In order to acquire the mechanical environment data in launching and on orbit section of a manned spacecraft, an orbital environment measurement system for the spacecraft is designed and tested in the vibration experiment, and the mechanical environmental data of the representative structure of the manned spacecraft is acquired and analyzed in the frequency domain. A comparison is made between the data of the measurement system and the data of the manned spacecraft in the vibration experiment. The result verifies the availability of the system. The research provides a reference for the formulation and revision of the orbit condition of the manned spacecraft.%为获取载人航天器上升段与在轨期间的力学环境,设计了在轨力学环境测量系统,并在载人航天器振动试验期间对其性能进行了测试,获取了航天器典型结构的力学环境数据并进行了频谱分析.将该系统测量数据与试验中载人航天器平台测点的测量数据进行了比对,结果验证了该系统的有效性,为载人航天器载荷条件的制修订提供了参考.
