MOTORCYCLE DYNAMICS IN VIRTUAL.LAB MOTION

摘要

Multibody dynamics is an important tool for virtual prototyping of Powered Two Wheelers (PTW), where it can be very useful to analyze/predict their behavior. However, the development of the multibody model and the definition of the different simulation cases are often very time consuming. With the aim of reducing the time of the simulation process, a new set of tools called "Virtual.Lab Motorcycle" has been developed in the multi-body dynamics code LMS Virtual.Lab Motion. A graphic interface allows the user to easily create a motorcycle model. By substituting the tire/ground contact with actuators, the user can also set up a virtual test rig for ride, comfort, durability analysis and reverse load-identification. The application provides the possibility to simulate the motorcycle response both on the road and on the virtual test rig. The interface and the main structure of the application are explained here and first results are presented.
