虽然我国保持汽车第一产销大国之位,但是我国汽车生产和制造过程中存在许多问题,特别是在发动机技术研发方面,和国外发达国家还存在很大的差距。因此,为了提高发动机的性能,就必须提高发动机制造的精密度,文章基于微分进化理论,探析了公差反推设计在发动机精密制造中的应用,以供参考。
Although China keeps the number one big country in the production and sales of automobiles, there are still many problems in the process of automobile production and manufacturing in our country. In particular, there is still a long way to go in terms of engine technology research and development with other developed countries. Therefore, in order to improve the performance of the engine, it is necessary to improve the precision of the engine manufacturing. Based on the differential evolution theory, the article explores the application of the tolerance-based backstepping design in the engine precision manufacturing for reference.
