Inertia relief Analysis for Hoisting a CAR

[Bodyinwhite]

Hi All:

Basically I have three hoisting positions to hoist a car, I have to come up with a best hoisting location( depending on the strains and displacements in the CAR).

So I am performing a Inertia relief analysis to get the reaction forces at the hoist loactions. And I am doing the SOL101 in Nastran with the hoisting loads and the reaction forces from the inertia relief analysis. Am I doing this right, If not can any one correct me.

What reaction forces are used from the inertia relief analysis to do SOL101.


Thanks in advance,

If you know the required deflection, why don't you just do an enforced displacement, and extract the reaction forces from it? That's more indicative of the real-world model anyway--a jack is an enforced-displacement on the car; not a separate force.
