剖面探测浮标上浮运动研究

Study on Buoy with Floating Movement by Section Detection

文章提出一种新的改变剖面探测浮标浮力的结构方法,即通过液压缸的伸长和缩短改变浮标的体积进而改变浮标浮力.给出浮标的结构简图并介绍浮标的控制过程,校核液压缸的推力;用力学分析的方法推导出浮标匀速运动时的速度,并计算出浮标上浮所需要的体积;分两种状态推导出浮标从静止开始上浮直到匀速运动这段过程内的瞬时加速度以及速度方程.

This paper proposed a new kind of method to change buoyancy of buoy.The buoyancy of the buoy was changed through lengthen and shorten hydraulic cylinder.This paper was given the structure diagram of the buoy and introduced the control progress of the buoy.At the second part the thrust of cylinder was adjusted.At the third part,this paper deduced the velocity of buoy’s uniform motion by using mechanical analysis.At the last part,the equation of instantaneous acceleration and velocity starting from quiescence to uniform motion of buoy was deduced in two parts.One was the buoy getting provision volume by instance,and the other was the buoy getting provision volume gradually.
