摘　　要：在薄壁缸套表面的微坑结构参数影响分析基础上,确定了影响动力润滑的设计变量,以瞬时最小油膜厚度最大化和润滑油损耗量最少为优化目标,建立了优化模型。将竞选算法用于缸套微坑结构参数优化求解,很快地获得全局优化解,结果表明该方法是可行的。Based on the lubrication dynamic analysis of micro-pit cylinder sleeve, the design parameters concerning dynamic lubrication were determined, maximizing the least lubricating film thickness and minimizing lubricant wastage are appointed as optimization object, and the optimization model was established. Election-survey algorithm was used to search the optimization solutions of parameter of micro-pit cylinder sleeve, the optimization solutions were found out rapidly, it is shown that this method is feasible.
