双质量飞轮式扭振减振器性能检测试验台的设计

摘要

The dual mass flywheel is a novel torsional damper in a position to depress effectively the torsional vibration and noise of the vehicle driveline. Domestic examination on dual mass flywheel is still in its infancy with no matured methods and means for performance testing. A design approach of performance testing station is put forward by analysis of vibration reduction principle of the dual mass flywheel and the establishment of a torsional oscillation model for the dual mass flywheel system. The test station features sound in adaptability, easy in testing process and high in detection efficiency, its application can effectively cut the danger in real vehicle detection of torsional oscillation reducer of dual mass flywheel. The outcome of the bench test reveals that it can detect effectively the torsional oscillation status of the transmission system to evaluate the damping effect of the dual mass flywheel and provide the references for the design of the dual mass flywheel and for the matching parameters in the design of engine-powertrain system.%双质量飞轮是一种新型的扭振减振器,能够有效地降低车辆传动系统的扭转振动和噪声.当前国内对双质量飞轮的研究处于起步阶段,尚无成熟的性能检测方法与手段.通过对双质量飞轮减振原理分析,建立了双质量飞轮系统的扭振模型,提出性能检测试验台的设计方法.试验台具有适应性强,试验过程易控制,检测效率高等特点,其应用可有效降低双质量飞轮式扭振减振器实车检测的危险.通过台架试验结果,验证其可以有效检测出传动系统的扭振状况,为双质量飞轮减振效果的评估、双质量飞轮的设计、发动机-动力传动系统参数的匹配性设计提供参考.
