulic-turbines in the modern world become more and more big, but the rigidity reduces, so the stability of hydraulic-turbines is of emphasis. The new research methods for vibration of hydraulic-turbines set were come forth along with the development of computer technology and CFD. Review was analyzed in this paper in particular introduced the research status of fluid-solid coupling. Finally, some advice as to the vibration investigation for hydraulic-turbines set in our country was put forward.
