摘　　要：靶站地下室铅罐转运车(Lead Tank Transfer Vehicle, LTTV)是靶站地下室重要的转运设备,其运行环境及转运对象决定了其具有超高功率密度的特点。提出了一种新的车架构型,作为整车重量承载的基础及负重的支撑,新构型车架的设计分析尤为重要。根据整车的受力情况,基于材料力学理论进行应力与变形计算,结合有限元软件进行静力学分析,并对完成制造的车架样机进行了载重分析实验。分析、计算及实验结果表明,该构型车架设计满足许用应力指标。有限元分析较好地与理论计算结果相吻合,提高了设计效率并且为日后的优化升级提供了依据。Lead tank transfer vehicle is one of the most important transferring equipments in target station of China Spallation Neutron Source(CSNS), its operating environment and transport objects determine the characteristics of its ultra-high power density loading capacity. As the basis of the vehicle weight and load carrying support, the frame design is particularly important. According to the force condition of smoothly driving at low speed, complete the calculation of the stress and its deformation based on the theory of mechanics of materials, combine with the finite element analysis, and the loading tests. The results manifest that the maximum stress of the frame is less than the allowable one to meet the design specifications. The finite element analysis is in good coordination with the theoretical calculation results, which improves design efficiency and provides a reference for future optimization and upgrading.
