Illuminated the principle of transient thermal transfer analysis. Accomplished the transient thermal analysis based on the model of ellipsoidal dome  and studied the influence about the different material and the different velocity. Considered three materials consist of MgF2  Al2O3  and ZnS  and meanwhile  the velocity was Mach2.5  and the time consists of 10s  20s and 60s. The temperature initial loads were from FLUENT thermal simulation. The thermal conduction analysis and the thermal convection analysis were finished in software ANSYS  in which the entire transient thermal analysis consists of modeling  meshing element  calculating and getting the results. The different temperature distributions based on varied time were gotten about the different materials. The results from analysis showed the temperature distribution of the structure of ellipsoidal dome  which could help the following coupled thermal-structure analysis. 2011 IEEE.   Thermal-structure analysis of supersonic dome based on three materials (EI CONFERENCE) 会议论文 2011 International Conference on Electric Information and Control Engineering, ICEICE 2011, April 15, 2011 - April 17, 2011, Wuhan, China Jiang Z.; Ai X.; Wei Q.; Liu B.; Jia H. 收藏  |  浏览/下载：17/0  |  提交时间：2013/03/25 To a supersonic missile  a seeker could enhance the aerodynamic ability due to decrease the resistance in flying. 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.   Dome design and coupled thermal-mechanical analysis of supersonic missile (EI CONFERENCE) 会议论文 2009 International Conference on Optical Instruments and Technology, OIT 2009, October 19, 2009 - October 22, 2009, Shanghai, China Xing-qiao A.; Qun W.; Hong-guang J. 收藏  |  浏览/下载：40/0  |  提交时间：2013/03/25 A review of high-speed flow pressure and aerodynamic heating effect on Supersonic missile's dome is given. The dome should have excellent properties in optical  mechanical and chemical characteristics. A design of dome on supersonic mode is described according to tactical guide line of a missile. The dome made of quartz which is about 8mm thick and 141mm in window diameter. To check up the reliability of the dome  a reasonable finite element model (FEM) of dome is established  and a thermal-mechanical Analysis to the dome by finite element software NASTRAN has carried on  through these can obtained the distribution of temperature field and stress field when the speed is 2.3Ma. The results indicated that the stress was concentrated in the joint of the dome end and the Missile Section  and the maximum stress was 16.4Mpa. The stress of other nodes was smaller than the allowable stress of quartz glass. Reference to the results of the analysis  a lightweight revision to the dome structural dimension and a new method of dome fixing have put forward  which can reduce the stress concentration. 2009 SPIE.
