摘　　要：应用连续梁分析方法讨论了三缸内燃机的平衡性能，证明了在飞轮和皮带轮上适当增加一部分平衡重或适当选取各曲拐的平衡百分比，可以有效地改善发动机的整机平衡性能和减小曲轴的弯曲变形。The equilibrium characteristics of a three-cylindered engine are ana-lyzed by means of continuous beam, It is confirmed that proper addition of a cer-tain balance mass to the flywheel and the belt pulley or careful selection of the balance percentage of each crank may effectively improve the equilibrium charac-teristics of the engine,and reduce the bending deformation of the crank shaft.

关 键 词：内燃机 平衡 连续梁
