摘要
为建立涂层锆合金包壳微动磨损的有限元计算分析模型,预测切向工况下的最大磨损深度,基于包壳-格架的实际几何特征建立了涂层锆合金包壳-刚凸接触系统的有限元模型,采用Archard磨损模型计算磨损量,结合ABAQUS的ALE功能和UMESHMOTION子程序模拟磨损过程。根据微动磨损试验结果分析磨损系数随磨损周次的变化情况,并拟合其函数关系。有限元计算的最大磨损深度和最大深度的位置与试验结果相符,表明所建立的模型可用于涂层锆合金包壳切向微动磨损最大深度的预测。
To build a finite element calculation and analysis model of fretting wear of coated zirconium alloy cladding and predict the maximum wear depth under tangential working conditions,the finite element model of coated zirconium alloy cladding-dimple contact system is established based on the geometrical characteristics of cladding-lattice.The Archard wear model is employed to calculate the wear amount,and the wear process is achieved through the integration of ABAQUS ALE technology and the UMESHMOTION subroutine.The wear coefficient and its relationship with wear cycle are analyzed through fretting wear testing,and a fitted function is derived to describe the relationship.Our results obtained from the finite element analysis show the maximum wear depth and its corresponding position are in agreement with the test results.Our study demonstrates the established model may be employed to predict the maximum depth of tangential fretting wear on coated zirconium alloy cladding.
