IDENTIFICATION OF HYDRODYNAMIC COEFFICIENTS ON OFFSHORE PLATFORM AND PRECISION ANALYSIS OF ITS RESULTS
【摘要】 论文利用新动态模型减缩方法对海洋平台结构进行自由度减缩,利用简化后的模型对水动力系数进行反演,改善了反演模型中解的不确定性,并对载荷反演中的病态问题进行了探讨,同时给出了反演结果的评估方法,为反演中测量数据的获取提供了依据,提高了反演结果的可靠性.
【Abstract】 The degrees of freedom of the offshore platform structure are reduced by applying a new dynamic model reduction in this paper.Based on the simplified model,the hydrodynamic coefficients are identified.And the uncertainty of the solution in inverse problem is improved.The ill-conditioned problem in identification of force is subsequently discussed and the assessment method of the identification result is also presented,which provides a basis for acquiring the measurement data for identification and contributes to the improvement of reliability of the identification result.
