摘　　要：高速运动状态下的直升机桨叶全场景挥舞状态分析,是直升机旋翼系统进行试验时的研究热点与难点。在直升机旋翼系统试验过程中,为准确可靠的复现桨叶在高速运动时的挥舞状态,提出一种基于CATIA参数化模型与Simulink仿真模块相结合实现桨叶在高速运行下挥舞形变仿真方法。建立全尺寸桨叶模型,利用立体视觉技术获取桨叶运动过程中标记点的三维信息,再对三维信息进行数据解算得出桨叶的挥舞量,并进行数据插值,构建桨叶挥舞状态运动三维仿真模型。仿真结果表明,构建的桨叶模型能够在满足仿真精度、实时性及可控变速的要求下真实地复现出桨叶在高速运动状态下的挥舞量变化。The analysis of the full field flaps state of helicopter blades in high-speed motion is a research hotspot and difficulty in the test of the helicopter rotor system.In the process of rotor system test,to accurately and reliably reproduce the flapping state of the blade at high speed,a flapping deformation simulation method based on CATIA parametric model and Simulink simulation module is proposed in this paper.The full-scale blade model was established,and the three-dimensional information of blade mark points was obtained by using stereo vision technology,Then the data were solved to obtain the flaps amount of blade,and the data were interpolated to construct the three-dimensional simulation model of blade flaps state motion.The simulation results show that the blade model can truly reproduce the flaps change of the blade at high speed under the requirements of simulation accuracy,real-time,and controllable speed change.
