ACP ACP Inventor Nastran and Dynamic Simulation 2

Question 1

In Inventor's Dynamic Simulation, what does the Output Grapher display?

Accepted Answer

Plots of position, velocity, acceleration, and force results for joints and components over the simulation time

Answer

The Output Grapher displays time-history plots of kinematic and force results (position, velocity, acceleration, reaction forces) for joints and bodies.

Question 2

What is the role of a 'contact constraint' in Inventor Nastran?

Accepted Answer

It defines the interaction between two surfaces that may come into or separate from contact during loading

Answer

A contact constraint defines how two surfaces interact — whether they separate, slide, or bond — when loads are applied during the analysis.

Question 3

In Inventor's Dynamic Simulation environment, which load type represents the effect of Earth's gravity on all components?

Accepted Answer

Gravity

Answer

The Gravity load applies a gravitational acceleration vector to all bodies in the dynamic simulation, accounting for weight effects.

Question 4

What does a 'safety factor' result display in Inventor Nastran's linear static analysis?

Accepted Answer

The ratio of material yield strength to the calculated von Mises stress at each location

Answer

Safety factor is calculated as material yield strength divided by local von Mises stress, indicating how close each point is to yielding.

Question 5

In Inventor's Dynamic Simulation, what must be done before exporting joint reaction forces to Inventor Nastran for FEA?

Accepted Answer

Run the dynamic simulation to generate force results, then use the Export to FEA command

Answer

The simulation must be run first to calculate joint reaction forces, which are then exported as loads into Nastran using the Export to FEA workflow.
