harmonic force

this paper studies chaotic motions in a nonlinear oscillatory system perturbed by external harmonic force and bounded noise excitation.

研究谐和外力与有界噪声激励联合作用下的一类非线性振子的混沌运动。

finally, the steady-state response of the nonlinear system depicted by new physical models under harmonic force is discussed.

最后还对读物理模型所代表的非线性系统在谐和外力作用下的稳态反应进行了讨论。

at the same time the system is asymmetric about its foundation, which is excited by an off center harmonic force.

因此系统关于其基础是对称的，而其基础则受到离心荷载的简谐激励。

The principal, ultraharmonic and subharmonic resonance of an elastic rotation shat with twin sides by a harmonic force is discussed, in this paper.

本文研究在简谐激励力作用下二端面弹性转轴相对转动的主共振、超谐波共振和亚谐波共振。
