以采用齿轮泵浮力驱动系统的温差能驱动垂直运动水下监测平台为研究对象,通过MatlabSimulink仿真,对各模式下的运动基本方程进行数值求解。结果表明:在设定情况下,监测平台从开始下潜至到达500 m深处约需2586 s,平均速度0.19 m/s;平台到达设定深度后开始减速下潜直到停止,该过程持续约188 s,下潜约6.16 m;而监测平台从停留位置开始上浮直到上浮到海平面约需2531 s,平均速度0.20 m/s;监测平台完成一个运动周期后最终漂浮在海面上,平台壳体最上端高出水面约3 cm。
Taking the temperature difference of the gear pump buoyancy drive system as an example, the vertical motion underwater monitoring platform is taken as the research object. The basic equations of motion in each mode are numerically solved by Matlab Simulink simulation. The results show that under the setting conditions, the monitoring platform will take about 2586 seconds to reach the depth of 500 meters from the beginning and reach an average speed of 0.19 m / s. After reaching the set depth, the platform starts to decelerate and dive to stop, and the process lasts for about 188 s and a dive of about 6.16 m. However, the monitoring platform started to float from its resting position until it reached the sea level about 2531 s at an average speed of 0.20 m / s. The monitoring platform eventually floated on the sea surface after completing one movement cycle. The top is about 3 cm above the water.
