【摘要】 双密封门系统是国际热核实验堆(ITER,International Thermonuclear Experimental Reactor)遥控部件转运车上的一个重要系统,在部件转运车工作过程中能防止核污染物和有毒尘埃的外泄。双密封门的打开和关闭是一个复杂的操作过程,它的运动方向和液压杆受力在导轨拐点处将发生明显改变,因此在双密封门导轨拐点处很有可能发生结构损坏或系统失效。基于双密封门的特殊结构、限制条件和工作程序,应用ADAMS对双密封门系统进行建模并进行运动学分析,得到运动导轨和液压杆的受力分布,同时根据受力分析结果确定了双密封门导轨拐点位置。上述分析过程和结果不仅为双密封门的优化设计和实体模型的制造提供数字依据,而且为ITER其它重要部件的运动学分析提供范例和参考。更多还原

【Abstract】 Double seal door(DSD) system is an important part of ITER remote handling transfer cask system,prevents toxic substances exposure to outer circumstance when the cask is working.Its opening and closure is a complex operation,the moving direction of DSD and the force of hydraulic pole will change significantly at the guide rail inflexion position(GRIP), in where the structure may be damaged and the system maybe failure.The kinematics simulation and analysis of DSD were done based on special constitution restriction and working process by software ADAMS.The stress distribution of guide rail and hydraulic pole were obtained by the above simulation,at the same time the optimal GRIP was confirmed according to the force analysis result.The above-mentioned analysis process and results not only provide technical data for the optimization design and the prototype manufacture of DSD,but also provide the examples and references of kinematics analysis for other important components of ITER.更多还原
