Frequency response analysis¶
Qualitative measure of a system or device in response to a stimulus used to characterize the dynamics of a system. Dynamic characterization of the transfer function response of the composition in frequency domain.
Axis positions¶
Define the position of the axis. Default is (0,0,0).
Loads¶
Open the load case container, where load cases can be defined (CTRL+K on load case to configure).
Configure selected load¶
Define and configure the load case here.
Link¶
Define at which link the load is applied.
Force/Moment¶
Define the direction of the force/moment. By entering 1 in a corresponding direction means that a force/moment is applied in this direction scaled by 1.
| Direction | Force/Moment |
|---|---|
| u | Force in axial direction |
| v | Force in transversal direction |
| w | Force in normal direction |
| ru | Torque around axial direction |
| rv | Moment around transversal direction |
| rw | Moment around normal direction |
Add link load¶
Add a new link load which then can be configured.
Add link spacer¶
Add a displacement between the master and slave interface in the link.
Add component acceleration¶
Add a component acceleration load case. For example, an acceleration of -9,81 m/s2 in w-direction defines the gravitational force to the selected component.
Add composition acceleration¶
Add a composition acceleration. The acceleration is used for the whole composition and not for a component only, as in add component acceleration. For example, an acceleration of -9,81 m/s2 in w-direction defines the gravitational force to the composition.
Hint¶
By right-clicking on the number in the first column, the load can be deleted.
Frequency range¶
Define the frequency range for the frequency response analysis.
Number of points¶
The number of points defines how many steps between the minimal and maximal frequency are taken.
