摘　　要：针对锻压机床床身的制造过程和结构特点,围绕床身铸件铸造过程温度场、应力场的分析与计算,铸造热应力拓扑优化模型和设计准则的建立,锻压机床床身结构拓扑与尺寸协同优化算法的建立等方面展开研究和阐述,综合考虑床身铸造过程热应力、温差和热变形的影响,实现锻压机床床身结构拓扑与尺寸的协同优化过程。Aiming at the manufacturing process and structure features of forging machine bed, this paper re- searches and reviews on such aspects as the analysis and calculation of temperature and stress field of the bed in the casting process, the establishment of topology optimization and design principle under casting thermal stress, the algorithm of collaborative optimization of structure topology and size for forging machine bed and so on. The influence of thermal rensive consideration during stress, difference in temperature and thermal deformation are taken into comph- the casting process on the bed to realize the process of collaborative optimization.
