A consistent model throughout the design lifecycle
Real-time kinematic and compliance models used for hardware-in-the-loop and driver-in-the-loop simulation traditionally contained a relatively low number of degrees of freedom (DOF), often around 20. Although Reduced Order Models (ROMs) remain a valid approach for certain real-time applications, sacrificing degrees of freedom solely to achieve real-time computation is no longer always necessary.
High-fidelity Adams models already used by engineering design and development teams can now be reused for applications such as hardware-in-the-loop simulation. Reusing simulation models provides a consistent model representation that can act as a single source of truth for the system under study.
Separate toolsets for offline and online simulation no longer need to be maintained, and error-prone model conversions between tools can be avoided. This one-tool, one-model approach can save both time and cost.
Efficient tuning and optimization of dynamic systems
MSC Software designed Adams Real Time to preserve the structure and parameters of multibody dynamics (MBD) systems when they are deployed in real-time applications.
This allows elements such as hard points, joints, springs, dampers, and bushings to remain available and editable without recalibrating a new Reduced Order Model for every design change or application.
As a result, the model can represent higher-frequency characteristics in system response, while different configurations can be introduced and evaluated with shorter turnaround times.
Fidelity according to the application
The frequency characteristics of an MBD simulation determine how much detail and accuracy are required in a real-time model. In general, the higher the response frequency, the greater the model-fidelity requirement.
Adams provides capabilities for creating component and subsystem models at different fidelity levels. These versions can then be selectively deployed in real-time applications according to the purpose of the simulation.
To manage these alternatives centrally, Adams supports multiple model configurations within a single model assembly and multiple configurations within individual subsystems.
This makes it possible to maintain one model database containing configurations with different levels of fidelity, including flexible, beam-based, and rigid representations, and versions suited to specific frequency-response requirements such as handling, ride, and durability. The most appropriate model version can then be maintained and deployed for each real-time application.
