Vibration / Energy Problem with jack hammer and container

Vibration / Energy Problem with jack hammer and container

Vibration / Energy Problem with jack hammer and container

(OP)
A large container/ hopper with doors in the bottom holds a stickey material.
The container had a number of diamond shaped surround pads that are used to vibrate the stickey material out of the wagon, without getting into the container.the vibration is provided by Jackhammer devices operated by hand or other means. The containers have been pierced by the operators in some cases. Doubler plates have been mentioned.
Now my issue is this.. I have a valve for the energy or joules the Jackhammers can impact. I have applied an incremental force until I got the same amount of Energy in the container arrangement as the the jackhammer can impart in the system as a whole.
Now when I employ the doubler plate with that same level of force to get the required amount of energy in the original set up I get a significant drop the energy absorbed by the system ? Surely the thicker plate would absorbe about same energy?


Any one got any suggestions for somewhere I could read up about this stuff on impacts?
