摘　　要：文章对V型8缸发动机进行了平衡分析,进一步应用优化设计理论,对平衡轴进行了优化设计,并设计出改进后的平衡轴。使该平衡机构基本上完全平衡了二次往复惯性力,而且最大可能地消减了倾覆力矩。改进后的平衡轴外型尺寸小,质量轻,可有效减小发动机的振动激励力,改善发动机的振动品质。本平衡方案极大地改善了该发动机的振动特性。The paper analyzes the balance performance of V-eight, with the help of the optimal design theory, designs a new balancing axis, the balancing mechanism of which can balance the secondary reciprocating inertia force and greatly reduce the lifting moment. The improved axis is small and light, it can effectively reduce the vibration exciting force and improve the vibration quality of engines. The plan will greatly improve the vibration characteristics of V-eight.
