摘　　要：在新型二冲程微型摆式内燃机(MFSPE)的设计及完善过程中,温度场分析占有重要地位。从数值计算所得的燃烧室周期温度曲线中,均匀提取32个载荷点,基于ANSYS软件按32个载荷步进行载荷施加及求解分析,得出了缸体各载荷步的温度场等效云图,并对部分有代表性的图从温度场的角度进行分析,提出了缸体改进设计的建议。Temperature field analysis is very important in the course of design and perfection of the Novel Two- stroke Micro Free Swing Piston Engine. Thirty-two Temperature load dots are drawn evenly from the cycle temperature curve plotted in the number value calculating stage. With ANSYS software, thirty - two load steps are defined and solved, and the temperature field cloud chart of all load steps of the cylinder block has been drawn, then the key pictures are analyzed. Some existing problems and the improved suggestion are put forward further.
