无人机投放输电塔杆件的运动和受力分析

Motion and Force Analysis of Transmission Tower Rod Delivered by UAV

输电塔往往修建在交通不便的崇山峻岭中,造成修建所需的输电塔杆件运输不便。无人机投放输电塔杆件是一种快捷的运输方式,但无人机投放输电塔杆件时容易发生蹿高,严重影响无人机运输的安全性。为此,提出了一种防止无人机投放输电塔杆件时蹿高的策略。建立无人机投放输电塔杆件过程中杆件的受力和运动方程,利用MATLAB软件进行求解分析,得到各参数之间的对应关系及对投放输电塔杆件减重率的影响。结果表明,采用该策略最大减重率可以控制在20%以内。

The transmission towers are built in inconveniently located precipitous mountains,which brings inconvenience to the delivery of transmission tower rods.Unmanned aerial vehicle(UAV)is a fast and convenient means to drop the transmission tower rods,but it tends to soar when drops the transmission tower rods,which poses threats to UAV.Therefore,the paper proposes a delivery strategy preventing UAV from soaring in dropping transmission tower rods.Motion and force equations of the rods in the delivery of transmission tower rods were established and then solved by MATLAB to obtain the corresponding relationship among the parameters and the influence on weight loss rate.The results show that the maximum weight loss rate can be controlled within 20%by the strategy.
