用于谐波减速器性能试验的空间真空高低温环境模拟试验装置

谐波减速器作为重要的空间活动部件，其综合性能直接影响整个传动系统的运行状态。为掌握谐波减速器在空间环境下的服役性能，研制出一种谐波减速器空间环境模拟试验装置，主要用于空间真空高低温环境下谐波减速器的综合性能试验。通过将谐波减速器测试台架整体置于真空高低温试验舱内，避免使用磁流体密封轴，缩短传动链，从而降低试验装置累积误差。同时研制一套谐波减速器测试台架温度保护和监控系统，使测试台架能承受的空间环境温度范围达到-70～150 ℃。测试试验结果表明，该试验装置满足设计要求，可为空间传动机构传动性能评估、工作寿命及可靠性试验以及装置研制提供条件保障。

Space thermal vacuum simulation facility for performance test of harmonic reducer

The harmonic reducer is one of the important space moving parts, and its operation state directly affects the performance of the whole transmission system. In order to study the service performance of the harmonic reducer in the space environment, a specified simulation test facility is developed to be used for the comprehensive performance testing of the harmonic reducer in vacuum and high-low temperature environments. To reduce the transmission error of the test device system itself, the test bench of the harmonic reducer is placed in the facility chamber, to avoid the use of the magnetic fluid seal shaft and, meanwhile, to shorten the transmission chain. At the same time, a set of temperature control and monitoring systems for the harmonic reducer test bench is outfitted, to withstand the space environmental temperature of -70 ℃ to 150 ℃. The experimental results show that the test facility can meet the design requirements, and provide support for investigating the transmission performance, as well as the working life and reliability test of the spatial transmission mechanisms, and also for the development of such kind of devices.
