摘要
制动鼓是商用车的关键部件,对于车辆的安全行驶有着至关重要的作用。制动鼓的健全性、致密度及显微组织均匀性均影响制动效果。主要从制动鼓材质、成型方式、铸造方法及铸造工艺等方面总结了制动鼓的发展现状;分析了制动鼓的失效形式及失效原因,并介绍了在制动鼓的疲劳寿命预测方面的研究进展。
Brake drum is a key component of commercial vehicle,which plays a vital role in the safe running of the vehicle.The soundness,density and microstructure uniformity of the brake drum all affect the braking effect.The development status of brake drum was summarized from the aspects of brake drum material,molding way,casting method and casting technology.The failure modes and reasons of brake drums were analyzed,and the research progress in fatigue life prediction of brake drums was reviewed.
