基于绳牵引并联机器人悬挂支撑的旋转弹箭耦合运动风洞试验
Wind tunnel test for coupled motion of spinning projectile based on WDPR suspension support
摘要
Abstract
To address the complex coupling characteristics of multiple angular motions-comprising precession,nuta-tion,and spin,during flight of spinning projectiles,a suspension support mechanism with kinematic redundancy is pro-posed for wind tunnel testing of Spinning Projectile Models(SPMs)based on Wire-Driven Parallel Robot(WDPR)technology.For the first time,WDPR is successfully used in a closed wind tunnel for both static and dynamic wind tun-nel tests.First,the suspension support mechanism and the corresponding test model structure of the SPM are de-signed.Then,the kinematic model of the support mechanism with kinematic redundancy is established.Based on this,a wind tunnel test system for WDPR-based suspension support is developed.Finally,wind tunnel tests are con-ducted in the CG-01 high-speed wind tunnel.The test results demonstrate that the proposed suspension support sys-tem successfully replicates the multi-degree-of-freedom(multi-DOF)coupled motions of the SPM.The feasibility and effectiveness of the system for static and dynamic coupled motion tests of the SPM are validated.The wind tunnel tests involving the coupled angular motions of precession,nutation,and spin for the SPM are also realized for the first time.The dynamic signals obtained preliminarily reflect the complexity of the aerodynamic characteristics of the SPM under multi-DOF coupled motions,laying a foundation for further investigations into the aerodynamic characteristics of the SPM during coupled motion.关键词
