摘要

摘要: 基于临界平面法,提出一种多轴疲劳损伤参量和多轴寿命预测模型,与传统损伤参量以最大剪应变变程平面为临界平面不同,该损伤参量以最大损伤平面为临界平面,考虑最大剪应变变程,作用在最大剪应变变程平面上的法向应变变程和最大法向应力对疲劳裂纹萌生与扩展的综合作用,更好地反映非比例加载产生的循环附加强化导致疲劳寿命减小的现象,并且该损伤参量不含经验常数,不需进行平均应力修正,适于工程应用.经3种材料试样多轴疲劳试验验证,该模型预测结果较好.使用该损伤参量对某型发动机涡轮盘传动臂销钉孔寿命进行预测进一步证明以最大损伤平面为临界平面的损伤参量的工程适用性.

Abstract: Based on the critical plane method,a multiaxial damage parameter and a life prediction model were proposed.Differ from the traditional damage parameter whith takes the maximum shear strain range as the critical plane,this damage parameter,taking the maximum damage plane as the critical plane,integrates the maximum shear range with the normal strain range and the maximum normal stress on the maximum shear range plane and reflects the reduction fatigue life owing to the additional cyclic hardening with the non-proportional loading.It is convenient for engineering application because there is no material constants in this parameter and no need to consider the mean stress.Experimental verifications show that the proposed parameter gives better satisfactory results for three checked metals under proportional and non-proportional loading.The life prediction result of a turbine disk transmission arm pin hole using this parameter further proves the engineering applicability of taking the maximum damage plane as the critical plane.
