  • Sensitivity analysis of urban morphology factors regarding solar energy potential of buildings in a Brazilian tropical context

    Planning the urban morphology of the built environment is a key issue in shifting to a climate adapted urban environment. This paper addresses an important threefold energy challenge of tropical cities: the major potential of harnessing solar energy as renewable resource for local electricity production and the energy-saving paradox of reducing the undesirable solar heat gains in buildings while providing satisfactory levels of daylight. It aims at measuring the effect size of urban form factors regarding these energy goals.

  • Energy Consumption Minimization in Railway System

    The optimization of train movements could make the railway system even less impacting on the environment by reducing energy consumption and CO2 emissions. Only in a limited number of cases train drivers are assisted by the so called Driver Advisory System which suggests energy-efficient speed profiles. The present study aims at minimizing energy consumption in both the planning phase, where train timetables are defined, and operational phase in which traffic may be perturbed by unexpected events.

  • Vehicle steering pull - from product development to manufacturing

    The objective of this paper is to propose a novel method to evaluate the impact of dimensional variations on vehicle steering pull. The proposed method combines Monte Carlo simulation to validate the dimensional tolerances, a multibody software to simulate initial data and modeFRONTIER to create a polynomial response surface and simulate the  Vehicle Residual Aligning Torque (VRAT) distribution curve, final directional vehicle trend, and factors influence on VRAT.

  • MULTI-OBJECTIVE OPTIMIZATION OF VEHICLE OCCUPANT RESTRAINT SYSTEM BY USING EVOLUTIONARY ALGORITHM WITH RESPONSE SURFACE MODEL

    This research reports a vehicle occupant restraint system design by using evolutionary multi-objective optimization with response surface model. The vehicle occupant restraint systems are composed of restraint equipment, such as an airbag, a seat belt, and a knee bolster. The optimization aims to improve the safety of the system by evaluating some indexes based on safety regulations.

  • Flexibility analysis and determination of elastic deformations for robot manipulator

    This paper presents the flexibility and kineto-elasto dynamic analysis of a robot manipulator. The aim is to produce a trajectory that will improve the motion time and the trajectory tracking of a standard industrial machine whether it is applied to the machine through a simplified controller or a more complex controller. MATLAB and modeFRONTIER are coupled in this methodology.

  • Optimization study of occupant restraint system concerning variations in occupant size and crash severity

    The objective of this study is to build a framework for occupant restraint system optimization and to study the interaction between occupant and restraint system. A front seat passenger side restraint system model was built and parameterized, including the seat position. A genetic algorithm was used to explore potential optimal configurations for 5 dummies and 2 crash severities.
