辐射计效应和气体阻尼是纯引力轨道验证质量的重要干扰力,是影响纯引力轨道构造水平的重要因素。在纯引力轨道飞行器中,这两种力分别描述了由腔体中温度梯度和验证质量相对运动引起的气体分子作用,两者从不同角度描述了气体分子作用力,均是气体分子作用力的一部分,而两者的耦合模型则可以反映验证质量受到的气体分子作用力总和。针对耦合模型形式复杂的特点,本文以内编队系统为例,利用数值方法分析了耦合模型中的影响因素,这些因素包括内卫星相对运动速度、内卫星半径、外卫星腔体半径、腔体平均温度、腔体温差和腔体平均压力等。对大量计算结果进行了数据拟合,给出了内卫星气体分子作用力与各物理参数关系的拟合公式,和原始计算结果相比,拟合误差在20%以内。
Radiometer effect and gas damping are important disturbing forces of the pure gravitation orbit verification quality and are important factors affecting the level of pure gravitational orbit structure. In a pure gravitational orbiter, these two forces describe the gas molecular action caused by the temperature gradient in the cavity and the relative mass of the proof mass, respectively, describing the gas molecular forces from different angles, all of which are gas molecular forces Part of the coupling model of the two can reflect the quality of the gas molecules subjected to verification. Considering the complex form of the coupled model, this paper takes the internal formation system as an example to analyze the influencing factors in the coupled model by using numerical methods. These factors include the relative moving velocity of the internal satellite, the radius of the internal satellite, the radius of the external satellite cavity, the average cavity temperature , Cavity temperature difference and cavity average pressure. A large number of calculation results were fitted to the data, and the fitting formula of the relationship between the molecular force of inner satellite gas and each physical parameter was given. Compared with the original calculation result, the fitting error was within 20%.
