摘要

通过优化磨合参数（负荷、速度和磨合时间），可以提高磨合质量。分析了磨合质量与摩擦信号和磨损表面分形维数之间的关系。结果表明，分形维数越大，磨合质量越好。采用精英策略的非支配排序遗传算法，对主轴承磨合参数进行了多目标优化设计。优化目标是摩擦系数的大分维、磨损表面的大分维数和小磨合时间。结果表明，不同阶段、不同优先级的磨合参数选择原则不同。本文所列的最佳磨合参数，为主轴承三级磨合的优化设计提供了具体参考。

Multi-objective optimization of three-stage running-in process for main bearing of marine diesel engine

Running-in quality can be improved by optimizing the running-in parameters (load, speed and running-in time). The relationship between running-in quality and the fractal dimensions of friction signal and wear surface is analyzed. It shows that the larger the fractal dimension, the better the running-in quality. A multi-objective optimization design of the running-in parameters of the main bearing is carried out, using a non-dominated sorting genetic algorithm with elite strategy. The optimization targets are the large fractal dimension of friction coefficient, the large fractal dimension of wear surface, and small running-in time. It shows that the selection principles of running-in parameters are different for different stages and priorities. The optimal running-in parameters listed in this paper provides a specific reference to the optimal design of the three-stage running in of main bearing.
