凸轮轴磨损再制造疲劳寿命分析
Fatigue life analysis of camshaft wear remanufacturing
摘要
Abstract
In order to evaluate the possibility of remanufacturing and repairing of engine camshaft under different wear conditions,taking the camshaft of Jichai 12V190 diesel engine as the research object,the camshaft models of three states of non-wear,local deep wear of 4 mm and overall shallow wear of 3%were established by finite element method.Based on ANSYS Workbench software,the transient stress analysis was carried out to explore the influence of wear on the surface stress field of camshaft.And combined with nCode DesignLife software for the fatigue life prediction.The results show that the fatigue life of the camshafts with two different degrees of wear is not less than 1.8×104 hours,which meets the minimum service life standard required for remanufacturing.At the same time,it is revealed that wear will weaken the fatigue performance of the camshaft,and the local deep wear of 4 mm has a more prominent effect on the reduction of life than the overall shallow wear of 3%.The research results confirm the potential of camshaft remanufacturing under specific wear conditions,and provide valuable references for the optimal design of related remanufacturing processes.关键词
