摘要/Abstract

摘要： SiCp/A356制动盘与合成闸片摩擦副在制动过程中出现了摩擦面划伤及制动噪声等问题。通过缩比试验与仿真相结合的方法，以SiCp/A356制动盘配副合成闸片为研究对象，开展了合成闸片的结构优化设计及不同合成闸片材料的摩擦特性研究。缩比台架试验发现闸片两侧径向沟槽较周向沟槽磨屑堆积严重，切入端较切出端磨屑堆积严重。基于流场仿真分析，闸片沟槽内涡旋气流区域的空气流动较差，容易产生磨屑堆积。基于正交试验及Box-Behnken试验设计的响应面分析，以提高合成闸片空气质量流量且不降低对流换热系数为目标，优化了闸片结构设计，优化后闸片的空气质量流量提升了28.22%、对流换热系数提升了1.34%，排屑性能和散热性能均得到提升，同时制动噪声倾向性降低，不稳定倾向系数降低了49.53%。基于优化的闸片结构，开展SiCp/A356复合材料分别与三种合成材料配副的摩擦匹配性研究，发现FANY材料与928W材料均具有良好的第三体层、低磨损量和稳定的平均摩擦系数，FANY材料制动噪声最低。

Abstract: The friction pair of SiCp/A356 brake disc and synthetic brake pads often have problems such as friction surface scratches and brake noise during braking. The synthetic brake pads paired with SiCp/A356 brake discs are selected as the research object. Structural optimization design of the synthetic brake pad and friction characteristics of different synthetic brake pad materials are investigated using a combination of scale bench testing and simulation methods. Scale bench tests reveal that debris accumulation in radial grooves on both sides of the brake pads is more severe than in circumferential grooves, while accumulation in the cut end exceeds that in the non-cut end. Through flow field simulation analysis, airflow in the vortex airflow region within pad grooves is identified as insufficient, leading to debris accumulation tendencies. Response surface analysis based on orthogonal testing and Box-Behnken test design is employed to optimize pad structure design, aiming to enhance air mass flow rate without reducing convective heat transfer coefficient. The optimized synthetic pad increases the air mass flow rate by 28.22%, the convective heat transfer coefficient by 1.34%, the performance of chip removal and heat dissipation are improved, the coefficient of tendency of instability is decreased by 49.53%, and brake noise tendency is reduced. Friction matching between SiCp/A356 composites and three synthetic materials is examined using the optimized brake pads structure. FANY and 928W materials are found to maintain stable third body layers, demonstrate low wear rates, and exhibit stable average friction coefficients, with FANY material showing the lowest braking noise levels.
