摘要
Abstract
Based on laboratory tests on the silty sand in Guangdong, we researched on the permeability, deformation and strength of the silty sand, and discussed its stress-strain relationship and parameters of Duncan model. Results caused by inadequate direct navigation performance. It was found that electric motor system largely affected the direct navigation performance of ship model. Better synchronization performance of the motor system reduced the differences between two motors on parallel circuit and improved the direct navigation performance. By changing the motors of propulsion system and the materials and fixation of balances, together with improving the mode of transmission connection, the balance rudder angle decreased by 2° ~3° compared with the original scheme. The direct navigation performance was improved, and the accuracy was guaranteed. The improvement measures could be referential for similar ship model tests.关键词
