This study was carried out to measure the vibrations produced by a hopper type feeder used at laying hen farms, to analyze the vibration transmissibility from the feeder to laying hen cages, to develop a mathematical model of vibration and to provide an optimum design criteria for vibration suppression of the hopper type feeder. Optimum transmissibilties were calculated for hopper type feeder of the laying hen farm tested. When the permissible maximum transmissibilty was established as 200% for vibrations produced by driving motor from hopper type feeder to laying hen cages, the designed optimum transmissibilty were 100-138% for X axis, 1-200% for Y axis, and 100-120% for Z axis. The same steel plates used for feeder will be attached as a reinforced material on locations of Y axis analyzed by vibration modes simulation. And structural modification on upper end of feeder, which transferring vibrations directly on vertical cages, will be made by using spring equipment and vibration absorbing rubber bolts. In order to absorb or isolate the vibration transfer from rail and rollers of lower end parts to hopper type feeder, the urethane coated roller manufactured in this study, will be installed for lower end of hopper type feeder.
