摘要

为分析海上风力机受船舶撞击时径高比对防护装置性能的影响,采用ANSYS/LS-DYNA软件研究不同径高比Ogden、Mooney-Rivlin本构橡胶及泡沫铝防护装置抗撞性能及变形模式。结果表明：随着径高比的增大,两种本构橡胶装置最大凹陷深度变化呈现相反的趋势。当径高比为2.061时,泡沫铝装置最大凹陷深度降低60.5%,泡沫铝材料最大接触力升高28.05%,Ogden材料和Mooney-Rivlin材料橡胶防护装置最大接触力分别降低27.9%和14.5%。防护装置防护效果受局部凹陷及整体弯曲引起的塑性变形影响,随着径高比的变化,装置变形形式改变影响不同本构材料防护装置抗撞性能：当径高比小于1.5、壁厚小于3 m时,防护装置变形以局部凹陷为主;当径高比大于1.5、厚度大于5 m时,防护装置主要产生弯曲变形。

Abstract

In order to analyze the influence of the diameter-to-height ratio on the performance of the protective device when the offshore wind turbine is impacted by the ship, this paper uses ANSYS/LS-DYNA software to study the anti-collision performance and deformation mode of Ogden, Mooney-Rivlin constitutive rubber and aluminum foam protective device with different diameter-to-height ratios. The results show that with the increase of the ratio of diameter to height, the change of the maximum depression depth of the two constitutive rubber devices shows an opposite trend. When the diameter-height ratio is 2.061, the maximum depression depth of the foam aluminum device is reduced by 60.5%, the maximum contact force of the foam aluminum material is increased by 28.05%, and the maximum contact force of the Ogden material and Mooney-Rivlin material rubber protection device is reduced by 27.9% and 14.5%. The protective effect of the protective device is affected by the plastic deformation caused by local depression and overall bending. With the change of the diameter-height ratio, the change of the deformation form of the device affects the crashworthiness of the protective device with different constitutive materials. When the diameter-height ratio is less than 1.5 and the wall thickness is less than 3 m, the deformation of the protective device is mainly local depression. When the diameter-height ratio is greater than 1.5 and the thickness is greater than 5 m, the protective device mainly produces bending deformation.
