Identification of friction coefficients and strain-compensated Arrhenius-type constitutive model by a two-stage inverse analysis technique

A two-stage inverse analysis technique is proposed to identify the friction coefficients during hot compression test of aluminum alloy AA6N01 and its material parameters in the strain-compensated Arrhenius-type constitutive model. By means of modeFRONTIER, FEM simulation and error calculation are integrated in this study. 

Multi-Level Decoupled Optimization of Wind Turbine Structures

This study proposes a multi-level decoupled method for the design optimization of wind turbine blades. The method reduces the design space by employing a two-level optimization process: the high-level is for the entire blade, while the low-level is for sections of the blade. It is shown that the multi-level method using modeFRONTIER converges faster at the beginning of the optimization, generates more smooth design alternatives, and finds better optimum designs than its single-level counterpart.

Thermal Analysis of a Diesel Piston and Cylinder Liner using the Inverse Heat Conduction Method

This Master’s thesis developed a thermal analysis model of a diesel piston that is used in Volvo Cars engines, which enhances the possibilities to determine the complete thermal loads of the car engine and can be used as a boundary condition when performing combustion CFD-simulation. 

Multi-objective optimization of oblique turning operations

Multi-objective optimization of oblique turning operations while machining AISI H13 tool steel has been carried out in this study using the FEM method and modeFRONTIER's multi-objective genetic algorithm MOGA-II. The objective is to minimize main cutting force (force component in the cutting speed direction) and tool–chip interface temperature as both are prime contributors for the machining performance in terms of tool wear and surface integrity of the workpiece.

Influence of Body Stiffness on Vehicle Dynamics Characteristics in Passenger Cars

This study aims to analyze how vehicle dynamics are affected by local and global car body stiffness. The influence of these parameters in vehicle handling, steering and ride attributes are examined through CAE analysis tools and compared to results from physical tests. The software used for the graphical visualization and correlation of large data sets of results from the performed DOE is modeFRONTIER.

Evaluation of Railway Vehicle Car Body Fatigue Life and Durability using Multi-disciplinary Analysis Method

An integrated fatigue life and durability evaluation method based on multibody dynamics simulation (MBS) and finite element analysis for a locomotive car body is presented. A multi-disciplinary optimization algorithm is developed to handle the conflicting requirements of lightweight and good fatigue resistant car body structure designs. 

ESTECO Webinar | Optimizing rear-sear restraint system considering a divers population using Madymo and modeFRONTIER

​ESTECO and TASS International present the successful integration of their technologies to optimize a rear-seat restraint system considering a diverse population.​​​

Ship Structure Optimization Using CAD-FEM Integration

In ship structural design optimization methodologies, are not yet widely implemented in industrial applications. In this paper two different studies are presented: the optimization of a double bottom structure and the optimization of the duct structure. In both cases the challenge was to create an automatic procedure integrating CAD generation, CAD transformations and FEM analysis.

Evaluation of Grinding Repair through modeFrontier RSM and Ansys Mechanical

CHALLENGE - This study aims at evaluating the effect of grinding repairing operation based on RSM capabilites in modeFRONTIERGrind repair is a method used by SACMI to repair the surface of cast iron structural components when affected by defects like porosities or inclusions.

Study of Crash Phenomenon for Humanoid Robot

This study aims to find lighter and more robust cover solutions for robotic structures, with an ability to absorb shock energy due to strong collisions. Virtual robotic models based on the COMAN robot are chosen for the study, using the FEM model. Testing using multibody and modeFRONTIER has yielded excellent results for the chosen material.
