The invention provides a longitudinal rigidity controllable trolley positioning system which comprises a fixing pile, a trolley main body, a trolley advancing subsystem and a trolley pitching buffering subsystem. The fixing pile has a working state and a standby state and is used for positioning a ship body in the working state; the trolley main body is connected with the fixing pile and is mounted on the ship body; the trolley advancing subsystem is connected with the trolley body and the ship body and can adjust the distance between the trolley body and the ship body; and the trolley pitching buffering subsystem is installed on the trolley body and movably matched with the ship body. According to the longitudinal rigidity controllable trolley positioning system, the trolley body is elastically connected to the ship body in the pitching direction through the rigidity-adjustable trolley pitching buffering subsystem and one group of single-turning-point trolley advancing subsystems, sothat the rotating freedom degree and pitching return rigidity of the trolley body relative to the transverse axis of the ship body are increased, and the problem that a traditional steel pile positioning system cannot conform to pitching movement of the ship body is solved; and meanwhile, pitching bending moment borne by the trolley positioning system is transmitted and absorbed through the pitching buffer subsystem, and the effect of reducing the pitching bending moment peak value is achieved.
本发明提供了一种纵向刚度可控台车定位系统,包括固定桩,固定桩包括工作状态和备用状态,当在工作状态时用于船体的定位;台车主体连接所述固定桩并安装在所述船体上;台车行进子系统分别连接所述台车主体、船体,能够调节所述台车主体和船体之间的距离;台车纵摇缓冲子系统安装在所述台车主体上并与所述船体活动配合,本发明采用刚度可调节的台车纵摇缓冲子系统和一组单转点台车行进子系统,将台车主体在纵摇方向上弹性连接于船体,增加了台车主体相对船体横轴的旋转自由度和纵摇回复刚度,解决了传统钢桩定位系统不能顺应船体纵摇运动的问题,同时通过纵摇缓冲子系统传递和吸收台车定位系统受到的纵摇弯矩,达到减小纵摇弯矩峰值的效果。
