Mechanical Simulation Releases BikeSim 3.2

ANN ARBOR, Mich., January 22, 2013 - Mechanical Simulation is proud to announce the release of BikeSim 3.2 vehicle dynamics software.

One of the major new features is the capability to "linearize" the vehicle math model to support classical analysis methods often used with simpler models. A common application for this feature is to identify vibration modes of the vehicle that can cause stability and safety problems. In testing the new feature, Dr. Yukio Watanabe - chief developer of BikeSim - confirmed that BikeSim correctly captured familiar vibration modes called "weave" and "wobble." However, he also found a vibration mode that has not been described in the technical literature. After contacting well-known motorcycle researcher UK Professor Robin Sharp, Watanabe found that the vibration is a mode called "chatter" that affects MotoGP racing teams when operating at high-speed and high cornering loads. According to Watanabe, "the new LINEARIZE command is a breakthrough for detailed nonlinear simulations tools such as BikeSim. Although the vehicle is a complicated, nonlinear system, the new command can be applied multiple times during a simulated test to determine the effects of speed and other factors on motorcycle modes of vibration."

Watanabe also notes that the math models include other extensions that have been requested by customers. There are several improvements in sensor ranging and detection, more options for the tire model, more options for chain drive configuration, and more easily configured nonlinear table functions.

Dr. Michael Sayers, CEO and Chief Technology Officer at Mechanical Simulation, adds "BikeSim 3.2 includes major improvements in the simulation environment that were introduced with the recent release of our CarSim software. BikeSim 3.2 brings spectacular visualization from the driving simulator world to engineers using basic simulation to accelerate their evaluations of vehicle performance. It provides advanced controls of the playback, heads-up displays of any variables in the models, multiple simultaneous views, and libraries of vehicles and proving ground areas developed by skilled video artists."

Besides adding functions, BikeSim 3.2 includes many refinements to the user interface. As automotive engineers rely more on simulation for testing and development, many who do not have time to become experts in the details of simulation find themselves needing to work with simulation tools. Developers at Mechanical Simulation have responded by simplifying the interface for occasional users, while providing even more capabilities for the advanced users.
