Design of Composite Brakes Using Knowledge-Based Design Methodology

Abstract

In designing modern friction materials that are normally made of composite materials, a more systematical approach is needed in order to select the most appropriate composition of raw materials for specific applications. Here, knowledge-based design methodology has been formulated for composite brake design application, that consists of: design database generation from experiments, metamodelling, and global optimization processes. The objective function has incorporated, among others, the uncertainties introduced in the experimentally-obtained design database, so that providing the optmization results with the information of variation. The application of the methodology has been demonstrated to two cases, i.e. train brake and motorcycle brake pad, with the optimization results close to the targetted values and the information of output variation, as intended.

Effect of Phenolic Resin and Alignment to the Quality of Prototype Composite Railway Brake Blocks

“…The methodology is divided into 3 stages of the process such as database design, metamodeling and optimization. In this application, the methodology are using experimental data, metamodeling techniques are using Radial basis function (RBF) and the optimization stage are using memetic algorithm optimization (MA) [5,7]. In general, design process sequence performed as shown in flow charts Figure 2.…”

“…Figure 2. Knowledge Based Design method [5,7] The calculation of the dependent function is an important step in the extension evaluation method. If it is assumed there is an interval = 〈 , 〉 at the point ∈ then the dependent function at any point is ∈ −∞, +∞ where the interval X and the point M are defined as follows [6,8]:…”

“…Another thing to be effected to mechanical properties is process procedure. Alignment of dies could Optimation methodology to get optimum composition of material have been developped before by Yulianto [5] and Hilman [6]. The results of their research were used as references to make prototype of railway brake blocks.…”
