研究定向强声装置分系统转台应用在船用环境,适应船用的振动条件,可靠工作。开展转台应用于船用环境抗振研究。首先,对转台的机械台体和轴系进行结构设计。采用Ansys Workbench有限元分析软件对转台进行模态、振动、颠震、摆锤冲击仿真分析,得出转台的自然频率、应力、变形、位移、应变以及零部件的动态响应、瞬间响应、动力学分析。结果表明,转台各部件的受力均小于屈服极限值,转台的设计满足船用的试验条件,可以生产样机开展试验验证。

To study the application of sub-system turntable of directional strong sound device in marine environment,adapt to vibration condition and work reliably.The research on vibration resistance of turntable in marine environment was carried out.Firstly,the structure of the mechanical body and shafting of the turntable is designed.Then,the finite element analysis software Ansys Workbench is used to simulate the vibration,vibration,bump and pendulum impact,the natural frequency,stress,deformation,displacement and strain of the turntable,as well as the dynamic response,transient response and dynamic analysis of the components are obtained.The results show that the forces on all parts of the turntable are less than the yield limit value,the design of the turntable satisfies the test conditions of the ship,and can be tested and verified by the production of the prototype.
