FIELD: agriculture; machine building.SUBSTANCE: invention relates to agricultural machine building, in particular, to methods of vehicles curvilinear motion trajectory determining, particularly, tractors, and can be used for experimental research of machine-tractor units (MTU) when performing field operations. Method envisages, that during tractor (1) movement along curvilinear trajectory self-adjusting disk (2) draws actual trajectory, corresponding to its kinematic center trajectory. Obtained trajectory is subjected to detailed breakdown at certain intervals (depending on obtained result required accuracy) and it is steeply marked by landmarks. Trajectory polar coordinates (distance from pole (tacheometer installation point) to each of landmarks ρand angles between line are defined using electronic tacheometer with automatic count of angles and distances using laser beam, connecting first of them with tacheometer and subsequent γ) and trajectory rectangular coordinates (each of landmark relative to pole X and Y coordinates current values), “passing” by landmarks with reflecting plate. Measurement results are displayed on the screen. Electronic tacheometer is installed with selection of its installation point with minimum distance to landmarks. Kinematic center actual trajectory is obtained according to available coordinates with very high degree of accuracy.EFFECT: method is aimed at improvement of accuracy of determining of machine-tractor unit trajectory on the field, lower labor input, time for determining coordinates of each point of curve, reduced cost of declared method.1 cl, 3 dwg |
