Preliminary Simulation of HADES Load Transfer

Space Constraints

Load will be transferred through an eye nut connected to the piston and inside of the cup. This presents a space problem, as the threading on the end of the piston rod has to accommodate the diaphragm, the eye nut, and some sort of retention mechanism (like a cotter pin). Some preliminary options (which can be combined) are:

...

The current one (featured in the CAD above) has a rating of 1,800 lbs. We still need to qualify main shock force, but a smaller eye nut will probably be ok, assuming it has a safety factor built into the cots product.
