    摘要:

    针对单个齿轮副和变速器总成两方面的敲击特性,笔者利用专用的敲击试验装置测试多工况敲击相关数据。首先,对振动噪声数据进行有效能量叠加处理和对轮副在啮合线方向上速度差标准差的计算,得到单个齿轮副和变速器总成的敲击特征曲线;次,提取相应的特征参数分别建立单个齿轮副和变速器总成的敲击特性量化评价指标向量;最后,用量化评价指标对某5档变速器的敲击问题进行了量化分析及问题点确定,并对优化前后的变速器进行了敲击性能量化对比。结果表明:量化指示与主观评价结果有较好的一致性,证明量化评价指标对变速器敲击问题优化和评价具有一定的指导意义。

    Abstract:

    Based on the rattle characteristic of gear pair and transmission assembly, a study on establishing quantitative evaluation indexes of rattle characteristic for transmissions is conducted. The test is conducted in a semi-anechoic laboratory. The experimental device is mainly used to test the vibration and noise of the transmission. The drive motor is a high dynamic permanent magnet motor with special torque-rotation characteristics, which can be used to simulate the gas pressure of internal combustion engine and reciprocating inertial force of piston, in order to realize the output torque characteristics of the engine. The rattle characteristic curves of gear pair and transmission assembly are obtained by calculating the standard deviation of velocity difference and energy superposition processing to transmission case vibration data, respectively. The evaluation index vectors of the rattle characteristic are built up by extracting the characteristic parameters from two characteristic curves. They are used for rattle problem analysis of a five speed transmission, and for comparative evaluation to the rattle performance of the transmission before and after optimization. The evaluation results show a good agreement with the subjective evaluation.
