Main structure of truss type optical remote sensing load cabin

The invention provides a main structure of a truss type optical remote sensing load cabin, the main structure has the functions of space avoidance and efficient bearing, and solves the problem of difficulty in satellite configuration and force transmission due to the fact that an ultra-large camera is embedded into a cabin body to form a 2m large opening. According to the invention, a novel load cabin configuration of 'box separation and pull rod' is designed, transverse load is transmitted between the two independent truss type box structures through the pull rod, and the space between the two box structures forms an avoiding area of a load part, so that the problems that the load part configuration is special and a large-range avoiding space is needed are solved. 本发明提供了一种桁架式光学遥感载荷舱主结构，能够兼具空间避让及高效承载，解决超大型相机嵌入舱体形成2m大开口，导致卫星构型和传力困难的难题。本发明设计了"分箱+拉杆"式新型载荷舱构型，两个独立的桁架式箱体结构中间通过拉杆传递横向载荷，两个箱体中间的空间形成了载荷部件的避让区域，解决了载荷部件构型特殊，需要大范围避让空间的难题。
