摘　　要：基于Top-Down设计思想,运用知识工程内涵,提出基于知识的汽轮机叶片锻模自顶向下设计方法。在锻模设计中,首先考虑锻模要实现的功能,建立总体结构概念模型的初步方案,然后再考虑实现该功能所需的具体结构,结合设计过程知识自顶向下驱动其设计自动化过程,完成各部分的详细设计。基于知识的锻模自顶向下设计方法最大限度地满足了新模式下对锻模功能和结构的要求,减少在设计中的主观错误,有利于提高锻模设计质量与效率,而且使工程设计人员可以更多地关注锻模的功能和装配结构协调性。Based on the idea of Top-Down design and the connotation of knowledge engineering,this paper proposes a knowledge-based top-down design method for turbine blade forging die.In the forging die design,the paper first considers the function of the forging die to achieve,establishes a preliminary scheme of the conceptual model of the overall structure,and then considers the specific structure required to achieve the function.Combined with the design process knowledge from the top down to drive its design automation process,the detailed design of each part is completed.The Top-Down design method of forging die based on knowledge satisfies the requirements of forging die function and structure to the greatest extent under the new mode,reduces the subjective errors in the design,it is beneficial to improve the quality and efficiency of forging die design,and enables engineers to pay more attention to the coordination of forging die function and assembly structure.
