汽车传动系动平衡测试及控制研究
Measurement and Control of Driveline Imbalance for a Vehicle
摘要 研究了汽车传动系的动平衡测试和控制方法,并建立了动平衡的测试流程.通过阶次分离方法来确定汽车变速箱的档位,用相位稳定方法确定平衡转速,然后对试重块大小和位置的选择进行分析,并通过实测数据验证了该方法的准确性及可靠性.对系统等效面的动平衡构成因素进行了深入分析和计算,指出等效面的动平衡主要由部件不平衡、装配和其交叉影响因素构成.通过矢量叠加理论分析出采用等直径螺栓孔的连接法兰,部件控制综合跳动,装配时采用标记对点匹配方法,可以有效改善传动系动平衡引发的NVH问题,最后通过实车测试进行了效果验证.
Abstract:
The imbalance test and control methods of a vehicle driveline system are studied,and the imbalance testing process is established.In the vehicle,the order separation method is used to determine the transmission gear,and the phase stabilization method is used to determine the balancing rotation speed in the first time.Then,the balance test mass and location are analyzed.The method is verified by the test data.Through analysis and calculation,it is pointed out that the imbalance mass of equivalent plane is mainly composed of component imbalance,assembly and cross-talking factors.The force vector synthesis shows that it can effectively improve the NVH problem of driveline imbalance with an equal angle bolt hole,control the composite flange run-out (CFRO)and match the light point and the heavy point.The measurement result shows that the control method is very effective.
