摘要

汽车噪音和振动的主要来源之一是变速箱。轴、齿轮和轴承是汽车变速箱产生噪音和振动的主要原因。各种研究报告表明,振动的根本原因是轴承激励。除了轴承的致命缺陷或极端结构共振放大外,齿轮啮合也是高频振动和噪声的主要来源,即使在新建的设备中也是如此。齿轮损坏检测对汽车变速箱和车辆安全至关重要。此外,由轴不平衡、轴错位和其他因素引起的振动也会在传动系统的传输路径中产生噪声和振动。此外,汽车变速箱的振动与不良设计、施工质量和生产精度密切相关。本文回顾了以往对传统车辆的汽车变速箱的研究和方法。很明显,频率分析和阶次分析常用于汽车变速箱的噪声和振动分析。包络分析通常用于分析轴承故障。最后,还回顾了滚动体轴承诊断技术。

Methods of detection and localization of the sources of noise and vibration on car gearboxes: a review
One of the primary sources of noise and vibration in automobiles is gearboxes. Shafts, gears, and bearings are the main causes of noise and vibration in vehicle gearboxes. Various studies have reported that vibrations’ root cause is bearing excitation. Besides bearing fatal defects or extreme structure resonance amplification, gear mesh is the primary source of high-frequency vibration and noise, even in newly built units. Gear damage detection is frequently crucial in automotive gearboxes and vehicle safety. Furthermore, vibrations caused by shaft imbalances, shaft misalignments, and other factors can cause noise and vibrations in the drivetrain's transfer path. In addition, the vibration of an automobile gearbox is closely related to poor design, construction quality, and production accuracy. This paper reviewed previous research and methods on car gearboxes for conventional vehicles. It was obvious that frequency analysis and order analysis were commonly used in noise and vibration analysis on car gearboxes. Envelope analysis is usually used to analyze bearing faults. Finally, rolling-element bearing diagnostic techniques were also reviewed.
