Multibody Dynamics

Multibody dynamics analysis

Software for simulation and analysis of physical properties and actions take many forms. In recent years it has become more necessary to analyze mechanical and mechatronic products as a single dynamic system, solving for the complex interactions of moving parts, and how loads and forces are distributed within the system. Software for this type of engineering is called multibody dynamic (MBD) simulation.

Understand system performance

Too often product manufacturers wait until very late in the design process to understand true system performance. Individual systems are tested against specific requirements, but full-system testing and validation comes very late. Any rework or design changes so late in the product development cycle are risky and more costly than if problems can be found and solved early in product development.

MBD software improves engineering efficiency and reduces product development by making it possible to validate system-level performance early in the design process. By evaluating and managing the complex interactions between subsystems—including motion, structures, actuation, and controls—engineering teams can optimize product designs for performance, safety, and comfort earlier.

Mix and match CAE

No matter what systems you currently have in place or if you need a replacement, we can help to assemble the specific analysis elements required for your application.

Mechatronics: For incorporating control systems into mechanical models;

Flex: Technology to correctly include a component’s flexibility even in the presence of large overall motion and complex interaction with other modeling elements. Ideal for high-speed, lightweight, precise mechanical systems.

Durability: Assess stress, strain, or life of components within mechanical systems.

Vibration: Replace expensive physical tests on shakers with virtual prototyping. Ideal for noise, vibration, and harshness (NVH) studies, and the study of forced vibration of mechanical systems using frequency domain analysis.

Bearing: Multiple modules for Bearings include Journal, Elasto-Hydrodynamic, and interfaces to various third-party, vendor-specific analysis software tools.

For the study of force elements that include the use of biomechanical human body modules, used to analyse ride comfort, handling, occupational safety or other man-machine interactions.

CAD Integration: For moving data into or out of CATIA or other CAD systems

Drivetrain: A set of modules for drivetrain simulation, including Drive Line Selection, Gear Pair, Belt, and Shaft Coupling.

Engine: A set of modules for studying the various interactions inside engines, including Hydraulic Lash Adjuster, Gas Force, Dynamic Spring, and Chain.

Flexible: For studying 3D flexible structures comprised of beam elements such as shafts, leaf springs, and lattice structures.
