Two dimensional consideration about Plowbody (III)

Analytical consideration of resistance force on Plowbody

Abstract

(1) Two dimensional force to Plowbody is calculated in this paper, considering about transmitted force (cf. Report II).
(2) The x, y components of force to Plowbody, W_x, W_y, will influence traction force.
Q=W_x+μW_y is included in the equation of traction force, so Q is called Plowbody resistance, say.
Q will be got by equation (3) in decimal form.
(3) As Plowbody curve is represented by simple curve or connected curve (cf. Report I), Q will be got by equation (4) or (5) respectively.
(4) By some calculation as to some Plowbody curves, Q will increase as radius of curvature at share point, Plowbody height increase or share angle decrease respectively.
(5) A design of two dimensional Plowbody curve is illustrated, and Plowbody resistance, traction force and average radius of curvature about designed curve are examined.
