Hydraulic Control System for a Corn Detasseler 911792

Performance specifications for a corn detasseler position control system were determined. An electrohydraulic position control system was designed and bench tested against the specifications. The bench prototype utilized three different actuators, a 2 inch diameter cylinder, a 6.4 in3 motor, and a 3.0 in3 motor. Each prototype system was tested with a basic carrier bracket load and a complete detassaling assembly load. With a supply of 10 gpm at 2000 psi, a 6.4 in3 motor met the performance requirements. With the same supply, the 2 inch diameter cylinder system was too slow and the 3.0 in3 motor system was unstable.
