摘要
为考察某升船机船厢防撞装置的可靠性和有效性,进行了设计船舶现场实船撞击试验。观测结果表明,以设计速度船首、船尾撞击防撞装置,船舶均被防撞梁有效地阻拦;随着撞击速度的增大,缓冲油缸的油压、活塞杆受力和行程增大,工作特性与设计基本一致;船舶线型、撞击位置对防撞梁运动、受力、缓冲时间等影响较大,设计时应予以考虑。
Anti-impact gear field test by the real ship of designed typeis conducted to evaluate the reliability and effectiveness of the anti-impact gear of one ship lift chamber.It is found that the ship＇s impacting on the anti- impact gear by the ship bow and stem with the designed speed is stopped effectively by the anti-impact beam.With the increase of the impact speed, the oil pressure of the buffer cylinder, the piston rod tension and run-length all increase, and the working characteristics of the anti-impact gear is identical with the design. At the same time, the ship lines and the impaction position are the important factors for the movement of the anti-impact beam, force, buffer time, etc., therefore, these should be considered in design of the anti-impact gear.
