Soft connections, such as clips or snaps, are recommended to be modeled with spring
elements allowing to capture fixed and released degrees of freedom. Also, fixation
stiffness can be applied to capture the local and relative stiffnesses, main
contributors to S&R issues. Variations are frequent due to assembly process,
manufacturing as well as aging of the product. Thus, with this capability a sensitivity
and diagnosis of those effects can be studied.
The Attachment Stiffness Setup panel is as shown below. Figure 1.
The Attachment Stiffness Setup panel allows you to perform
following operations -
Select Parameter - a default selection list that shows
the selected parameter. In this case, Attachment
Stiffness is the value.
Global Variation % - value entry field to provide the
parameter variation range
Select All, Unselect All, Reverse Selection - parameter
list selection options
Parameter list table - table listing the attachment
stiffnesses in the model
For Attachment Stiffness,
Stochastics workflow allows you to define
variations globally or to individual stiffness direction.
Add - to add a parameter variation study to the study
table
Update - to update an existing study parameter
Parameter Variation Study table - a table listing the
study variations created
