摘要
采用ANSYS有限元动力分析的原理、方法及过程,从滩海泥沙起动装置的结构特点及其在海上作业时受到海洋动力载荷作用的特点出发,分析了泥沙起动装置的结构动力分析体系和动力方程;研究了泥沙起动装置在波流载荷作用及其锚链约束下的动力响应特性。得到的装置动力响应结果对此装置的设计及其使用具有实际工程意义。
By use of the principle, method and process of the finite element dynamic analysis of ANSYS, structural dynamic analyzing system and dynamic equation based on structural characteristic of Sediment threshold motion equipment and ocean dynamic load acting on the equipment are studied in this paper, and analyze the dynamic response feature of the equipment under wave and current loads and restriction load caused by the anchor chain . Dynamic analysis result of the equipment given in this paper will be useful in the equipment design and practice engineering.
