Hall-Effect sensor positional transducer

This paper presents the usage of Hall-Effect sensors for the creation of a low cost, zero friction, minimally invasive precise positional sensor. Hall-Effect sensors are generally being used for revealing the speed of geared-wheels as well as the angular position of wheels having an array of magnets mounted on. In most cases the Hall-Effect sensor have only been used as threshold sensing devices for revealing the presence of magnetic field

Head Centered Approach to Washout Filter Design for Motorcycle Simulators

Many motion base simulators have been developed in the last thirty years for many different types of vehicles. In order to make a simulation more realistic, linear accelerations and angular rates are exerted on the pilot by moving the platform on which the mock-up vehicle is located. This has to be accomplished without driving the simulator out of its workspace. The software component that is in charge of this is commonly referred to as washout filter. Washout filters have been widely investigated in the past, mainly in the field of flight simulators. In this article we present a washout filter designed for a motorcycle simulator. The solution follows, as a reference point, techniques previously adopted for large aircraft simulators. However great importance is given to specific aspects of motorcycle dynamics. Sensors are used to determine the rider’s position on the motorcycle being their masses comparable. Moreover the washout location is considered on the rider’s head thus being movable. The washout filter, which is being used to drive the MORIS motorcycle simulator, located at Piaggio company headquarters in Pontedera, Italy, has been tested off-line showing good results and will soon be tested on real riders

In this article we present a washout filter designed for a motorcycle simulator. The solution is preliminary and follows, as a reference point, techniques previously adopted for large aircraft simulators. Differences between motorcycle and aircraft simulation are analyzed and a preliminary customized solution is proposed. The washout filter,which will be used to drive a motorcycle simulator, currently being built at PERCRO, has been tested off-line showing good results and will soon be tested on real riders

The MORIS Motorcycle Simulator: An Overview

Many motion based simulators have been developed in the last thirty years for many different types of vehicles. In order to make a simulation more realistic, linear accelerations and angular rates are exerted on the pilot by moving the platform on which the mock-up vehicle is located. The purpose of this article is to present a 7 DOFs (vertical, lateral and longitudinal displacements, roll, pitch and yaw angles and steer) motorcycle simulator which has been realized in Pisa, Italy, in the framework of the Esprit project by a consortium composed by industrial partners (Piaggio and Humanware from Italy and HEAD acoustics from Germany) and by academic partners (Scuola Superiore S. Anna from Italy, Halmstad University from Sweden and University of Bochum from Germany). Such project started in 1995 with the aim of developing a two-wheeled motorcycle simulator conceived as a tool for the designer to acquire data on motorcycle handling and stability at the design stage as well as to collect data about rider control behavior implications in motorcycle performances

Hall Effect Sensor-Based Linear Transducer

This paper presents a new type of transducer based on Hall effect sensors. This transducer is actually used at PERCRO as a small low cost, low displacement friction system for tracking hand position. A description of several displacement sensors as well as the Hall effect is reported. The mathematical model was tested by means of an experimental apparatus. The optimal parameters were determined on the apparatus and used for the realisation of a prototypal senso
