摘　　要：内燃机作为动力系统的核心,其性能的优劣很大程度上取决于所用材料的高温压缩成形特性。本文针对内燃机用材料在高温条件下的压缩成形特性进行了深入分析,建立了HastelloyC276筒形件热强旋的有限元模型,揭示了不同旋压参数下筒形件的微观组织演变规律。随着旋压温度的增加,筒形件的成形精度逐渐升高;在较高的进给速率、较低的主轴转速下,筒形件易发生起皱、损伤开裂等现象。为内燃机的设计和材料选择提供了重要的理论支持和实践指导。As the core of the power system,the performance of the internal combustion engine depends largely on the high-temperature compression molding characteristics of the materials used.In this paper,an in-depth analysis of the compression molding characteristics of materials used in internal combustion engines under high temperature conditions is carried out,and a finite element model of HastelloyC276 cylindrical parts hot spinning is established,which reveals the microstructure evolution of the cylindrical parts under different spinning parameters.With the increase of the spinning temperature,the molding accuracy of the cylindrical parts gradually increases;under the higher feed rate and lower spindle speed,the cylindrical parts are prone to wrinkling,damage cracking and other phenomena.It provides important theoretical support and practical guidance for the design and material selection of internal combustion engines.
