Shock Requirement Interpretation 1

[DJL Eng]

I hope I've found the correct forum to post this. I was given a job assignment to evaluate a component under shock load. I am completely new to this type of analysis and was hoping to get some clarity on a note I found on a related drawing. The note says: "Maximum force transmitted during shock events are equivalent to 50G static field at upper mount".

What is meant by "static field"? I am having trouble getting in touch with the originators of the drawing. Any help is appreciated, thanks in advance!

Static g forces, i.e. 50 times gravity acceleration.

I assume that would be equivalent to an FEA analysis where the part is constrained at the mentioned location and 50g's of acceleration is applied to the body of the part. Is the direction of the acceleration intuitively obvious?

Thanks for the reply! Based on the size, shape, and mounting method the acceleration could be inferred. I'm digging through some manuals at the moment to see if I can tie a requirement to this drawing to help me make some conclusions.

Find out who added the note and get them to specify the test properly. Any test called out on our drawings has an associated test spec.

Cheers
