[Kartbuilding] guidance - Cosmos Static Analysis of Chassis Frame

[Stephen Burke]

Ershad Ilahi Khan,

I will offer what advise I can on how to analyze the loads on the frame
using Cosmos. You will have to look up various tutorials on Cosmos
regarding tube frame analysis using Cosmos. I have only limited
experience using Cosmos.

The questions you will need to ask:
Is the chassis a ladder type? or space frame? or a ladder with roll cage
type?
What material is the chassis been made from? Mild Steel?
What weights are involved? What weight is the engine and wheels and driver?

If I was going analyzing a chassis, I would break it down into its
individual components. I would take just the frame itself firstly. Using
Cosmos, setup the restraints and the loads. The restraints for the frame
would be the rear axle carriers and the front king pin joints. I would
perform a static analysis on this frame firstly.

It would be extremely difficult to analyze the entire kart all together.
The separate components need to be broken down and analyzed separately.

I suggest you search for specific cosmos tutorials for frame and tube
analysis. The steering and axle components should be easy to analyze on
their own.
As for loadings and weights involved, I would not know off-hand. You
will need to obtain the weights of all components involved. Try to use
SolidWorks 3D Content Central as much as possible, as those parts will
have materials and weights contained within them.

Best of Luck,
Stephen

Same is the case with the above mentioned parts. So please help us out.
