摘要

摘要:
核动力厂燃料组件转运系统运行的平稳性和系统结构的可靠性对确保燃料组件安全至关重要。为了解运行过程中系统的振动情况，建立了考虑水影响的梁-小车+刚性杆-质量+弹簧+阻尼的耦合系统动力学模型，推导了系统的非线性运动微分方程。在此基础上，采用数值算法计算了小车在不同行走速度下系统的响应。研究结果表明：运行过程中，小车行走速度越小系统振动越弱，相对越平稳；由于静变形，即使小车行走速度很低，吊篮仍会承受一定的横向力作用，需注意吊篮薄弱部位的强度；导轨支撑附近位置为吊篮的相对危险位置，必要时可以在此设置监测点以保证燃料组件安全。

Abstract:
The stability of fuel assembly transfer system and the reliability of system structure are very important to ensure the safety of fuel assembly in nuclear power plant. In order to obtain the vibration of system during the running process, the dynamic model of coupling system of the beam-truck+link-mass+spring+damping was established. Considering the effect of water, the nonlinear differential equation of the system is derived. The response of the system under different traveling speeds of truck was calculated by numerical algorithm. After comparison and analysis, it is considered that the smaller the truck speed is, the weaker the system vibration is and the more stable it is; due to the static deformation, even when the speed is very low, the basket will still bear a certain lateral force, so it is necessary to pay attention to the strength of the weak part of the basket; the position near the guide rail support is the dangerous position for the basket, and monitoring points can be set here if necessary to ensure the safety of the fuel assembly.
