Abstract

Abstract

To ensure ship getting through cross current region safely and determine the limited value of lateral velocity in inland waterway, the test of remote-control self-propelled model ship was carried out in flume, the influence of lateral velocity on ship navigation was researched, the empirical formulas were presented, which reflected the influences of cross current on cross drift velocity, drift angle, the width of sailing path and drift distance, the limited values of lateral velocities in Ⅳ and Ⅴ class waterways were analyzed. Analysis result indicates that the influence extend of cross current on ship navigation decreases with the increase of bank velocity and ship size(channel class), increases with the increase of lateral velocity and the region length, and relates to driver's navigation experience and ship's initial position; in Ⅳ and Ⅴ class waterways, for restricted route, the limited values of lateral velocity in the range of one ship are 0.48, 0.58 and 0.70 m·s^-1 when the values of bank velocity are 2, 3 and 4 m·s^-1 respectively.
