为解决乏燃料后处理立式剪切机送料系统过程中易发生的未经剪切元件调入溶解器等故障问题,根据复杂工作条件(环境恶劣、负载重、放射性)下系统工作要求,提出一种卧式送料剪切机的翻转机构方案,使得乏燃料组件由立式转为卧式进行卧式激光切割。基于系统可靠度预设值,利用模糊综合评价方法对乏燃料后处理卧式送料翻转机构进行可靠度分配;根据翻转机构的工作原理创建串联系统可靠性模型;并对翻转机构的关键零部件进行可靠性设计,以活塞杆为例进行有限元仿真得知在满足系统功能要求及合理性的情况下,可靠性设计法得到零件的结构尺寸和重量明显减小,从而能避免冗余和减少材料成本。

In order to solve the problem of the failure of the non-shear element which transferred into the dissolver and so on,it is proposed to solve the problem of the system under the complicated working conditions such as bad,heavy load,and radioactiveenvironment.The spent fuel assembly is capable of being turned from a vertical position to a horizontal position for laser cutting by a flip-flop mechanism for a horizontal feed shearing machine.Based on the system reliability preset value,the fuzzy comprehensive evaluation method is used to distribute the reliability of the spent fuel horizontal feed ...
