Advanced analytical method of mouldboard plough’s design

The mouldboard plough has a complex geometry surface which determines the tillage quality and the power consumption. This paper illustrates an advanced analytical method combined with computer-aided design software in order to study the effect of the geometric parameters (α, β, q , and m ) on the 3D surface design of the cylindroidal mouldboard plough. A comparison between the cylindroidal and the cylindrical mouldboard plough was investigated for only the effect of the geometric parameters (β). This study shows that the increase of the cutting angle (α) and lifting angle (β) generates different mouldboard ploughs with a larger cutting edge and produce the uprising of the mouldboard plough body relative to the direction of the tillage, respectively, which increases the consumed energy. However, the increase of the geometric parameters ( q ) and ( m ) reduces the radius curve of the mouldboard plough, which directly affects both the inversion process of the soil and the consumed energy. The comparison between the cylindroidal and the cylindrical mouldboard plough shows that the reversion process of the soil will be done with a delay in the case of the cylindrical mouldboard plough.
