The Optimal Braking

The Optimal Braking

The aim of this analysis is to investigate the characteristics of a bicycle’s optimal braking and to analyze which are the most important elements a rider should take into account in order to achieve it Continue reading

Test bench for aerodynamic simulations

Test bench for aerodynamic simulations

The aim of the project is to realize a support system and a rotational system for a bike wheel to put inside a wind channel. Continue reading

Nodding Donkey Oil Pump

Nodding Donkey Oil Pump

Simulation of a nodding donkey pump: Analysis of pumping forces and speed and obtaining the required engine momentum. Continue reading

Leonardo Da Vinci’s self-propelled cart

Leonardo Da Vinci’s self-propelled cart

The project consists of the simulation and analysis of the Leonardo Da Vinci’s self-propelled cart. It’s part of the Da Vinci’s Atlantic Code, so that this project is a reinterpretation of Leonardo’s idea. LMS Virtual Lab software is used in order to build the virtual model: moreover some simulations are carried out to show how the car behaves, how much it turns varying the number of cams, to study the energy dissipated by the escapement systems, to determine the transmission ratio and the torsional springs’ demeanor. Continue reading

Three wheeled bicycle

Three wheeled bicycle

Dynamic analysis of a three wheeled bicycle, with a front articulated quadrilateral mechanism. The work has been developed starting from the modeling phase, passing through the implementation of a PID control system for the movement and concluding with a series of simulations in order to check the reliability of the control and to obtain an estimate of the order of magnitudes of physical variables (angles, forces, torques). Continue reading

Single sided suspension on a 70’s Vespa

Miante Alberto – albemiante@gmail.com – Degree in Mechanical Engineering INTRODUCTION The Vespa is a two-wheeled vehicle designed towards the end of the 40s; the model in the picture is a Vespa of the 70s. It has some features which differentiate … Continue reading

Analysis of a FSAE suspension system

Analysis of a FSAE suspension system

Ballotta Giacomo (giacomoballotta@gmail.com)     INTRODUCTION The vehicle presented in this project is the FSAEprototype of the University of Padua, which competed in the 2013 season of the series. Fsae is a students engineering competition where student teams from around … Continue reading

Valvetronic System

Valvetronic System

The aim of this work is the analysis of the BMW Valvetronic system. The Valvetronic system guarantees a continuous variation of valves lift and valves timing of the intake system. Thus, the Valvetronic engine no longer requires a throttle butterfly, which causes fluid dynamics losses at low speed. The obtained results are an increase of the efficiency and consequently a reduction of fuel consumption (up to 10% throughout the entire operating range) and exhaust emissions. However, the mechanism used is not so complex and represents an artful solution Continue reading

Wankel engine

Wankel engine

The Wankel engine, presented for the first time by Felix Wankel in 1957, was conceived as an alternative to the traditional Otto engine based on the crank mechanism: it uses the eccentric rotation of its rotors to create the well known thermodynamic cycle of a four-stroke engine. Continue reading
