Brakes are one of the most important safety and performance components in automobiles. Furthermore, the necessity of refinement of vehicle acoustics has noticeably increased. Using optiSLang, already in an early design phase, a main focus is on the prevention of squealing brakes by vibration simulation. Thus, a profound understanding of the phenomena is obtained.

Product development in the consumer goods industry
e43c1b6d1e In the consumer goods industry, the focus is on a variety of materials and mechanical components with different operational demands. The production of traditional prototypes is a costly process. By coupling the finite element methods with the stochastic optimization software optiSLang, the virtual product development becomes much more automatic and prototyping is optimized by considering process- and material-based scatters and tolerances.

e2d2c38b17 Turbo machines consist of many rotating and stationary parts and therefore show a high potential for optimization. In order to handle the complexity of such an RDO task, an iterative decoupled loop approach in combination with the identification of the most significant random and design variables, using multivariate statistics, is necessary. optiSLang provides the ability, by conducting a robustness evaluation, to prove the predictive capability of the simulation model and to identify the most important parameters to examine efficiently a reliability analysis.

a3db301764 CAE-based robust design optimization supports the process and planning of forming parts. Applied in an early phase of virtual product development, the robustness of the forming process considering tolerances and variations will be increased. For graphical analysis of variations and correlations of the robustness analysis, Dynardo developed the post processor SoS (Statistics on Structure). In combination with optiSLang and a finite element forming simulation program, an efficient process chain of robust design optimization can easily be implemented into the forming process.

37b3836047 Sensitivity analysis is suitable to correlate uncertainties in model response variables with the model input parameters. Within a robustness evaluation using virtual models, with the help of a sensitivity analysis, the major responsible input variables are identified in the case of non-robust behavior of the system and appropriate reactions can be meaningfully applied. This method is used conducting a robustness evaluation of various car body structures in the automotive industry. For evaluation, sheet metal thicknesses are varied and the sound pressure level is examined depending on different frequencies.

Optimization of electronic devices and components

Electromagnetism deals with the transmission of signals and information by electromagnetic waves. Depending on the application, it is intended either to minimize (e.g. circuit board design) or to maximize (e.g. antenna design) the signal radiation. For analysis and optimization, circuit and field simulations are conducted to generate behavior models as a knowledge base for creating optimal designs. A sensitivity analysis with optiSLang helps to identify the parameters with significant impact on the objective function. Also, electronic components exposed to thermal or mechanical loads (e.g. electronic control modules in the automotive industry or electrical drives) are analyzed with optiSLang. Thus, the best design for pre-defined load conditions can be found already at an early stage of product development.

Also in biomechanics, the CAE-based optimization and stochastic analysis contributes to the success of research and development. For example, at Cortronik, with the help of optiSLang, the design of vascular prostheses (stents) have been analyzed and optimized, taking into account scatters due to production and material tolerances. There are also application fields to optimize surgical techniques in breast reconstruction for cancer patients and surgical treatment of fractures.
