Through combining characteristics of the Direct Drive Wind Turbine's support shaft with finite element method and engineering method, this paper analyzes the support shaft finite element of static and modal fatigue life. Through the static analysis of the support shaft, the deformation and stress-strain results show that the maximum stress is lower than the allowable stress, and the support shaft meets the static strength safety requirements; through fatigue life analysis, the maximum fatigue stress is lower than the theoretical fatigue limit and meets the fatigue strength requirements of the support shaft. The results provide a theoretical basis of improvement of the design and program finalization.","PeriodicalId":6427,"journal":{"name":"2013 International Conference on Materials for Renewable Energy and Environment","volume":"31 1","pages":"382-385"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81923599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some aspects of design and operation are described in the paper. Natural gas, oil and water are simultaneously contained in the raw petroleum, which need to be heated up to 55°C-60°C in summer and to 68°C in winter. In order to make the system reliable, heat-pipe evacuated tube solar collectors have been used for the solar heating system. Totally 245 sets of heat-pipe evacuated tube collectors, including 1,960 tubes with total aperture area of 392 m2 are adopted. Practical operation results have shown that about 30% of daily average natural gas consumption could be saved.","PeriodicalId":6427,"journal":{"name":"2013 International Conference on Materials for Renewable Energy and Environment","volume":"35 1","pages":"155-158"},"PeriodicalIF":0.0,"publicationDate":"2013-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79720278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
