摘要
通过Fluent软件分析飞行型绳牵引并联机器人的气动特性,通过比较飞行型绳牵引机器人在采用4种动平台时的表面压力分布得到了动平台的最佳形式;研究了飞行型绳牵引机器人在不同攻角和速度条件下升力系数、阻力系数、俯仰力矩系数的变化规律;研究了飞行速度为17 m/s时飞行型绳牵引机器人的气流速度分布状况。研究结果可为飞行型绳牵引机器人的结构设计和运动控制提供理论依据。
Aerodynamic characteristics of the flying cable driven robot(FCDR)are analyzed through Fluent software.Firstly,the surface pressure distributions of the FCDR with four kinds of moving platforms were compared to find out the best form of moving platform;then,the change rules of lift coefficient,drag coefficient,and pitching moment coefficient were investigated at different attack angles and velocities;finally,the Mach number distribution of the FCDR at airflow velocity of 17 m/s were investigated.The results of investigation can provide theoretical basis for the following structural design and motion control of the FCDR.
