	Engineering analysis and research on connection plate of vehicle radar antenna pedestal (EI CONFERENCE) 会议论文 OAI收割 3rd International Conference on Frontiers of Manufacturing and Design Science, ICFMD 2012, December 11, 2012 - December 13, 2012, Hong kong 作者: Sun H.; Sun H.; Li Y.; Li Y.; Li Y. 收藏 \| 浏览/下载：26/0 \| 提交时间：2013/03/25 According to the usage of vehicle radar antenna pedestal connection plate this article analyzes and compares the structure characteristic of welding and casting. We decide to adopt the casting structure and use cast aluminium ZL101A. Based on the connection plate of using conditions we analyze the deformation and stress of connection plate by the finite element analysis software. The design is in line with the material allowable requirements and to meet the requirements of the system stiffness. (2013) Trans Tech Publications Switzerland.

	Brazing RB-SiC used in large aperture space optical system (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Materials and Products Manufacturing Technology, ICMPMT 2011, October 28, 2011 - October 30, 2011, Chengdu, China Zhang B.; Zhang Z. 收藏 \| 浏览/下载：24/0 \| 提交时间：2013/03/25 Because of the sic material's superior optical characteristic machine characteristic and hot characteristic it becomes currently the space big aperture reflector choose firstly1. For larger aperture sic mirror it is not economical and safe to make the monolithic body directly 2 3. The SiC mirror brazed assembly with several segments can solve these problems. In this paper one 600 mm sic plane mirror as demonstration welded with 3 radial segments is roughly grinded to the required figure at first then the mirror is finely grinded and polished by the technology of CCOS the mirror figure error is less than 1/20 ( = 632.8nm) in RMS finally. The problems of the preferential removal near braze joint are solved. The methods of reducing the residual stress of mirror are discussed. At last some measurements and experiments are carried on and the results conclude that the brazed SiC mirror can meet the requirement of large aperture optical systems.
