【摘要】 本文建立了单轮盘转4子弯扭耦合振动的非线性动力学模型,并应用自行开发的数值计算方法,对各向异性转子的弯扭耦合振动特性与各向同性转子进行了对比研究。研究结果表明:各向异性转子和各向同性转子的弯扭耦合振动只在弯扭耦合共振区有差别;在同等质量偏心的条件下,当各向异性转子最大弯曲刚度和各向同性转子的弯曲刚度相等时,各向异性转子上发生的弯扭耦合共振区小于各向同性的圆轴转子的弯扭耦合共振区。更多还原

【Abstract】 A dynamic nonlinear model of coupled bending and torsional vibration of single wheel disc rotor is presented in this paper. A comparison of coupled bending and torsional vibration between isotropic rotor and anisotropic one is given by a new proposed numerical algorithm. The result shows that there is only difference between them in resonance and the area in which the coupled bending and torsional resonance of anisotropic occurs is less than the one of isotropic one when the maximal bending rigidity of anisotropic rotor is equal to the one of isotropic rotor under the condition of same mass eccentricity.更多还原
