摘　　要：针对二维展开太阳翼地面展开过程中重力卸载较困难的情况,设计了适用于二维展开太阳翼的地面展开重力卸载装置,建立了某二维太阳翼在此地面展开试验装置上的动力学模型并进行了动力学仿真分析,分析结果表明太阳翼能够正常展开并锁定,除了太阳翼一次和二次锁定前后瞬间,其余展开过程中吊挂绳索张力最大变化量仅为7%,展开后最大变化不超过2%;该试验装置在某太阳翼上的应用结果表明太阳翼展开前后吊挂绳索吊挂力变化不超过1N。此试验装置可为其他空间二维展开机构的地面展开试验提供参考。To solve the gravity offloading difficulty of 2-dimensional solar array on ground deployment test,a deployment test rig is designed in this paper.The dynamic model of a 2-dimensional solar array on the test rig is built and the dynamic simulation is performed.The simulation results show that the solar array deploys and locks normally,demonstrating that the deployment test rig is effective for the gravity offloading of 2-dimensional solar array.Except the short time before and after the first and the second locking of the solar array,the maximum deviation of the force in the suspension rope is only 7%in the solar array deployment process and less than 2%when finished.The test results of a 2-dimensional solar array on this test rig show the rope suspension force before and after deployment changes no more than 1N.This test rig can be referred by other 2-dimensional space mechanisms ground deployment test.
