摘　　要：大型空间展开机构在微重力环境工作,自身不具备克服地面重力展开的能力,在地面进行展开试验验证时,需对机构进行重力卸载。套筒驱动的大型可展收柔性太阳翼存在在轨展开步骤多路径复杂、活动部件多、收拢构型紧凑而展开尺度大的特点,地面重力卸载难以实现。以过程无需调整航天器姿态就完成全部展开步骤为目标,利用气浮法、配重法、悬吊法等对展开过程的不同步骤设计了相应的重力卸载方案。采用特殊构型的工装解决了干涉问题,采用主动牵引的方法消除了工装引入的摩擦力。方案得到地面展开试验验证,具有工程借鉴价值。The large space deployable mechanism working in microgravity environment cannot work under the ground gravity,so it is quite necessary to compensate the gravity of the mechanism during the ground test.The ground gravity compensation for the large deployable flexible solar array driven by telescopic boom is difficult to realize due to the characteristics such as the multiple steps in de-ployment,the complex path,the many moving parts,the compact configuration and the large expan-sion scale.To complete all the deployment steps without spacecraft attitude adjustment,the air flota-tion method,the counterweight method and the suspension method were adopted to design the corre-sponding gravity compensation scheme for each step of the deployment process.The interference problem was solved by using a special configuration device,and the frictional force of the device was counteracted by active traction.The scheme was verified by ground test and may serve as a good ref-erence for the engineering application.
