| Abstract: | In order to protect sluice and the traffic safety of ships,the design of water security facilities are needed for underwater sluice.The design and calculation of arresting net are the difficult and focal point of this kind of project.Motion differential equation of ship was built with momentum principle by taking Suzhou river an example,and the length of stroke of the ship and arresting time were obtained by using numerical method,and the regularity of the length of travel and velocity of ship changing with... |
