At the same time  the primary function of a seeker has been considered as the most important equipment for a missile  due to the importance for cueing of targets and tracking for the final approach. However  the dome of a seeker  which is made up of glass  has poor mechanical performance. Especially  in the higher altitude  for a dome  in which the aerothermal and pressure loads could destroy the structure easily  it is necessary to do the thermal-structure coupled analysis due to varied materials. In the paper  to take the spherical dome of a seeker as a example  the analysis has been completed according to the varied materials consist of MgF2  Al2O3 and ZnS. The temperature loads and the pressure loads derived from the results of fluent analysis has been forced on the surface of dome  which simulates the actual Mach 2.5 in flying. According to the results of coupled analysis  the SEQV stress of the dome radium 80mm based on three materials had reached to 31MPa  which shows that the strength is sufficient for Mach 2.5  and offered the warranty to design the attaching to missile for the dome. At the same time  the results required the flexible mounting for the dome due to the displacements results  which the crystal material couldn't accept. 2011 IEEE.   Analysis of the impact of cracking old portland cement concrete pavement to underground pipe 会议论文 Kunming, China, July 29, 2011 - July 31, 2011 作者:  Li, Ping;  He, Chen;  Wu, Guixian;  Wang, Xiuli 收藏  |  浏览/下载：6/0  |  提交时间：2020/11/15 Building materials  Civil engineering  Concrete construction  Construction equipment  Finite element method  Pipe  Portland cement  Three dimensional  Additional stress  ADINA  PCC pavement  Soil pressure  Underground pipes   Study on the reclaimed binder properties using vacuum rotating reclaim 会议论文 Guangzhou, China, January 7, 2011 - January 9, 2011 作者:  Jia, Liang;  Zhu, Yanpeng 收藏  |  浏览/下载：5/0  |  提交时间：2020/11/15 Asphalt  Asphalt pavements  Building materials  Concrete construction  Construction equipment  Creep  Ductility  Elastic moduli  Human engineering  Recycling  Rotation  Stiffness  Trichloroethylene  Vacuum  Vacuum technology  Viscosity  Aging degree  Asphalt concrete pavements  Asphalt concretes  Bending creep  Binder properties  Comparison result  Dynamic shear modulus  Human factors  Performance indices  Performance of asphalt  Petroleum asphalt  Phase angles  Pressure aging vessel  Recycled asphalt  Softening points   Finite element analysis of the formation mechanism of electrode pitting in resistance spot welding of an aluminum alloy 期刊论文 2010, 2010 Baohua Chang; Dong Du; Zhou, Y. 收藏  |  浏览/下载：9/0 Test and analysis of noise reduction effect for different heights and distances of sound barrier (EI收录) 会议论文 Advanced Materials Research, Haikou, China, June 18, 2011 - June 20, 2011 作者:  Liu, Yan[1,2];  Yang, Bing[2,3];  Zhang, Xiaopai[1];  Zhong, Zhifang[1];  Dong, Huaxin[1] 收藏  |  浏览/下载：1/0  |  提交时间：2019/04/15 Acoustic noise measurement  Acoustic wave transmission  Building materials  Civil engineering  Construction equipment  Frequency bands  Noise pollution  Pressure effects  Roads and streets  Spectroscopy  Spectrum analysis  Testing  Ultrasonics  Vibration analysis   Die wall lubricated warm compaction of Fe-Ni-Cu-Mo-C powders (EI收录) 会议论文 Advanced Materials Research, Guangzhou, China, January 7, 2011 - January 9, 2011 作者:  Ke, Meiyuan[1];  Xiao, Zhiyu[2] 收藏  |  浏览/下载：1/0  |  提交时间：2019/04/15 Algebra  Building materials  Construction equipment  Dies  Lubrication  Metallurgy  Powders  Pressure effects  Sintering  Walls (structural partitions)
