Linear-Impact Behaviour of PWR Fuel Assembly
시간적분법을 이용한 경수로 핵연료집합체의 선형충격 거동해석
Abstract
A finite element model for the transient dynamic analysis of a PWR fuel assembly was developed and programmed as a name of DAMASS. The Newmark time integration method was used to solve the governing equation of motion. Results of the program was compared with those of ANSYS in terms of displacement and impact forces to show the validity of the model. Up to now it has capability of solving the linear impact of FA(s) and it will be extended to the non-linear analysis of a FA in the future.
