摘　　要：文章介绍了一种空间遥感相机自由度释放装置,该装置利用柔性铰链技术实现单方向的自由度释放,同时结合固定脚的设置和不同方向柔性铰链的设置,实现多维自由度卸载的同时保证结构整体的刚度。结合某型号空间遥感相机对该装置进行了力学振动试验和热真空、热循环试验,验证了该装置的可行性。This article introduces a kind of releasing mechanism of motion freedom of space remote sensing camera. The installation makes use of the technology of flexible hinge joint to realize the release of multi-directional motion freedom, and combines the setting of the fixed end and the setting of diverse directional flexible hinge joint to realize unloading of multidimensional motion freedom and keep the stiffness of the construction at the same time. In addition, combining with a certain space remote sensing camera, we carry out mechanic vibration test, thermal vacuum test and thermal cycling test and verify the feasibility of the installation.
