摘要
浮动式监控装置是将主要设备放置于水上浮体之上,将监控设备通过绳索放入到水下实现水下监控,其具有成本低、使用范围广等优点。浮动式监控装置因在工作时要受到风、浪、流等自然载荷的作用,且具有横荡、纵荡、垂荡和横摇、纵摇以及艏摇6个自由度的运动形式,故平台的工作平稳性对于浮动监控平台的正常工作至关重要。通过浮动监控平台在波浪中运动的数学模型,近似计算出了浮动监控平台的横摇、纵摇及垂荡固有周期,并利用ANSYS中的AQWA模块对浮动监控平台进行了水动力学性能频域及时域的仿真分析。结果表明,设计的浮动监控平台在5级海况下能够抵抗各类自然载荷的干扰,并可靠平稳的实现水下监控。
The main equipment of floating type monitoring device is placed on the water floating body,the monitoring equipment which is put in underwater by a rope to achieve underwater monitoring,it has some advantages,such as low cost,wide use,etc.Floating type monitoring device will suffer the effect of the natural loads such as wind,wave and flow.It has the six degrees of freedom of movement which consists transverse oscillation,longitudinal oscillation,heave,roll,pitch and bow wave form,so the stability of the working platform is very important when the floating monitoring platform works.Through mathematical model of floating monitoring platform in wave motion,the roll,pitch and heave natural period of the floating control platform can be obtained by approximate calculation,then the simulation analysis of frequency domain and time domain of the hydrodynamic characteristics of the floating monitoring platform is finished using AQWA module of ANSYS.The results show that the floating monitoring platform can resist disturbance of all kinds of natural load at level 5 sea condition,and can stably and reliably achieve underwater monitoring.
