摘要
滚动轴承是机械系统中极易破坏的重要零件,它直接影响机械设备健康质量状况。首先,综述国内外轴承寿命研究的发展趋势和关键问题和滚动轴承疲劳寿命基本理论、寿命计算方法及寿命理论适应性的优劣;然后,概述断裂力学和损伤力学轴承寿命分析研究模型;最后,对损伤力学和断裂力学联合有限元分析进行分析展望,并考虑轴承游隙、变形量、内圈圆度误差对疲劳寿命的影响,提出一种试验与理论相结合、基于力学改进的轴承疲劳寿命分析新思路,希望能对提高轴承疲劳寿命分析预测精度有所借鉴。
Rolling bearing is an important part in mechanical systems,and it can directly affect the health and quality of mechanical equipment.First,it summarizes the development trends and key issues of bearing life research at home and abroad.Secondly,it summarizes the basic concepts of rolling bearing fatigue life,life calculation methods and the adaptability of life theory,then summarizes the fracture mechanics and damage mechanics analysis models of bearing life.Finally,this paper combines damage mechanics and fracture mechanics with finite element analysis,and considers the influence of bearing clearance and deformation and inner ring roundness error on fatigue life,a new idea of bearing fatigue life analysis based on improved mechanics in the combination of experiment and theory is proposed.It can improve the accuracy of bearing fatigue life analysis and prediction.This paper can provide reference directions for rolling bearing fatigue life analysis and prediction.
