摘　　要：用于卫星姿态控制物理仿真试验平台必须要求有极小的摩擦阻力矩,而气浮轴承正好能满足于这种应用。本文根据皮卫星的物理仿真试验的需要,设计了单轴气浮台,该平台实测阻力矩达到5×10-5N.m,满足了设计要求。并对该气浮台的关键技术问题进行了探讨。The testing platform that applies to physical simulation testing for satellite attitude control requires an extremely small frictional resistance moment. However, the aerostatic bearing can just meet this challenge. A single - shaft air - floating platform was designed for a Picosat＇s physical simulation. The measured frictional resistance moment of the platform is 5 × 10^-5 N. m which meets the specification. The key technical problem on air- floating platform was discussed.
