中文摘要:
      针对环形和球形惯性稳定平台框架的不足,提出一种球面网壳型惯性稳定平台框架设计。组合正12面体和正20面体并映射到球面上,接着一次细化得到一种由240个弧三角构成的球面网壳。然后通过PROE绘制网壳,确定框架及各部件的大小,并处理轴安装部位,得到一种对流和导热效果很好且等刚度的球面网壳型惯性稳定平台框架。最后通过ANSYS软件作静力学仿真与模态分析,验证结构具有足够的刚度与强度。
English Summary:
      Considering the defaults of annular and spherical initial stable platform frames, the concept of spherical net shell style initial stable platform frame was put forward. The design firstly combined a pentagonal dodecahedron and a regular icosahedron in a symmetrical way, and then reflected the combinant onto a spherical surface. After that, the structure was subdivided into a kind of spherical net shell with 240 bow triangles. Meanwhile, the final net shell was generated via PROE, the size of the frame and its components was chosen, and the positions of axles installation were carefully modified. Finally we got a spherical net shell style initial stable platform frame with merits of good convection, perfect heat conduction and equal stiffness. Moreover, static structure analysis and modal analysis of the structure were carried out via ANSYS, proving its wonderful stiffness and strength
