# 水下监测平台动态特性计算模型及影响因素分析Computation Model and Analysis of Influencing Factors for Underwater Monitoring Platforms Dynamic Characteristic

Abstract:
The paper aimed at the dynamic characteristic of underwater monitoring platform, which endured drag force, normal lift along flow and buoyancy, and taken into account the influence of flow force to structures dynamic characteristic, the computational model was formulated with the finite computing method of structure vibration modal on flow field and infinitesimal method idea. The influencing factors were discussed for natural frequency of underwater monitoring platform by numerical analysis method. Natural frequency of buoy was far from the vortex release frequency by adjusting the influencing factors. This method can effectively decrease the vibration by resonance and it has important implications to design the underwater monitoring platform.
