用于岩石冲击实验的试样加热装置
摘要：
本发明提供一种用于岩石冲击实验的试样加热装置，可用于岩石SHB(Split Hopkinson Bar)和动静组合加载等岩石冲击实验，属于岩石力学研究领域。装置包括调节滑道(9)，定位螺柱(10)，电阻丝(11)，找平螺栓(12)，支架(13)，电源开关(14)，可调保温仓门(15)，热电耦出入孔(16)，加热腔(17)，碳纤维增强合金筒(18)和保温仓(19)。本发明通过使用耐冲击、耐高温的碳纤维增强合金筒、可调保温仓门和装置底座的四个调平螺栓，实现岩石冲击实验过程中试样的持续恒定高温和冲击应力波加载的同步进行，为深部岩石力学研究提供了一种独特的实验装置。
摘要（英）：

The invention provides a sample heating apparatus used for a rock impact experiments as rock SHB and combined static-dynamic load and the like. and belongs to the rock mechanics study field. The apparatus comprises an adjusting slideway (9), a locating bolt (10), a resistance wire (11), leveling bolts (12), a bracket (13), a power-supply switch (14), an adjustable insulation bin-door (15), a thermocouple access hole (16), a heating cavity (17), a carbon-fiber reinforced alloy cylinder (18) and an insulation bin (19). The invention adopts the anti-impact and anti-high-temperature carbon-fiber reinforced alloy cylinder, the adjustable insulation bin-door and four leveling bolts at the seat of the apparatus to realize the synchronous processes of preserving the constant high temperature and the loading of impact stress wave during the rock impact experiment. The invention provides a special experimental apparatus for the further rock mechanics study.
