How to use the graph of the Crash Hazard Shock Test profile in MIL-STD 810G for my simulation?

Question asked by Jeremiah Hess on May 13, 2019

I am working on a Shock Response problem for an antenna that is attached to a PTV military vehicle. It is attached via a support component (rod). If the vehicle were to strike something or be subjected to some sort of shock, I wanted to be able to simulate this. Therefore, I scoured MIL-STD 810G to find a shock profile that would mimic my case. I thought that the Crash Hazard Shock profile fell within the purview of my case.

 

For the attached plot, I noticed that only the graph is attached and not the table data. Thus, I used the log-log plot to find an approximate equation that described the curve, and then found the data points.

 

1. Is this a good strategy for going about this problem?

2. Why might the MIL-STD only have included the graph and not the underlying data points?

3. Any other sources that can be looked into to better simulate my problem?

 

Thanks!
