大型涡轮机组抗冲击性能数值研究
Numerical Research on Shock Resistance of Large-Sized Turbines
摘要
Abstract
In order to find the weak links of the ship equipment suffered attack and ensure its fighting strength, it is necessary to analyze the shock resistance of marine turbine. The three-dimensional geometrical model of the turbine was built by the ProE and the finite element (FE) mesh was built by the HyperMesh. Then the FE model is imported in the ABAQUS software and the shock resistance of the turbine was calculated in time domain based on the explicit solution. The results show that the shock responses of the bear at typical parts of the turbine are intense, and the response of the spindle of compressor is relatively complex, which should be protected. The turbine has enough security in shock assessment condition, and weak links of the shock resistance are found out mainly at lapped joint of frame, chassis under frame, the joints among the shaft bearing, gear mate and bolt.关键词
