During the period from October 2000 to November 2005, the canister in the CRT deposition hole DD0092G01 was heated with a maximum heat power of 2600W and the temperature and consequently the stress in the surrounding rock volume were elevated. This study investigated if the temperature and possible heat induced damage can be predicted by 2-Dimensional numerical simulations. FLAC2D(5.00) was used to model the excavation and the heating process of the deposition hole. Temperature in the rock was calculated by treating the case either as a horizontal two dimensional or a vertical axisymmetric problem and obtained results were compared with the measured results, whereas stress was calculated from horizontal two dimensional thermal-mechanical coupling analysis and calculated results were applied to approximate damage analysis.

According to the structure and its transmission principle of the cycloid ball planetary drive, a thermo-mechanical coupling analysis model of non-backlash cycloid ball engagement pair is developed in this paper. The force formula is derived by using hyperstatic method. Using finite element analysis, the variation of thermo-mechanical coupling contact stress of engagement pair at maximum force position with working temperature has been obtained. The results show that maximum coupling contact stress is located at the load transfer contact points between the ball and the cycloid grooves, and it increases significantly with the increase of temperature. The results obtained offer important theoretical basses for research on reliability of precision cycloid ball engagement pair and design of non-backlash transmission performance.
