| 摘 要： | 利用ANSYS软件建立了W12-1海洋平台的有限元模型，通过在模型识别点上施加激励得到的响应方法获得了BP神经网络的训练数据。建立了关于W12-1海洋平台的BP神经网络模型，并对其振动载荷进行了识别。识别结果表明，在对海洋平台这样的大型复杂结构进行载荷识别时，神经网络方法相对于传统载荷识别方法具有更高的识别精度。 |

| Abstract: | We make use of the software of MATLAB to compile the program of BP neural net-work. The average relative error of identification is 2.47% in the calculation example of simply- supported beam. The BP neural network model about W12-1 offshore platform is set up, the vi- bration load and optimize the number of connotative layer cells and testing points participating in load identification are identified. The identification result shows that BP neural network method gets a great advantage of traditional load identification method in the load identification of such large-complex construction as offshore platform. |
