Simulate Motion
With the dynamic simulation or the assembly environment, the intent is to build a functional
mechanism. Dynamic simulation adds to that functional mechanism the dynamic, real-world
influences of various kinds of loads to create a true kinematic chain.
Understanding Degrees of Freedom
Though both have to do with creating mechanisms, there are some critical
differences between the dynamic simulation and the assembly environment.
The most basic and important difference has to do with degrees of freedom.
By default, components in Autodesk
®
Inventor
™
Simulation have zero degrees
of freedom. Unconstrained and ungrounded components in the assembly
environment have six degrees of freedom.
In the assembly environment, you add constraints to restrict degrees of freedom.
In the dynamic simulation environment, you build joints to create degrees of
freedom.
Understanding Constraints
By default, any constraints that exist in the assembly have no effect on dynamic
simulation.
