“…In a recent study, 14 it was reported that the variabilities in the material parameters of each brake component are very low, whereas the variability in the elasticity modulus of the friction lining is relatively high. 42 Also, in several other studies, 9,13,20 it was pointed out that the friction and the contact are the major sources of uncertainties in the brakes.…”

“…8 The probabilistic method is the most common technique for quantifying the uncertainties of the brake system employed in the literature. For example, Sarrouy et al 9,10 presented random simulations to improve the efficiency and the accuracy of linear or non-linear squeal analysis based on polynomial chaos expansions; Tison et al 11 and Nechak et al 12 presented a complete strategy or sensitivity analysis to improve the prediction of squeal simulations by introducing the random uncertainty and robustness concepts; Nobari et al 13 presented an efficient random method of uncertainty propagation for squeal instability analysis via Kriging models; Renault et al 14 improved the correlation between the experimental prediction and the numerical prediction of unstable frequencies by considering the detected uncertainty in brakes. These probabilistic studies based on a random method have achieved significant successes in brake squeal analysis, and they have greatly promoted the development of non-deterministic analysis of the squeal problem.…”

On the basis of fuzzy random variables, a universal approach to squeal analysis of the disc brakes involving various types of uncertainty is proposed in this paper. In the proposed approach, first, the brake stability analysis function related to reliability is constructed with fuzzy random variables. Next, the fuzziness represented by fuzzy random variables is decomposed into interval uncertainties by using a level-cut strategy. Then, the expectations and the variances of the brake stability analysis function are approximately solved by the random moment method at different cut levels, and the lower bounds and the upper bounds of the expectations and the variances are calculated by using a first-order Taylor expansion and a subinterval analysis. Finally, by combining the different interval solutions with the corresponding cut levels, the fuzzy solutions of the brake stability analysis function are obtained, which can be employed to evaluate the brake squeal instability. The proposed approach provides a universal framework for dealing with various types of uncertainty that may exist in automotive brakes. The universality, the accuracy and the efficiency of the proposed approach to the squeal instability analysis of the brakes involving various types of uncertainty are verified by the analysis results from nine different numerical examples.

“…Even with the scientific literature being rich in studies regarding the behavior of vehicles brake systems under changing operating conditions [10][11][12], it is surprising that, to the best of authors' knowledge, no similar research description on lift brakes has been reported up to the present date. Only general provisions contained in the British Standard Document BS EN 81 [13,14] are to be found.…”

Robust optimization and uncertainty quantification in the nonlinear mechanics of an elevator brake system

et al. 2019

View full text Add to dashboard Cite

This paper deals with nonlinear mechanics of an elevator brake system subjected to uncertainties. A deterministic model that relates the braking force with uncertain parameters is deduced from mechanical equilibrium conditions. In order to take into account parameters variabilities, a parametric probabilistic approach is employed. In this stochastic formalism, the uncertain parameters are modeled as random variables, with distributions specified by the maximum entropy principle. The uncertainties are propagated by the Monte Carlo method, which provides a detailed statistical characterization of the response. This work still considers the optimum design of the brake system, formulating and solving nonlinear optimization problems, with and without the uncertainties effects.

“…7,20 Generally, two methods are widely used to investigate brake squeal, i.e. experimental tests 8,[21][22][23][24][25][26][27] and the FE method. [28][29][30] Many scholars have examined the squeal noise of brake systems by combing both methods, [31][32][33][34][35][36][37][38][39][40] considering that both experimental tests and the FE method have their own merits and demerits.…”

In this research, the tribological and dynamical characteristics of a brake pad with multiple blocks are investigated using experimental and numerical methods. A dynamometer with a multiblock brake pad configuration on a brake disc is developed and a series of drag-type tests are conducted to study the brake squeal and wear behavior of a high-speed train brake system. Finite element analysis is performed to derive physical explanations for the observed experimental phenomena. The experimental and numerical results show that the rotational speed and braking force have important influences on the brake squeal; the trends of the multiblock and single-block systems are different. In the multiblock brake pad, the different blocks exhibit significantly different magnitudes of contact stresses and vibration accelerations. The blocks located in the inner and outer rings have higher vibration acceleration amplitudes and stronger vibration energies than the blocks located in the middle ring.
