Development and Application of Hull LocRes Local Vibration Software

通过对船体局部结构固有频率的计算方法研究,选定以相当法为内核解析算法,基于C#.net平台开发出了HullLoc Res船体局部振动软件,实现船体局部结构固有频率的快速计算,使设计机构具备亚临界法识别共振风险的能力,相比于有限元法,该方法可提高设计效率,同时,以实际项目计算结果与Loc Vibs以及有限元软件的计算结果进行对比,从理论计算对比上验证了工程适用性。

Through the research on the calculation method of natural frequency for the local structure of the hull,the equivalent method is selected as the kernel analytical algorithm.The Hull Loc Res local vibration software is developed based on the C#.net platform,which can realize the rapid calculation of the natural frequency of the hull local structure,so that the design organization has the ability to identify the resonance risk with the subcritical method.Compared with the finite element method,this method can improve the design efficiency.In addition,the engineering applicability of the software is verified by comparing the calculation results of the actual project with the calculation results of LocVibs and finite element software.
