This master thesis was carried out to solve the lack of a mechanism to represent longterm accelerations in motorcycle simulators. It proposes a construction, named G-Vest, specifically designed to stimulate the somatosensory system. The G-Vest is capable of simulating acceleration effects by producing pressure variations to activate the mechanoreception and proprioception. The prototype consists of a vest actuated by electric motors, which create a force backwards. The system can be easily integrated into a motorcycle simulator, like the one at BMW Motorrad. This work carries out a research study to prove the functionality of the G-Vest. Twenty participants conducted a study in which they reproduced three accelerations up to a velocity of 50, 100 and 150 km/h and a free ride with and without the G-Vest active. The results induced by the G-Vest show that the inertial and airflow-induced forces can be represented by a surface pressure on the torso and the perception of acceleration is realistic without exciting the vestibular system. Besides, the comfort of the G-Vest and the guaranteed freedom of movement on the motorcycle are also noteworthy. This work opens up a new avenue of investigation where the G-Vest is the starting point in the representation of long-term accelerations on motorcycle simulators.
