Systems engineering models overview

The MCD workflow begins with systems engineering models, which are typically created in Teamcenter and imported into Mechatronics Concept Designer for use during the machine design process. There are three types of systems engineering models, which, together, document the characteristics assigned to a machine concept. The data in the models are linked so that multiple users can develop the system without affecting its integrity.

Requirement model

Documents the system's goals and specifications. For a landing gear requirements model, for example, you can specify deployment time, and joint strength.

Functional model

Documents the required tasks to achieve the goals and requirements.

This model forms the basis of collaborative design for a mechatronics system. It provides the link between the requirements and the data management of the different engineering disciplines.

Logical model

Documents how to achieve functional components.

You can break down functional models into logical blocks that can be reused in multiple designs. You can also set up discipline-specific parameters to help optimize the design.

For a landing gear logical model, for example, you can document how to achieve functional components, such as apply actuators and specify material selection.

The basic systems engineering models workflow proceeds through these three model types in sequence (requirement -> functional -> logical) before moving into the concept model stage in NX.
