摘要
多学科优化方法(MDO)可以弥补传统优化的不足,有效解决复杂优化问题,提高工程项目的设计和优化效率。针对柴油机曲柄连杆机构多学科部件优化问题,综合考虑曲轴和连杆两部件,采用协同优化方法,建立了相应的多学科优化数学模型,并基于ISIGHT软件构建多学科优化平台,进行了曲柄连杆机构多学科综合优化计算。研究结果表明,采用多学科优化方法可以实现曲轴和连杆的耦合和高效优化,使两个部件同时达到最优,改善了其质量和应力特性。
Multidisciplinary design optimization（MDO） can compensate for the lack of traditional optimization,solve the problem of complex optimization and enhance the efficiency of design and optimization.In order to solve the MDO problem of crank and connecting rod mechanism,with comprehensive consideration of each discipline involved connecting rod and crank shaft,collaborative optimization was used,MDO model and the MDO platform based on ISIGHT was built.The results of research indicate that MDO method can realize the couple and high effect optimization of connecting rod and crank shaft,and the best results on both connecting rod and crank shaft are achieved,the mass and stress characteristic is improved.
