摘要/Abstract

摘要： 为实现车辆柴油机缸套动载荷磨损的数值仿真计算，基于大修柴油机缸套表面形貌分析，确定并提出了缸套动载荷磨损的模式与简化机理；结合Archard黏着磨损模型和二体磨粒磨损模型，推导了动载荷磨损深度的一般表达式；利用缸套试件磨损试验数据，采用响应面拟合法建立磨损系数中的参数与载荷参数的数值关系，并通过两组缸套动载荷磨损试验对磨损计算模型进行了验证。实测与计算结果对比表明，磨损质量最大计算误差为6.15%，模型具有可靠的精度。

Abstract: In order to realize the numerical simulation on wear of diesel engine cylinder liner under dynamic load, the model and simplified mechanism of dynamic wear of cylinder liner are determined and presented based on the analysis of surface morphology of cylinder liner in overhaul diesel engine. A common expression of wearing depth is derived based on Archard adhesive wear model and two-body abrasive wear model. The response surface model is used to establish the numerical relationship between wear coefficient and dynamic load by analyzing the wear experimental data. The wear calculation model is verified by two groups of wear experiments under alternate loads. The test calculated results show that the maximum calculation error of wear mass is 6.15%, and the proposed model has reliable accuracy. Key
