Light Truck Frame Joint Stiffness Study Phase 1 Final Report

JOINT STIFFNESS TOOLBOX
Notes:
* Modify the input values (yellow) based
on your design criteria. The calculated
stiffness will be displayed in red.
* Design variables are listed in order of
influence on stiffness.
Illustration Key:
A = Side Rail
B = Crossmember Support Bracket
C = Crossmember
Design Rules:
* Make the crossmember diameter as
large as possible.
* The crossmember and side rail
thickness are the second most
important design variables.
* Click on the animation to the left of
the variables and loading conditions to
see an animation of respective shape
variable or loading condition.
* The mass calculation is based on 150
mm extension of joint members from
the side rail to interface. This is to
serve as a reference, not the absolute
value.
* The password to unprotect cells in
this spreadsheet is: steel.
