摘要

车辆的乘坐舒适性受动力总成扭转振动的影响很大。本文提出了动力总成扭转振动的多工况、多指标评价方法,根据不同工况的特点选择不同的评价指标。首先,分析动力总成的扭转振动激励源。选取的指标有:用均方根值求得的速度振幅值、振动剂量值、峰峰值、隔振率([公式:见正文])和速度波动衰减率([公式:见正文])。其次,分析点火、怠速、启动、加速、减速、从 "尖入 "到 "尖出 "切换时的扭转振动特性,确定各工况的扭转振动评价指标。然后测试优化前后双质量飞轮(DMF)的扭转特性,并根据选定的工况对车辆进行测试。最后,通过去除提取数据中的趋势项,得到速度振幅,从而计算出各工况的评价指数。试验结果表明,DMF 优化后阻尼性能得到改善,不同工况下的评价指数普遍提高了约 7%,且各工况下的指数大小呈相同趋势,验证了多工况、多指数方法评价的可行性,为动力总成扭振评价提供了参考。

Experimental evaluation of the torsional vibration characteristics of a dual-mass flywheel based on multi-condition and multi-index methods
Vehicle ride comfort is significantly influenced by powertrain torsional vibration. A multi-condition and multi-index evaluation method of the torsional vibration of the powertrain is proposed in this paper, which selects different evaluation indices according to the characteristics of different working conditions. First, the torsional vibration excitation source of the powertrain is analyzed. The selected indices are the speed amplitude value obtained with the root mean square value, the vibration dose value, the peak-to-peak value, the vibration isolation rate ([Formula: see text]), and the speed fluctuation attenuation rate ([Formula: see text]). Second, the torsional vibration characteristics of ignition, idle, startup, acceleration, deceleration, and switching from tip-in to tip-out are analyzed, and the torsional vibration evaluation indices of each working condition are determined. Then the torsional characteristics of a dual-mass flywheel (DMF) are tested before and after optimization, and the vehicle is tested according to the selected working conditions. Finally, by removing the trend term in the extracted data, the speed amplitude is obtained to calculate the evaluation indices for each working condition. The test results show that the damping performance is improved after the optimization of the DMF, and the evaluation indices under different working conditions are improved by approximately 7% in general, the magnitude of the indices under each working condition showed the same trend, which verifies the feasibility of the evaluation for the multi-condition and multi-index methods and provides references for evaluating the torsional vibration of the powertrain.
