  • 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 a V6 3.0L diesel engine under different operative conditions

    This study couples optimizer modeFRONTIER and GT-SUITE in the configuration of an engine model. The aim is to improve performance over a wide range of operating conditions including full load, part load and transient maneuvers. The choice of the final optimum has been made thanks to the MCDM tool.
