Model Based System Engineering: From Requirements to Performance Optimization using SysML and modeFRONTIER

Appliances are expected to perform at higher levels due to increased regulatory requirements, greater connectivity, and greater competition in the marketplace. Quick delivery to market in a predictable time is needed to win with consumers before competitors do. Large global companies have to control parts proliferation to create global leverage. These are just a few of the reasons Whirlpool Corporation is taking a model-based System Engineering approach to managing the complexity of designing appliances by using the SysML modeling language.

Crystal Plasticity Modeling and Experimental validation with an orientation distribution function for Ti-7 al alloy

An optimization study is performed to identify the slip system parameters of Ti-Al alloys (Ti-0Al and Ti-7Al) using the available tension and compression experimental data showing the true stress - true strain curves of the alloys.

Vehicle occupant restraint system design under uncertainty by using multi-objective robust design optimization

The Multi-Objective Robust Design Optimization (MORDO) is employed for the vehicle occupant restraint system design. The optimization aims to improve the safety performance of the system and its robustness simultaneously.

Multidisciplinary optimization of the thermal and structural model of a building

Building energy performance largely depends on facade design and local weather characteristics. modeFRONTIER has been used - together with Rhino/Grasshopper plugin - to maximize winter radiation and minimize structural mass of a office building floor located in Toronto, Canada.

Process Integration and Optimization of ICME Carbon Fiber Composites for vehicle lightweighting: a preliminary development

Different from the Sheet Molding Compounds (SMC) structure, the unidirectional (UD) structure (laminate) has multiple layers, and each layer has anisotropic properties. The layout of each component in the vehicle structure needs to be optimized in order to achieve the optimum structure performance such as stiffness, durability, NVH, and safety. he multi-layer UD structure optimization is implemented on the platform of modeFRONTIER.

ESTECO webinar recording | Exploiting Design of Experiments (DOE) techniques for multibody and structural vehicle analysis with modeFRONTIER, Adams and MSC Nastran

On August 29th, 2017 ESTECO hosted expert engineers from MSC Software who demonstrated the advantages of the integration of their software in modeFRONTIER workflow to identify better solutions using Design of Experiment for multibody and structural vehicle analysis. 

Inverse analysis approach for determining the superplastic behaviour of the Titanium alloy Ti6Al4V-ELI

The characterization of the superplastic behaviour of the Titanium (Ti) alloy Ti6Al4V-ELI (Extra Low Interstitial), largely adopted for biomedical applications, was carried out by means of free-inflation tests: both tests at a constant pressure and alternatively varying the gas pressure between two levels (JP test) were performed. 

Multiobjective Sizing Optimization of a Steel Girder Bridge with a Simple Target–Driven approach

The structure considered in this study is a bridge consisting of four identical and equally–spaced steel girders with flanges welded to the web. The beams are supposed to bear a concrete slab, an asphalt layer and two sidewalks. ​A reference optimization is performed by using the modeFRONTIER MOGA-II algorithm in order to find a series of compromise solutions between small seismic horizontal displacements and small weight values.

Optimization of a conveyor transfer chute including particle flows

A common problem in the transfer chute is the unbalanced mass flow at the outlet conveyor. The objective consists in reducing the difference in curve averages of total mass in left and right part of the conveyor. Coupling Rocky DEM with modeFRONTIER enabled engineers to select the optimum design that reduced this difference to 0.2%.​

Inverse derivation of constants for the constitutive equation and fatigue model of PB-free solder joints based on experiment results, finite element simulation and virtual optimization methodology

A novel approach of deriving the constants for lead free solder creep constitutive equation and fatigue model has been proposed in this paper. In this approach, the constitutive parameters and fatigue model constants were determined retrospectively based on the test results of selected lead-free BGA packages, multi-objective optimization, and finite element modeling. ANSYS and modeFRONTIER are coupled in this methodology.
