海洋核动力平台定位系统多体动力学模型试验验证
Model test verification of the multibody dynamics of a positioning system for a marine nuclear power platform
摘要
Abstract
To verify the rationality of the multibody dynamics model of the positioning system for marine nuclear power platforms and improve the reliability of the long-term mooring of marine nuclear power platforms,this study uses the multibody dynamics method and the scaled model test method to model and verify the positioning system.First,based on the multihinge topology of the positioning system,combined with the multibody dynamics theory,the multibody dynamics simulation model of the positioning system was established.Second,a 1∶9 scale model test platform of the positioning system was built,and two typical working conditions were selected for verification.Re-sults showed that the mooring leg force calculated by the multibody dynamic model was consistent with the experi-mental results,and the average error was within 2%.The analysis of the example shows that the number of cycles of force on the mooring leg is mainly concentrated in the region of low amplitude and high mean values.The model test in this study verifies the feasibility and correctness of the proposed multibody dynamics model,which can pro-vide a reference for the evaluation of the mooring capacity of the positioning system.关键词
