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.
當(dāng)主體結(jié)構(gòu)的剛度k1遠(yuǎn)遠(yuǎn)大于突出物的剛度k2,主體結(jié)構(gòu)的質(zhì)量M1遠(yuǎn)遠(yuǎn)大于突出物的質(zhì)量M2,且k1／k2與M1／M2相接近時(shí),容易發(fā)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.
研究了在橫向動載荷作用下存在軸向力的一類梁的強(qiáng)非線性振動;建立了梁振動的二階強(qiáng)非線性非自治微分方程,并對求解強(qiáng)非線性自治系統(tǒng)的能量迭代法加以改進(jìn),用于求解梁的強(qiáng)非線性非自治系統(tǒng),其方法是:由能量法得到主共振、超諧共振和次諧共振的一次近似解的表達(dá)式;引入牛頓迭代的思想和最小二乘法,得到高次近似解的表達(dá)式。
Based on the condition, the stability boundaries are obtained in the cases of subharmonic resonance and conbination resonance.
