When the quality and stiffness of outshoot are far larger than those of the main body, and k1/k2 approaches M1/M2, second-order resonance vibration happens.
当主体结构的刚度k1远远大于突出物的刚度k2,主体结构的质量M1远远大于突出物的质量M2,且k1／k2与M1／M2相接近时,容易发生二次共振。

The energy-iteration method for strongly non-linear autonomous system was modified to deal with strongly non-linear non-autonomous system, and the modified new method was developed, the analytic expressions of solution of primary resonance and superharmonic and subharmonic resonance.
研究了在横向动载荷作用下存在轴向力的一类梁的强非线性振动;建立了梁振动的二阶强非线性非自治微分方程,并对求解强非线性自治系统的能量迭代法加以改进,用于求解梁的强非线性非自治系统,其方法是:由能量法得到主共振、超谐共振和次谐共振的一次近似解的表达式;引入牛顿迭代的思想和最小二乘法,得到高次近似解的表达式。
Based on the condition, the stability boundaries are obtained in the cases of subharmonic resonance and conbination resonance.
利用该条件得到了次谐共振和组合共振的稳定边界。
