GT-SUITE Node Integration with modeFRONTIER | Tutorial

In this brochure, a example study of exhaust muffler back pressure and acoustic optimization is explained step by step. The objective is to minimize the back pressure at the highest speed (highest flow) while limiting the noise level to a maximum of 105 dB. 

Computerized Crash Reconstruction of Real World Crashes Using Optimization Methodology

In this case study, the researchers modify the parametric methodology to include an optimization scheme to derive an optimal solution for the reconstruction problem in a given range of unknown parameters. Results of the simulations showed that the optimal solution correctly predicted both the occupant-vehicle contacts and the injuries sustained during the crash. 

Simultaneous Estimation of Multiple Thermal Parameters of Large-Format Laminated Lithium-Ion Batteries

Lithium-ion batteries have proven higher energy density and longer life cycles than secondary batteries, yet HEV/EV manufacturers are held back due to thermal limitations. This paper presents a coupled experimental/computational method to simultaneously determine multiple thermal parameters of large laminated lithium-ion batteries. 

Design strategy for improving the energy efficiency in series hydraulic-electric synergy system

Current vehicle hybrid/electric systems present limitations due to poor regeneration energy savings. The Series Hydraulic/Electric Synergy System (SHESS) is potentially a valid option for improving the overall energy efficiency of HEVs. However, the highly complex nature of this mechatronic system requires considerable design effort to simultaneously maintain reliability, contain maintenance costs and effectively avoid energy loss.

Understanding Real World Variations to Optimize New Generation Welding Processes

Based on the objectives of the Remote Laser Welding (RLW) Navigator project, partners aim at building an innovative joining technology platform for the automotive industry by combining a universal simulation engine and the manufacturing system design information (CAD/CAM) with statistical analysis, variation simulation, optimization and control tools. 

Multi-objective Optimization of Automotive Assembly Line Configurations

The early-stage design of automotive assembly lines is a critical multi-objective task. The design process is typically carried out in industry by continuous iterations between the process design department and the simulation and systems engineering department. 

Investigation About the Warm Deep Drawing of Mg Alloys Using Metamodels

Lower fuel consumption and limited emissions are one of the main concerns of the automotive sector and can be achieved by vehicle lightweighting, i.e. adopting alloys with lower density and higher strength. Magnesium alloy is among the lightest materials, but has limited formability at room temperature. 

Integration of modeFRONTIER and VI-grade Software for Efficient Multi-Objective Optimization in Multibody Systems Design

Each company department has been traditionally performing single-discipline simulations on a single vehicle model in function of their specific goals, which are often conflicting. A more integrated approach was required to achieve all objectives at once without prejudicing any of them. 

modeFRONTIER as a Design Optimization Educational Tool

This presentation shows how the course is structured and how to guide students to gain both theoretical knowledge on optimization-based design and acquire some practical experience using state-of-the-art optimization tools such as modeFRONTIER.

Optimisation in Development Phase of Vehicles Related to Total Cost of Ownership

The AeroEfficient technology approach adopted by Bombardier and the multi-disciplinary optimization capabilities in modeFRONTIER takes into account constraints deriving from crash safety, structure, industrial design and ergonomic limits of the cabin to reduce aerodynamic drag. However, the most drag-efficient engineering concept presents weight concerns and high maintenance costs.
