“…A force angle of 0°was used to obtain maximum shear stress in the shear pin in the shear stress calculations. On the basis of the guide vane torque results from the static operating load case, we calculated the shear stress in the shear pins using equation (6). The calculation results are plotted in Figure 8.…”

A design for the fail-safe mechanism of a guide vane in a Francis-type hydro turbine is proposed and analyzed. The mechanism that is based on a shear pin as a sacrificial component was designed to remain simple. Unlike the requirements of conventional designs, a shear pin must be able to withstand static and dynamic loads but must fail under a certain overload that could damage a guide vane. An accurate load determination and selection of the shear pin material were demonstrated. The static load for various opening angles of the guide vane were calculated using the computational fluid dynamics Fluent and finite element method Ansys programs. Furthermore, simulations for overload and dynamic load due to the waterhammer phenomenon were also conducted. The results of load calculations were used to select an appropriate shear pin material. Quasi-static shear tests were performed for two shear pins of aluminum alloy Al2024 subjected to different aging treatments (i.e. artificial and natural aging). The test results indicated that the Al2024 treated by natural aging is an appropriate material for a shear pin designed to function as a fail-safe mechanism for the guide vanes of a Francis-type hydro turbine.

Wind power is an affordable, efficient, and abundant source of electricity. It is pollution‐free and cost‐competitive with energy from new coal‐ and gas‐fired power plants in many regions. The wind industry has been growing rapidly in recent years. The rapid development of wind power industry requires higher performance and reliability of equipment. Thus, safety problem is extremely important to large scale wind turbines, as make safety engineering become the focus of WTs R&D. Thus, relevant researches have gained increasing attention in the wind industry. Accordingly, this article reviews the basic analysis types and their corresponding applications in WTs system safety analysis, aiming to let more experts deeply understand the current research status and also provide some guidance for relevant researches. © 2016 American Institute of Chemical Engineers Environ Prog, 35: 1848–1861, 2016
