Determination of the Load Applied to Bale Wrapping Machine Rotary Arm and Performing of Design Optimization


Number of pages:


In this study, it was aimed to determine the optimum design for bale wrapping machine rotary arm. Determination of the force has been ensured by determining of the hydraulic motor outlet pressure acting the bale wrapping arm and verifying these values with the help of mathematical equations. It was targeted to decrease the displacement and stress values via the changing of bale wrapping arm pipe thickness (6,5,4,3 and 2 mm) that does not restrict the machine's mobility. Static constructional analyses of different arm designs have been conducted with Ansys Workbench simulation program. Maximum displacement values were determined as 2.2677, 2.9035, 3.9552, 6.0299 and 11.636 mm with 6,5,4,3 and 2 mm pipe thickness respectively. Maximum stress values were obtained as 20.196, 26.651, 36.453, 55.491 and 98.806 MPa with 6,5,4,3 and 2 mm pipe thickness respectively. It can be suggested that 3mm pipe thickness could be safely used for rotating arms. It was seen that maximum stress and displacement values decreased with the increase of pipe thickness.
