FRAME STRUCTURE DESIGN AND FINITE ELEMENT ANALYSIS OF CORN COMBINE HARVESTER FOR HILLS AND MOUNTIANS

In view of high center gravity and poor stability traditional corn harvesters, a combine harvester frame is designed for hill mountain operations based on TRIZ theory. The supports engine mode middle rear drive, consisting front frame. tail the welded under head has reduced height increased width to allow lower better whole machine. left right longitudinal beams have different heights trafficability A 3D model established using Solidworks software incorporated with ANSYS perform finite element analysis modal It turns out that full-load bending torsion conditions, strength stiffness meet mechanical performance requirements, displays fine dynamic characteristics. According results, optimized goal light weight. While requirements are met, mass lowered by changing component thickness. After optimization, entire volume 14.27%, 14.3%, conform thus achieving lightweight optimization frame.Moreover, shows overturning angle uphill 45.3°, downhill 45.7°, slopel 40.2°.
