A material point method based ploughing model to study the effect of asperity geometry on the ploughing behaviour of an elliptical asperity

Tribology International, 2020
A material point method (MPM)-based numerical model has been used to study the effect of asperity size and orientation relative to sliding direction on the ploughing behaviour of a rigid, ellipsoidal asperity. Based on the simulated ploughing behaviour, an analytical model has been extended to calculate the ploughing depths over the wear track and ...

A force prediction model for mouldboard ploughs incorporating the effects of soil characteristic properties, plough geometric factors and ploughing speed

Biosystems Engineering, 2007
A mathematical model that predicts the draught force acting on a mouldboard plough body is described. An important aspect of the model is that draught force is calculated using the geometric parameters of the plough body components, the ploughing speed and the physical properties of the soil.

Effects of a Plough Support Wheel During Ploughing

Journal of Agricultural Engineering Research, 1996
When the plough support wheel is in use, the quality of the ploughing and the mobility of the tractor is improved significantly. With the support wheel, the tractor power lift functions better because it foresees changes in the ploughing depth and in the field profile.
