Point Mobility scenario (Simcenter 3D NVH)

Point Mobility shows the physical response of the model to a unit force. You can plot displacement, velocity, or acceleration over force as a function of frequency. Point mobility is available when the excitation and response location and degrees of freedom are the same.

Parameters

The following table lists the parameters available for defining Point Mobility post-processing scenarios. They appear in the Parameters node of the Scenario Based Data-Visualization Navigator.

Parameter	Definition
Vibration Conversion	Lets you convert the Point Mobility response to:DisplacementVelocityAcceleration

Vibration conversion from displacement to velocity and acceleration

Normalized Conductance

The Normalized Conductance definition plots conductance as a function of frequency, to help you visualize problematic frequencies.

Normalized conductance is defined as \sqrt {REAL(velocity/force)} .
