Simulation of soil forces on an aerway shatter tine using discrete element method

摘要: Soil disturbances from an AerWay shatter tine was modeled using a commercial software called PFC 3D (Particle Flow Code in Three Dimensions) based on the discrete element method (DEM). The objective of this study to generate soil-tool model, calibrate and validate model with field literature data, predictions required draft vertical forces pull tine. DEM predicted validated at various depths. These are kinematics assembly according Newton's laws motion. calibrated soil had relative error 7.7% for silty-clay ball stiffness (k n /k s ) 1 x 10 4 N/m bond (! ! /! 3 Pa/m. simulated results were compared data 13.4- 31.2% within depth range 100-150 mm lower depths found have smaller error. force linearly increase until plateau around 700 N per described methodology showed good correlation between simulations. suggests that modeling is very promising simulate highly variable properties, nonlinear dynamic behaviour soil, complex phenomena tool surfaces.
