【摘要】：考慮到自升式平臺的二次彎矩載荷作為其承受載荷的重要組成部分,各船級社規(guī)范中對其均提出了考慮的要求,但僅給出了二次位移的計算方法,對于在有限元計算過程中如何將其施加到模型中并未給出明確的指導,利用ANSYS軟件的非線性求解器,考慮大位移對計算結(jié)果的影響,對各種載荷施加方法進行綜合評價。對比計算發(fā)現(xiàn)各載荷施加方法對樁腿的具體受力情況影響頗大,以彎矩的形式施加與平臺約束點的方法最為合理。證實了SACS軟件在自升式平臺P-deta載荷自動計算和施加的適用性。
[Abstract]:Considering that the secondary bending moment load of the jack-up platform is an important part of the load bearing, the requirements of the secondary moment load are considered in the codes of every classification society, but only the calculation method of the secondary displacement is given. There is no clear guidance on how to apply it to the model in the process of finite element calculation. Using the nonlinear solver of ANSYS software, considering the influence of large displacement on the calculation results, various load exerting methods are evaluated synthetically. The comparison and calculation show that the load exerting method has a great influence on the concrete force of the pile leg, and the method of applying the bending moment to the constraint point of the platform is the most reasonable. The applicability of SACS software in automatic calculation and application of P-deta load on bootstrap platform is confirmed.
