摘要
车内变速器噪声直接影响整车的舒适性。对现有变速器噪声控制技术进行综述,按噪声频率特性介绍了变速器高频啸叫噪声、中频敲击噪声、低频振动噪声的产生机理及传递路径。研究表明:优化壳体结构、粘贴吸声材料可削弱啸叫噪声的辐射,齿轮微观修形可改善齿轮啸叫噪声,且具有效率高、成本低的特点,是未来的研究热点;调整扭转特性参数、合理增大空套齿轮拖拽力矩能有效抑制敲击噪声,后续需考虑温度对齿轮变形的影响;双质量飞轮在控制发动机转速波动方面性能优异,未来可进一步改进双质量飞轮设计、优化发动机标定程序;改变壳体固有频率、优化齿轮参数是降低振动噪声的有效手段,但油泵及金属带振动噪声的控制方法较少,同时需要考虑润滑油液对振动噪声的影响;未来高效、高精度控制变速器噪声技术的应用离不开智能优化算法的加持。
Transmission noise directly influences the comfort of the entire vehicle.This paper reviews the existing transmission noise control techniques,and introduces the mechanism and transmission path of high-frequency whine noise,mid-frequency clashing noise and low-frequency vibration noise according to the noise frequency characteristics.Research shows that optimizing the transmission housing structure and applying sound-absorbing materials can reduce the radiation of whine noise.Micro-texturing of gears is efficient and cost-effective for improving gear whine noise,and is expected to be a future research hotspot.Adjusting torsional characteristic parameters and reasonably increasing the drag torque of idler gears can effectively suppress clashing noise.The influence of temperature on gear deformation needs to be considered in future studies.The dual-mass flywheel performs well in controlling engine speed fluctuations,and future research can focus on improving the design of the dual-mass flywheel and optimizing the engine calibration program.Changing the natural frequency of the housing and optimizing gear parameters are effective approaches to reduce vibration noise,however,there are fewer methods controlling oil pump and strap vibration noise,and the influence of lubricating oil on vibration noise should also be considered.The application of future high-efficiency and high-precision transmission noise control technologies will rely on the support of intelligent optimization algorithms.
