Multibody Dynamics (MBD)
DJHEC can analyze mechanical systems through multibody dynamic simulation. This type of simulation involves a group of components connected with various joints that restrict their relative motion. Some examples include an engine, a suspension system, and an excavator linkage such as the one shown below. Large systems can be difficult to model individually when the forces imposed on them are a combination of internal (inertia) and external (force or acceleration) loads. Modeling the entire system makes it possible to capture the interactions and provide useful design data in the form of forces, moments, velocities, accelerations, stress, strain, etc.
The components modeled can undergo large rotations/translations and the interaction between components can be captured. The forces between them can be plotted over time as well as their relative velocities. The bodies in the simulation can be flexible or rigid depending on the need to review stress/strain in the body.
- Models an entire mechanical system
- Provides useful joint force and component velocities
- Results can be plotted over time
- Extremely efficient runs especially with rigid bodies
- Flexible bodies can be added easily to provide stress/strain
