On the new motorcycle simulator developed by the Institute of Automotive Engineering (FZD) of the Technische Universität Darmstadt, a measuring system should be incorporated with the aim of deter-mining the forces generated by the motion of therider. The objective of this thesis is to design a mount for the future simulator capable of measuringthe two main outputsof rider motion: the roll and pitch rider-induced torques. The current simulator of the department located at WIVW measures only the torque around the rolling axis and the used concept does not provide the desired performance nor precision; the solution designed in this thesis should present an improvement in regards to those features as well.In order to come up with the most suitable design, the standard product development proceeding has been followed. First, by defining the demands of the mount on a request list. Next, following an organized creative process, several concepts have been proposed. All the alternatives have been eval-uated in regards to relevant criteria and the most appropriate solution has been chosen. An exhaustive multibody model has been developed using MatLAB/Simulink with Simscape extension in order to analyze the dynamic behavior of the chosen solution under any possible scenario.Finally, a basic CAD of the system has been carried out in order to materialize the constructive solutions that will bring the concept into reality. Other constructive insights have been also treated, like the bearing selection, among others. The selected approach consists on a three-legged surface that is attached to the motion platform of the simulator and serves as a base for the mock-up attachment.The orientation of the legs define the height of two coincident rotating axes(rolling and pitching), creating a mechanism able to rotateits surfacearound a desired center of rotation.When the rotation around those axes is fixed trough meas-uring elements, the rider-induced torques measuring system is enabled. By positioning said CoR at the height of the system’s CoG, most of the measuring imprecisions that presents the current simulator are eliminated, since the greatest part of inertial forces generated by the platform motion have no longer an effect on the measuring data |
