The invention relates to the technical field of rope-driven parallel robot testing, in particular to a tension cable aerodynamic resistance simulation loading device and loading method in a steady-state flow field environment. The loading device comprises a first cable moving end point and a second cable moving end point, a flexible cable is arranged between the first cable moving end point and the second cable moving end point, a plurality of loading pipes are arranged on the flexible cable at intervals, and a self-adaptive elastic piece is arranged between every two adjacent loading pipes; the pulling mechanism is arranged on the loading pipe, the pulling mechanism comprises at least two stages of pulling assemblies which are arranged in a stacked mode, each stage of pulling assembly comprises a plurality of groups of pulling pieces, and the group number of the previous stage of pulling pieces is two times of the group number of the next stage of pulling pieces; and one end of the loading stay wire is connected with the pulling mechanism, and the loading stay wire penetrates through the sliding mechanism. The distance between the loading pipes is automatically adjusted through deformation of the flexible cable, so that aerodynamic loads uniformly act on the whole cable body, even if the shape of the flexible cable is changed, the stress uniformity can still be kept, and the accuracy of a simulation result is improved.

    本发明涉及绳索驱动并联机器人测试技术领域,具体涉及一种稳态流场环境下张紧索气动阻力模拟加载装置及加载方法;加载装置,包括:第一索移动端点和第二索移动端点,第一索移动端点和第二索移动端点之间设有柔性索,柔性索上间隔设有多个加载管,相邻的两个加载管之间设有自适应弹性件;拉动机构,设于加载管上,拉动机构包括至少两级拉动组件,且层叠设置,每级拉动组件包括多组拉动件,前一级拉动件的组数为后一级拉动件的组数的二倍;加载拉线,一端与拉动机构连接,加载拉线穿过滑动机构。柔性索的变形自动调节加载管间距,使得气动载荷均匀地作用在整个索体上,即使在柔性索形状发生变化时,仍能保持受力的均匀性,提高了模拟结果的准确性。
