CALCULATION OF SHIP’S ACTIVE BRAKING CHARACTERISTICS

Yevgeniy Kalinichenko

Abstract


The article considers a new calculation method for determining the ship's maneuvering elements (inertial-braking characteristics) using an alternative approach. Based on the new methodology, the procedure for calculating the inertial-braking parameters of the ship is given. Within the framework of this task, an alternative approach is considered for determining the inertial-braking characteristics of a ship. The article shows that the entire braking process is divided by speed into several elementary sections and it is assumed that in each section the work of the resistance forces and the propeller stop is equal to the work of their average valuesand. And as an alternative method for determining the characteristics of the slowed and accelerated motion of the ship and its characteristics of active braking, theorems on the change in the amount of motion and kinetic energy are used. As a result, expressions of the braking time t and the coasting time S are obtained. Using the obtained expressions, an example of calculating the length and time of the coasting with active braking in the reverse direction from full forward to "full reverse" is given
