摘要

本文介绍了一种模拟近地轨道航天器磁场环境的试验平台。它由一个位于亥姆霍兹笼内的球形空气轴承组成。球面空气轴承用于模拟轨道物体的微重力条件,而亥姆霍兹笼在其运动过程中产生类似于卫星周围的可控磁场。专门的计算机软件用于初步计算在既定轨道上的磁场。然后,磁场数据被转换成电流值,并传输到可编程电源,为笼子供电。保持架内的磁场最终由安装在空气轴承上的测试件测量。本文介绍了试验台和试验件的设计情况。通过实验测试,证明了整个系统的良好性能。

TEST BED FOR THE SIMULATION OF MAGNETIC FIELD MEASUREMENTS OF LOW EARTH ORBIT SATELLITES
The paper presents a test bed designed to simulate magnetic environment experienced by a spacecraft on low Earth orbit. It consists of a spherical air bearing located inside a Helmholtz cage. The spherical air bearing is used for simulating microgravity conditions of orbiting bodies while the Helmholtz cage generates a controllable magnetic field resembling the one surrounding a satellite during its motion. Dedicated computer software is used to initially calculate the magnetic field on an established orbit. The magnetic field data is then translated into current values and transmitted to programmable power supplies energizing the cage. The magnetic field within the cage is finally measured by a test article mounted on the air bearing. The paper provides a description of the test bed and the test article design. An experimental test proves the good performance of the entire system.
