摘　　要：介绍了国内首次进行的无轴承旋翼桨毂中心动特性试验的过程分析。运用Lms Test.lab软件模态分析为手段,同时结合以往相关型号试验技术分析改进了无轴承旋翼桨毂中心动特性试验技术。通过改进试验方法解决了无轴承旋翼桨毂中心动特性试验的技术难题,为今后无轴承旋翼研制提供了试验技术储备,对解决无轴承旋翼直升机地面共振问题打下了良好的基础。This paper described the domestic dynamic test of bearingless rotor process in the first time. By using the Lms Test. lab software model analysis and referring to the relative model test technical analysis,improved the nonbearing rotor structure dynamic test technical. By improving the experimental method solves the technical problems of the hub center dynamic test technique for bearing less rotor structure,we provided the test technical for the coming developing nonbearing rotor structure,and would provide a good bases for solving the ground resonance problem of nonbearing rotor helicopter.
