“…For example, in 2014, the European Union drafted a new automotive noise bill, which was implemented in three stages, to gradually reduce the noise limit requirements for ordinary automotive from 74 dB to 68 dB and for heavy trucks with capacities of over 12 tons from 81 dB to 79 dB [1]. Brake noise is an important part of automotive NVH; it not only causes environmental pollution but also greatly reduces automotive ride comfort [2]. The problem of brake noise has always been an important research topic, with the earliest work dating back to the 1930s.…”

A limited number of studies have explored drum brake noise with uncertainty. Therefore, a new method for the robust design of drum brakes is presented herein on the basis of complex modal analysis and Taguchi's robust design. Based on the finite element method, complex modal analysis is used to predict drum brake noise. Taguchi's robust design is adopted to reduce drum brake noise and improve system robustness. In this method, the Young's moduli of the brake drum, brake shoes, and friction lining are considered as control factors, the friction coefficient and brake pressure are taken as noise factors, and the weighted instability tendency coefficient is regarded as the objective function. When the proposed method is applied to drum brake design, drum brake noise is significantly reduced and system robustness is increased. Specifically, the signal-to-noise ratio increases by 62.94%, and the average value of the weighted instability tendency coefficient decreases by 91.7%.

“…Finally, the numerical calculation results showed that the brake noise increased with an increasing braking force and a decreasing braking speed [17]. To solve the issue of automotive brake noise, Jung et al found the relationship between patterned surfaces and brake squeal through the numerical methods, and it was found that the cross-drilled machining patterns were concluded to be an influential factor for in-plane mode frequency while the slotted patterns had more leverage for out-of-plane mode frequency [18].…”

Brake pads of disc brake play an important role in the stable braking process of a large-megawatt wind turbine. There is always vibration, screaming, and severe nonuniform wear under the effect of both retardation pressure and friction. To solve these issues, this article aims to find a new structure of the brake pads to improve brake performance. A multiobjective structure topology optimization method considering thermal-structural coupling and brake vibration is carried out in this article. Based on topology optimization method of Solid Isotropic Microstructures with Penalization (SIMP), the compromise planning theory is applied to meet the stiffness requirement and vibration performance of brake pads. Structure of brake pads is optimized, and both the stiffness and vibration performance of brake pads are also improved. The disadvantages of single-objective optimization are avoided. Thermal-structural coupling analysis is tested with the actual working conditions. The results show that the new structure meets the stiffness requirement and improves the vibration performance well for the large-megawatt wind turbine. The effectiveness of the proposed method has been proved by the whole optimization process.
