A typhoon is a restrictive factor in the development of floating wind power in China. However, the influences of multistage typhoon wind and waves on offshore wind turbines have not yet been studied. Based on Typhoon Mangkhut, in this study, the characteristics of the motion response and structural loads of an offshore wind turbine are investigated during the travel process. For this purpose, a framework is established and verified for investigating the typhoon-induced effects of offshore wind turbines, including a multistage typhoon wave field and a coupled dynamic model of offshore wind turbines. On this basis, the motion response and structural loads of different stages are calculated and analyzed systematically. The results show that the maximum response does not exactly correspond to the maximum wave or wind stage. Considering only the maximum wave height or wind speed may underestimate the motion response during the traveling process of the typhoon, which has problems in guiding the anti-typhoon design of offshore wind turbines. In addition, the coupling motion between the floating foundation and turbine should be considered in the safety evaluation of the floating offshore wind turbine under typhoon conditions.

Stroke is a major problem in medical health, patients will have a lot of sequelae after cure. The purpose of this article is to review the results of previous articles and experiments on the comfort of different hand exoskeletons, aiming to improve the comfort of users. We analyzed the materials, wearing methods and binding methods of skin contact parts of various exoskeletons, and searched the corresponding keywords in Google Academic website to find the appropriate articles. Then the different ways of wearing exoskeletons were compared according to the test results. Then the comfort of each exoskeleton is concluded. The goal is to better explain and summarize the comfort of today's hand exoskeletons. Finally, the comfort characteristics of different methods are obtained according to several papers. Comfort is very important for patients, and the comfort of flexible exoskeletons is better than that of rigid exoskeletons.
