Modeling and Optimizing IPMC Microgrippers

This project was run with the goal of optimizing IPMC (Ionic Polymer Metal Composite) fingers for deflection and force. An optimization process using the FEA model was chosen. The best way to achieve design goals without simply cutting out an IPMC finger and testing it, was to use an optimization package using modeFRONTIER and Comsol Multiphysics. 

Vehicular causation factors and conceptual design modifications to reduce aortic strain in numerically reconstructed real world nearside lateral automotive crashes

This study aims to find an effective means of substantially improving the outcome of motor vehicle crash induced aortic injuries. A DOCE study was performed on 16 different combinations of five design factors generated using a Latin Square method in modeFRONTIER 4.0. The experiment utilized FE vehicle models and the Wayne State Human Body Model.

Crash Pulse Characterization for Restraints System Performance Optimization

This study aims to develop a process for crash pulse characterization for the early phase of the product development, conducted in a sled test environment. MADYMO and modeFRONTIER coupling were used for analyzing the injury performance of occupants with all crash pulses.

Artificial neural network development for stress analysis of steel catenary risers- Sensitivity study and approximation of static stress range

This study aims to assist preliminary fatigue design of steel catenary risers and demonstrates the potential power of combining automated calculations, DoE methods and ANNs in SCR fatigue design. The numerical models were created and post-processed by means of modeFRONTIER and Orcaflex using Python.

Development of a Nanosatellite De-Orbiting System by Reliability Based Design Optimization

A 3USAT nanosatellite was used in this study to explore a beneficial orbital decay process. Objectives included maximizing the aerodynamic drag force and minimizing the de-orbiting system mass. Reliability based optimum design yields the best results as it significantly improves both system reliability and performance requirements.

Multi-objective optimization of a single component and a two component Load cell

The main aim of this project is to carry out single objective and multi-objective design optimization of single component and two component load cells. An optimization process is carried out with the integration of modeFRONTIER and ANSYS with the aim of increasing bridge output and reducing the mass.

The role of prestress and its optimization in cable domes design

Cable domes are used as lightweight, versatile forms of roofing in architecture. The role of prestress and its optimization are explored in order to increase the stability and design efficiency of cable domes. A structural optimization process is proposed using the genetic algorithm implemented in modeFRONTIER.

Petrobras Designs the P-55 platform using modeFRONTIER

In 2014 Petrobras, a state-owned publicly traded Brazilian multinational energy corporation headquartered in Rio de Janeiro, Brazil, launched their P-55 offshore platform, which was initially sized using modeFRONTIER. In order to tackle the complex problem of multiple variables, constraints and objectives, as well as a desire for a rational approach to the design process, Petrobras turned to modeFRONTIER to help them with the optimization study.

Simplified FE Modeling of Rolling Tires for the Simulation of Dynamic Forces at Hub Level

Being the support of the vehicle and providing forces necessary to control it, pneumatic tires are one of the most important components. Nevertheless, they are probably the most challenging components that have to be modeled due to both their complicated composition and the materials used in their manufacturing process. 

Optimization of Suspension Design for Commuter Motorbikes

Suspension design variables plays a key role when adapting a motorbike to different road a traffic condition. Steering torque and ratio rate should be considered for different type of maneuvre, along with acceleration at rider center of gravity when coming to comfort parameters.
