| 摘 要： | 运用GT-Crank软件,建立直列4缸发动机模型,以发动机y方向二阶往复惯性力为优化目标,以平衡轴的结构参数为设计变量,进行仿真及DoE分析,并由DoE优化设计的结果设计计算平衡轴的结构尺寸。仿真数据表明,加装平衡轴后,y方向二阶往复惯性力大幅降低。

| Abstract: | The model of in-line 4-cylinder engine was built with the GT-Crank software.Aiming at optimizing the 2nd order reciprocating inertia force along Y direction,the simulation and DoE analysis were carried out by changing the structural parameter of balance shaft.With the optimized result,the structural size of balance shaft was calculated.The results show that the 2nd order reciprocating inertia force along Y direction decreases greatly after mounting the shaft balance. |
