摘　　要：针对90,°V6柴油机强化后振动恶化的问题,对发动机平衡特性与平衡方案进行研究.经过发动机振动烈度台架测试结果校核,运用GT-Crank建立强化前发动机刚体动力学模型,在此基础上进行强化后模型计算.结合采用被动平衡与主动结构修改两类措施,提出不同的整机振动抑制平衡方案,包括平衡轴方案、错拐曲轴方案和错拐加平衡轴方案,对比分析3种平衡方案对整机振动的改善效果.结果表明:与其他两个方案相比,在保持柴油机总体型式与参数不变的前提下,采用平衡轴方案能更加有效地改善发动机的整机振动性能,是比较理想的平衡方案.To solve the worsened vibration problem of 90° V6 diesel engine after intensified, its balance and balance schemes were analyzed. Based on the vibration severity test result, the whole machine rigid-body dynamic model was built with GT-Crank software before intensified, and then the intensified engine model was computed. Using passive balance and active structure modification methods, different schemes were employed to lower the whole machine vibration severity, such as adding balancing shafts to the prototype, changing the crankshaft into split-pin crankshaft, and combination scheme of the above two schemes. Computational results of the above schemes show that the balance shaft scheme can improve the vibration characteristics more effectively than the others, and is a real-istic balance method.
