Though the satellite was originally designed to work for 3 years, it still operates steadily. As the nation's first operational first-generation geo- stationary meteorological satellite, FY-2C works together with the following satellites FY-2D, FY-2E and FY-2F, in a operational mode of two operational plus two backup ones. FY-2C, FY-2D and FY-2E were the second batch satellites of FY-2 series展开更多

It not only needs to meet the current functional requirements of the current use of prefabricated buildings, but also to ensure the rationality and safety of the structure while taking into account the economic, social, environmental and other benefits. Effectively carrying out the structural design and management of prefabricated buildings can strengthen the quality of prefabricated buildings from many aspects and also promote the healthy development of the prefabricated building industry.展开更多

Only by strengthening the research and application of BIM technology, can the construction units better ensure the design accuracy of the building structure, so as to promote the overall improvement of the construction engineering efficiency and its degree of refinement. Therefore, the BIM technology should be actively applied in the architectural deepening design to fully improve the overall efficiency of the deepening design.展开更多

The measures include the fol- lowing five aspects : optimally selecting the material and heat treatment process , optimally designing the tooth profile . reasonably choosing the manufacture accuracy and technique , optimally choosing the lubricant and the way of lubrication and seal , improving the dynamic feature of the gearing. In the respect of the tooth profile , a hob with optimal cutter angles is designed to make root thickness on the dangerous section as large as possible and the stress concentration as small as possible. Ad- dendum modification coefficient is optimized to minimize the maximum flash temperature in the course of meshing. Finally . finite element analysis method is used to calculate the deformation and the stress of teeth accurately. And on this basis , optimal profile correction and axial modification have been designed with regard to the start , continuious running and high speed travel of the loco- motive .展开更多
