Effects of angle formation between melted zone and friction direction on thermal fatigue and wear resistance of truck drum brake

Abstract: The failure of grey cast iron drum brake is mainly caused by thermal fatigue crack running through the top along the axial direction, which has the characteristics of regional failure. By using the advantages of laser fabrication technology, the single models with five different angles combined with the anti-crack ring were designed. The optical microscope, scanning electron microscope and X-ray diffraction were used to characterize the microstructure and phase of the drum brake material grey cast iron and the… Show more

“…According to the theory of the Subsection 2.3 and the results of the Subsections 4.1 and 4.2, the RBROD of the drum brake is carried out. In this paper, the sub-objective functions of RBROD are defined as in Equations (11)(12)(13), where 𝑓 1 (𝑋) is the 2-norm of the reliability sensitivity of the mean values of the design parameters 𝑋, 𝑓 2 (𝑋) the 2-norm of the reliability sensitivity of the SD of the design parameters 𝑋, and 𝑓 3 (𝑋) is the weight function of the drum brake.…”

“…The thermal fatigue crack is a main failure mode of drum brakes, 13 so multiple scholars have conducted extensive studies for the thermal fatigue problem of vehicle brakes. To research the thermal fatigue properties of the brake drum materials as the vehicle is braking, Lu et al's 14 research studies the different cast iron, and Naji and Al-Nimr, and Natarajan et al 15,16 conduct the testing and the thermal analysis of a metal matrix composite brake drum under the single, continuous, and repeated braking, and the dynamic models of the predicted the temperature rise are established with the different braking.…”
