“…One of the earliest bicycle disc brake design can be seen in Figure 22 [48]. Like other hub brakes, disc brakes are further away from other debris or mud when compared to the wheel rims as even the brake pads are retracted while remaining close to the disc itself, hence there is very little chance that any sort of debris would be trapped between the braking surfaces than there is between rim brakes [49]. Brake discs are harder than wheel rims, and disc brakes' pads are harder than rim brakes' blocks, so greater braking force can be used without the risk of excessive wear to the wheel rim [4, p. 289].…”

“…Thereby, a better understanding and prediction of the propensity of squeal noise in car brake systems is an important challenge that is faced by the automotive engineers. For example, many studies on Finite Element Models (FEM) for automotive brake squeal have been conducted in recent years [1][2][3][4][5][6][7][8]. Different methodologies are available to predict such phenomenon and two main categories are distinguishable: the dynamic transient analysis and the Complex Eigenvalue Analysis (CEA).…”

“…Then, they realized an optimization to identify a robust design. In 2017 [5], they used fuzzy logic combined to interval analysis in order to quantify the uncertainty in a FEM of a brake system. In 2017, Do et al [22] used the fuzzy logic to manage the frictional contact problem in a numerical strategy to perform more rapidly multiple CEA and so the prediction of brake squeal.…”

Many numerical simulations have been dedicated to the brake squeal prediction by considering the predominant influence of the frictional interface between the pads lining and the disc. However, many others contact interfaces are present in an automotive brake system. Nowadays, the influence of the state of these contacts on the stability behavior of an automotive brake system and thus, on the squeal propensity is not yet well understood.This paper attempts to provide a huge investigation on the sensitivity of squeal propensity to the various contact interfaces between pads, piston, bracket and caliper. The main contribution of the present study aims not only to give a better understanding on the role of these numerous contacts in an automotive brake system but also to propose a strategy based on genetics algorithms in order to reduce the number of simulations to achieve by ranking the effects of all the independent contact states in a pre-design process.

“…In many cases, uncertain factors are inherent in mechanical systems and uncertainty widely exists in the system parameters. 8,9 As the design requirements of automobiles are becoming more and more complex, the design results based on deterministic techniques cannot meet the desired requirements well, so the uncertainty of parameters in a PMS should be taken into account.…”

Uncertainty widely exists in the powertrain mounting system of a vehicle. The traditional analysis and optimization methods for powertrain mounting system design are often based on deterministic or random models. In this study, an efficient analysis and optimization method is developed for powertrain mounting system design involving interval uncertainty. In the proposed method, the uncertain parameters of powertrain mounting system are treated as interval variables, and an efficient method called as Chebyshev-Vertex method is developed to fast calculate the lower and upper bounds of the natural frequencies and decoupling ratios of powertrain mounting system. Monte-Carlo method is taken as a reference method to verify the calculation. Then, an optimization model is established based on Chebyshev-Vertex method, in which the interval responses of decoupling ratios are used to build up optimization objective while the interval responses of natural frequencies and decoupling ratios are taken to create optimization constraints. The optimization model of the powertrain mounting system with interval parameters is generally a double-loop nested problem, and it is rather time-consuming on calculation. However, based on Chebyshev-Vertex method, the optimization model can be approximately simplified into a single-loop one and the calculation efficiency is greatly improved. A numerical example is provided to demonstrate the effectiveness of the proposed method on the analysis and optimization design of the powertrain mounting system involving interval uncertainty.
