Sampling of Parameters to Predict and Consider their Variation During Application by Simulation

"Numerical method procedures for brake system analysis are widely accepted in industry. Using simulations in an early design stage reduces time to market, saves costs, improves the physical behavior of the brake system and makes it possible to reduce physical prototypes. By reducing the number of prototypes, the importance of the simulation is constantly increasing. The simulation must cover the entire range of conditions of the component in order to guarantee a reliable function in every state. This requires to vary parameters in a wide range and to check all combinations to detect the possible disadvantageous. It follows that the number of variants increases and the run time of the simulation becomes more important. The two main factors for accepting the large number of variations are computation time and ease of use. For ease of use, it is assumed that the simulation software itself provides functions for parameter variation, i.e. automatic sampling. This prevents different software from having to be used in combination. Incompatibilities and errors in communication can thus be excluded. The run time can be kept low by an outstanding basic performance. In addition, the software should also take advantage of the similarity of the variants in order to enable further reduction in run time. In addition, unnecessary calculation steps that are not required for a repetition should be automatically omitted. The variation of different parameters is shown on the basis of brake calculations. The availability of many parameters, also for the non-linear simulation, is shown. Examples of run times for industrial application of a brake disk shows the usability of this approach for standard workflows. "
