cosin/mbs is designed to be a fast and easy-to-use simulation tool for general multi-body mechanisms, especially suspensions and vehicle models for both ride comfort and vehicle handling maneuvers.

cosin/mbs is equipped with a general road and tire interface, allowing the combination with several standardl tire models like FTire, FETire, HTire, TMeasy, Magic Formula in several variants, and others.

cosin/mbs is an MBS software package, with special focus on full vehicles and vehicle component modeling. By using the comfortable data file format cosin/io, cosin/mbs can be easily parameterized, and combined with other computation software like Matlab to provide these parameters.

cosin/mbs comes with several sample data files both for vehicle models and simulation scenarios. The sample vehicle model data files comprise the most important suspension types both for front and rear axles. Thesel include

• five-link suspensions
• double wishbone suspensions
• several types of McPherson suspensions
• race-car suspensions
• customer-specific axles
• a ‘generic suspension model’ using a general nonlinear force element, situated between wheel and
• the ‘conceptual suspension’ approach, importing files (‘.scf-files’) that describe the full elasto-kinematic properties of a given suspension, from other vehicle dynamics simulation software.

Likewise, cosin/mbs also enables the user to define completely new suspension types in terms of a list of cosin/mbs elements.

Even with a detailed rendered 3D online animation and realistic sound simulation, cosin/mbs runs considerably faster than real-time.
