摘　　要：针对重型车辆柴油机缸套磨损在实际使用过程中检测难度大、测量过程复杂的问题,基于柴油机缸套磨损的仿真计算,依据Archard黏着磨损模型、二体磨粒磨损模型以及表面粗糙度变化规律,设计了一种适用于实车不拆解检测的缸套磨损快速计算模型,并进行了实车验证。结果表明:表面粗糙度计算误差为7.1%,缸套磨损深度计算误差为10.4%,模型误差较为合理,可以应用于实车计算。Aiming at the problem that the wear of cylinder liners on heavy diesel engine is difficult and complex to measure,on the basis of Archard model of adhesive wear,double-body model of wear,the change rule of the surface roughness and the simulation of diesel engine cylinder liner and piston ring,an applicable fast calculation model of cylinder liner wear is designed and tested on the vehicle.The results indicate that the calculation error of the surface roughness is 7 .1%,the calculation error of cylinder liner wear depth is 10.4%,the accuracy of the model is acceptable,which can be applied to a practical cal-culation.
