Abstract: In order to generate electricity by converting wave energy into mechanical energy, a buoy-type wave energy generating device is designed, it includes overall design, reversing gearbox design and buoy design. The test stand of wave simulation is set up and the rationality of generating device is verified by generating experiment.

Abstract: In order to investigate the life of bearings lubricated by solid lubricant (BLSL), which are installed in the rotational parts of spacecraft, a test platform has been developed. The platform can test the life of BLSL working under the vacuum environment with high-low temperature cycle conditions. The test platform consists of three systems of loading, measurement, and power and speed control. A corresponding computer program was also developed to measure, monitor and record test data. The working life of deep groove ball bearings lubricated by MoS₂ solid lubricant was tested in 5×10^-4Pa vacuum. The surface observation and analysis for the damage condition of the failed bearings were also conducted.
