摘　　要：野外使用光学仪器其支撑结构需满足一定稳定条件。为了验证在野外用光轴一致性测试时光学仪器能否在几级风压情况下满足仪器光轴轴线偏角小于8秒,利用MSC.Patran&Nastran有限元分析软件对光学仪器支撑结构进行了抗风压有限元分析和优化。分析结果表明,在四级风压的情况下,光学仪器的偏角可以满足偏角小于8秒。The optical instrument should be satisfied the stability condition.In order to verify the technical index of de-flection of optical axial less than 8 seconds under which levele wind pressure of optical instrument on outer field when making multiaxis parallelism. In this paper, the supporting structure of optical instrument was analyzed and optimized with MSC.Patran＆amp;Nastran software. The results shown that the deflection of optical instrument can satisfy less than 8 seconds at 4 level wind pressure.
