综合考虑变速器的输入转速波动、结构特点及齿轮啮合特性等因素,同时计入变速器壳体的柔性特征,合理设置边界条件,建立变速器齿轮敲击刚柔耦合仿真分析模型。以空套齿轮角速度为目标,通过台架试验检验了所建模型的有效性。依据敲击产生机理提出基于主、从动齿轮转速波动矢量和变化的敲击客观评价指标。基于校验后的仿真分析模型,在敲击工况下对常用的Jerk指标和提出的敲击客观评价指标进行计算分析,并与主观评价结果进行了对比。结果表明,提出的基于主、从动齿轮转速波动矢量和变化的敲击客观评价指标与主观评价结果具有良好的一致性。为敲击噪声客观评价提供了方法参考。
Taking into account factors such as input speed fluctuation, structural characteristics and gear meshing characteristics of the transmission, the flexible characteristics of the transmission box are considered, boundary conditions are properly set up, and transmission gear rattle rigid-flexible coupling simulation analysis models are established to reproduce the gear rattle. Then, refer to speed of idle gears, the effectiveness of the analysis model is verified by bench test. According to the gear rattle mechanism,gear rattle evaluation index based on the speed fluctuation vector sum of the driving and loose gears is proposed. Based on the validated simulation model, jerk and speed fluctuation vector sum evaluation indicators are calculated and analyzed under the gear rattle conditions, and comparing with the subjective evaluation results. The results show that the speed fluctuation vector sum of the driving and loose gears has good consistency with subjective evaluation result. It provides a methodological reference for the objective evaluation of gear rattle noise.
