Challenge
General Kinematics was notified that vibration was being transmitted to neighborhood homes in the Green Bay area. Due to the unusually high water table, the massive balanced units installed in the plant were in fact transmitting vibration.
Approach
This was a unique challenge for the GK team, but to add to this issue they had to be balanced in both the empty state and the loaded state to completely reduce any vibration transmittal whatsoever. The GK units that were installed at the plant were already balanced and only putting out very small dynamic forces, unnoticeable in a normal environment.
Solution
General Kinematics had to further the balancing to make it respond to any material loading changes. The balancing had to cancel as high of a percentage as possible of the loads to eliminate any forces being put into the water table. Next, any possible forces had to be dropped to a level that could not be felt by people. Next, an air bag controlled balancing system was installed. Controlled by accelerometer output readings to a PLC, this system adjusted the pressure to and from the air bags.
Results
General Kinematics was successful in achieving fantastic results in the balancing of the units and reduced the vibration to such a level that it was no longer detected by residents in the area. To this date the system has been operating with no problems.
