基于并联式平台的船舶轴段定位及工作空间分析

Ship shaft segment location and working space analysis based on parallel platform

  • 摘要:
      目的  目前的轴系安装多采用手工吊装模式,安装过程需要耗费大量人力和工时,也不便于维修和调整。为提高轴系安装作业的自动化水平,设计一种特殊的六自由度并联式平台,用于实现轴系的智能安装。
      方法  建立基于传感器的观测模型,利用三边质心定位算法对轴段进行定位,计算平台与轴段接触点的位置条件,通过分析平台各种工况极限位置条件得到轴段工作空间。
      结果  据此可预估轴段安装现场工作空间的安全性,有效避免装配作业时不必要的损坏,
      结论  为工程应用提供理论指导和技术支持。

     

    Abstract:
      Objectives  The manual lifting mode is often used for the shafting installation at present, for which a lot of manpower and man hours are required to complete the installation and it is not easy to repair and adjust. In order to improve the automation level of the shafting installation, a special six-degree-of-freedom parallel motion platform is designed to realize the intelligent installation of the shafting.
      Methods  A sensor-based observation model was established to use the trilateral centroid localization algorithm to locate the shaft segment. The positional conditions of the contact point between the motion platform and the shaft segment were calculated, and the limit position conditions of various working conditions of the motion platform were analyzed to obtain the working space of the shaft segment.
      Results  In view of the above, the safety of the working space for installation of the shaft segment can be estimated, and unnecessary damage during assembly work can be effectively avoided,
      Conclusions  the study can provide theoretical guidance and technical support for engineering applications.
