Effect of the design moldboard on the tillage forces

摘要: Finite element modeling FEM was used to simulate the cutting process of soil using a moldboard and investigate effect its design parameters on tillage forces. The body generated with SolidWorks software mathematical model that describes relationship between (alpha angle, beta theta gamma angle). For FEM, represented by elasto-plastic model. Whereas, carried plow bodies, corresponding each these parameters, were introduced into Abaqus as discrete rigid reference point at end moldboard. At this tip, reaction force three orthogonal components calculated. results showed an important (gamma angleγ, θ, alpha α β) have significant predicted specific force. To optimize equipment designs for energy saving. They be combined experimental concerning needed process.
