Mathematical modeling of a hydraulic hitched system of gantry tractor with high clearance used in horticulture and viticulture
Abstract
Abstract A mathematical model that allows comprehensive calculation of hydraulic hitched system (HHS) operation of a four-wheel gantry tractor with high clearance was developed in the paper. Analytical dependencies of angles, angular velocities and angular accelerations were determined, as well as the analogs of linear and angular velocities and link accelerations based on the kinematic diagram of the HHS hitch mechanism. A method for complex calculation of the HHS and a computer program using the Pascal algorithmic language were proposed on the basis of developed mathematical model. The changes in values of the driving force and re-sistance force on the hydraulic cylinder rod and the changes in fluid pressure in the hydraulic cylinder were calculated.
