【摘要】：风力发电机组的维护,需要将维修人员及相关检修设备运送至高达百米的塔顶,进行高空作业,但如何将他们安全、高效的运送成为难题。针对这个问题,本文设计了一种风塔攀登平台,利用磁吸附力吸附于塔壁的方法,实现了沿塔壁的自由升降和携带人和物的功能。此平台的关键部件包括可变径桁架和磁吸附小车,本文主要设计了可变径桁架和磁吸附单元。运用Pro/E软件进行了桁架的数字化建模;运用ADAMS软件分析了简化后的单层可变径桁架的运动过程,研究表明其可以满足功能的要求;运用ANSYS软件对关键受力部件可变径桁架进行了静力学分析和模态分析,研究表明该桁架结构满足其强度和刚度的设计要求。运用Ansoft Maxwell软件对磁吸附单元进行了二维磁场分析,并进行了实验验证,结果表明,改进后的磁吸附单元吸附力大,可以满足设计要求。
[Abstract]:The maintenance of wind turbine generators needs to transport maintenance personnel and related maintenance equipment to the top of the tower up to 100 meters, but how to transport them safely and efficiently becomes a difficult problem. In order to solve this problem, a kind of wind tower climbing platform is designed in this paper. By using the method of magnetic adsorption force to adsorb on the tower wall, the function of lifting freely and carrying people and objects along the tower wall is realized. The key components of this platform include variable diameter truss and magnetic adsorption trolley. In this paper, variable diameter truss and magnetic adsorption element are designed. The digital modeling of truss is carried out by using Pro/E software, the movement process of single layer variable diameter truss is analyzed by ADAMS software, and the results show that it can meet the requirement of function. The static analysis and modal analysis of variable diameter truss are carried out by using ANSYS software. The results show that the truss structure meets the design requirements of strength and stiffness. The two-dimensional magnetic field analysis of the magnetic adsorption unit is carried out by using Ansoft Maxwell software, and the experimental results show that the modified magnetic adsorption unit has a large adsorption force and can meet the design requirements.
