摘要
本文给出了某直升机"地面共振"计算的方法和原始参数,以及该新型直升机桨毂中心动力特性试验数据处理的结果;在此基础上进行了直升机"地面共振"计算,得出计算结果,绘制稳定性曲线,进行计算结果分析,然后给出了某直升机"地面共振"计算的明确结论。最后,本文还给出了某直升机"地面共振"试验的方法和结果,"地面共振"试验的结果验证了"地面共振"的计算结论是正确的。
In this paper,the calculation method,original parameters as well as test results of the helicopter frequency response on hub center are presented.Based on those,the ground resonance calculation is performed and the results are plotted into stability curves.Through analysis of the calculation results,the definite conclusion is made out.Finally,the ground resonance test way and the results are also given out,which verify the analysis conclusion.
