| 摘 要： | 针对某直列4缸发动机曲轴不同平衡方案，运用AVLEXCITEDesigner进行了仿真计算，得到了各方案下主轴承载荷随曲轴平衡率的变化情况：第1、3和第5主轴承的最大轴承载荷随着曲轴平衡率的增大而增大，而平均主轴承栽荷随着平衡率的增大而减小；第2、4主轴承的最大轴承载荷和平均轴承载荷随平衡率的增加变化不大，并通过计算结果对不同方案进行了比较。

| Abstract: | Using AVL EXCITE Designer, severalcrankshaft balance schemes for a four-cylinder in-line engine were simulated. The simulation result shows that forthe first, third and fifth main beaning, peak load is increasing with increasing crankshaft balance ratio, however, under this circumstance, the average load is decreasing. The variation for the second and fourth main bearingis much smaller. According to the calculation results, different schemes were compared. |
