Inertia relief Analysis for Hoisting a CAR

Inertia relief Analysis for Hoisting a CAR

Inertia relief Analysis for Hoisting a CAR

(OP)
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,

RE: Inertia relief Analysis for Hoisting a CAR

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.
