To study the equivalence of three-dimensional on-orbit dynamic characteristics and two-dimensional ground test, the dynamic relationship between the ground and on-orbit test system was established by the second Lagrange dynamic method, and the matching of mass characteristics was designed. Based on the designed mass characteristics, two kinds of simulation analysis including the on-orbit translocation and ground test were carried out. The simulation results showed that the on-or-bit and ground dynamics were in good agreement both in trend and peak value. The mass character-istics of the experimental cabin simulator could be used for the development the ground test system.%针对空间站舱体转位地面试验二维模拟空间三维动力学特性的等效性问题,通过第二类拉格朗日动力学方法,建立起在轨与地面试验系统之间的动力学关系,进行了质量特性匹配性设计.基于设计的质量特性,进行了在轨转位和地面试验转位两种仿真分析,仿真结果表明,在轨与地面动力学仿真结果在趋势和峰值两方面一致性很好,所设计的实验舱模拟器质量特性可以用于地面试验系统的研制.
