Influential Factors Analysis of Racking Deformation on Large PCTC
In order to analyze the factors affecting the Racking deformation of large pure car and truck carrier(PCTC),the distribution trend of Racking deformation of a 7 000 units PCTC ship is analyzed.The influence of different lengths and widths on Racking deformation is compared by designing three different positions of stairway wall structures.Taking the main dimensions of deck beam and side frame as parameters,the influence on Racking deformation and the relationship between Racking deformation and fatigue damage are analyzed.The results show that the greatest influence on Racking deformation is the wall of the stairway,and its location is very important.The deformation value is basically linearly related to the length and width of the wall.The size of deck beam also has obvious influence on Racking deformation,but the influence of side frame is relatively small.Fatigue cumulative damage is directly related to Racking deformation.The results can be used as guidance and reference for controlling Racking deformation and improving fatigue strength of large PCTC.
