摘要
通过试验数据拟合建立缓冲器非线性动力学模型,采用仿真分析方法,仿真考虑缓冲器非线性动力学特性的桨毂中心动特性试验。仿真结果与试验结果进行比较表明,采用缓冲器非线性动力学模型能较准确地预计桨毂中心非线性动力学特性。分析了缓冲器非线性动力学特性对桨毂中心动特性的影响。
In this paper,the nonlinear dynamic characteristic model of landing gear bumpers was built up by drawing up test data.Simulated rotor hub center dynamic characteristic test considering nonlinear dynamic characteristic of landing gear bumper used simulation analysis method.Compared simulated result with test data,demonstrated the method of considering bumper nonlinear dynamic characteristic to forecast rotor hub center dynamic characteristic is accurate.The effect of nonlinear dynamic characteristic of bumper on rotor hub center dynamic characteristic was analyzed.
