| 摘 要： | 为了确定内燃机运动机构最佳动力学特性的停缸方案,建立某V8柴油机曲轴系统、正时齿轮和配气机构柔性动力学耦合仿真模型,通过试验进行相应模型的校核.进行不同单缸停缸方案的运动机构动力学仿真.结果表明,停缸后曲轴角位移幅值明显增加,且以低谐次滚振为主；凸轮轴角位移无明显变化,但配气机构运动特性恶化,机械负荷增大.选择曲轴单双...

| Abstract: | In order to confirm cylinder deactivation schemes with preferable dynamic performances of internal combustion engine motion mechanisms,the flexible dynamic model of a V8 diesel engine was established,which coupled mechanisms such as cranktrain,timing-gears,and valvetrain.The dynamic models were validated by experimental data.Motion mechanisms dynamic simulations were conducted for single cylinder deactivation.The results revealed that angular displacement amplitude of crankshaft obviously increased when sin... |
