Creo Mechanism Dynamics Option
Creo MDO. Motion with context.
Examine how a moving assembly responds to its operating conditions. Bring mechanism motion and force analysis into the Creo design workflow, and connect the results to a considered engineering decision.
See how it moves. Understand the forces behind it.
Creo Mechanism Dynamics Option (MDO) is an extension to Creo Parametric for investigating the motion and loading of a mechanism. It supports studies involving effects such as gravity, friction, applied forces, springs and dampers, along with supported gear and belt connections.
Define the mechanism before interpreting the animation. Connections, mass properties, drivers and loads describe how the assembly is expected to behave. A meaningful study ties those definitions to an operating case and to the measurements the engineer needs to review.

Motion: what moves, and how?
Position, velocity and acceleration describe the movement. Check the connections, driver profiles and relevant range of travel before comparing a design change.
Dynamics: what forces are involved?
Investigate the forces and torques associated with the defined motion or loading. Material mass, gravity, friction and other assumptions can influence the response.
Review: what decision follows?
Examine the time history and the mechanism together. Agree what evidence is needed for the next design decision, and what additional structural or physical verification is appropriate.
Make the study useful
Test ideas earlier. Make informed design decisions.
The value of a virtual mechanism study is the decision it helps the team make. Define the question, compare the relevant alternatives and retain the assumptions behind the result.
Which priorities matter to your project?
Choose two benefits to explore side by side. Change either selection to consider another priority.
Focus the next physical test
Use a virtual mechanism to investigate a question before committing to a prototype. Identify what the digital study can explain and what still needs physical evidence.
A more purposeful test plan.
Review changes while they are practical
Explore a changed connection, driver profile or mechanism arrangement early enough to act on the result. Keep the operating case consistent when comparing alternatives.
A reasoned next design iteration.
Investigate more than one concept
Compare alternatives against an agreed motion or loading objective. Record the tradeoffs so the team understands why a promising concept deserves further development.
A visible basis for choosing a direction.
Explain behavior to the wider team
Use motion views, graphs and relevant measures to communicate what the mechanism is doing. Relate the result to the operating scenario rather than presenting an animation without context.
A review that connects movement and evidence.
Keep analysis close to design
Work from Creo model data and revisit the study after the design changes. Shared geometry can reduce translation work, but the connections, drivers and loads still need review.
A traceable relationship between model and study.
Prepare useful downstream loads
Identify the relevant reaction or inertial loading for the next engineering task. The datasheet documents transfer to Creo Simulate; confirm the supported handoff for the proposed release and verify the receiving setup.

Creo Mechanism Dynamics Option
Review kinematic and dynamic studies, measurement outputs, advanced motion behavior and documented integration scope in PTC’s 2018 datasheet.
Confirm current release, platform, license and integration support before using this reference to specify a solution.
MDO addresses a mechanism question within a broader product-development workflow. Start with the CAD model and the required engineering evidence, then choose the capabilities that support the next task.
Creo: build the product definition.
Develop the parts and assembly relationships that describe the product, then evaluate the behavior that matters. Keep the mechanism model, its assumptions and the design revision clear as the team moves between design and investigation.
Illustrative applications connect a moving product with an operating case and a responsible engineering review.

Frame a component or subsystem mechanism around documented program conditions. Retain configuration, method and review evidence; this example implies no certification or life prediction. Mechanism studies in context What evidence must accompany the motion result?
Vehicle programs coordinate components across packaging, supplier and manufacturing constraints. Use this setting as a practical example when studying mechanism motion, applied loads and dynamic forces. Which product interface and review criteria should guide the evaluation?
Investigate a representative actuator, gear train or handling mechanism. Define the operating case and examine motion and reaction loading before deciding what to change or test. Mechanism studies in context Which connection or operating phase should the study investigate?
Explore a positioning or equipment mechanism where travel and reaction forces influence the design. Review the connections and driver profiles before using the result to guide refinement. Mechanism studies in context Which motion requirement should be assessed first?
Device teams work within defined design controls and documented review responsibilities. Use this setting as a practical example when studying mechanism motion, applied loads and dynamic forces. Which product interface and review criteria should guide the evaluation?
Before you run the study. Your MDO questions, answered.
Resolve the setup, evidence and follow-on analysis questions before evaluating a representative assembly.
What is the difference between kinematic and dynamic analysis?+
Kinematic analysis describes position, velocity and acceleration. Dynamic analysis considers forces, torques and effects such as gravity and friction. Choose the study around the question and the evidence needed for the design decision.
What should we define before running a mechanism study?+
Prepare the bodies, connections, mass properties, drivers, loads and operating conditions. Check whether those definitions represent the real mechanism, and identify the measures that the responsible engineer needs to review.
Does an animated mechanism prove that the design is acceptable?+
No. An animation helps explain motion, but the model still depends on its assumptions. Review the numerical results and operating cases, and plan appropriate structural analysis or physical verification.
Can MDO represent springs, dampers, gears and belts?+
PTC describes those capabilities in the source material. Confirm the exact supported connection types, behavior and required entitlement for the selected Creo release and your proposed mechanism.
Can results support further structural analysis?+
The datasheet documents reaction, gravity and inertial-load transfer to Creo Simulate. Confirm the supported workflow and inspect the transferred loads and receiving analysis setup; do not assume every simulation product shares an identical handoff.
How should we use the older datasheet?+
Use it to frame a capability discussion and a representative demonstration. Confirm current release, platform, licensing and integration support with TriStar rather than treating the 2018 reference as a current purchase specification.
