METHOD FOR DETERMINING KINEMATIC MOTION PARAMETERS OF ROWING MECHANICAL SYSTEM BOAT-ROWER-PADDLES AND FORCES ON ITS ELEMENTS Russian patent published in 2017 - IPC G01C23/00 

FIELD: measuring equipment.

SUBSTANCE: direct acceleration and speed measurements of the boat, along its longitudinal axis, and of the paddle rotation angle in the swivel around the vertical axis are carried out during the implementation of the proposed method. The angular velocity of the paddle rotation is also measured in the swivel around the vertical axis, and the angular acceleration of the paddle rotation is calculated on the basis of the obtained values. The rower movement along the longitudinal axis of the boat is measured, its acceleration is calculated on the basis of the obtained values. Next, the hydrodynamic resistance force to the boat movement, the inertial force that arises during the forward movement of the boat and the rower, and the forward and rotational movement of the paddle, the paddle inertia force moment arising during its rotation, and the forward movement of the boat, are calculated by using the obtained values of the measured values. The forces are determined, that are applied to the paddle handle, to the swivel, to the paddle blade and the substrate.

EFFECT: improving the measurement accuracy of forces, defined by the mechanical rowing system elements, reducing the time of the prelaunch system in the training process.
