通过对红外导引头框架式稳定平台进行非线性分析，得出影响框架系统稳定输出的一些设计要素。转子系统的转速变化对框架稳定性响应会出现周期、拟周期及混沌振动状态。根据非线性动力学分析结果可以看出，增加系统的阻尼可以有效地抑制平台框架的刚性混沌响应。

Through the nonlinear analysis of the infrared frame seeker stabilization platform, the design elements affecting the stable output of the frame system were obtained. The response of frame stability is periodic, quasi-periodic, and chaotic depending on the speed variations of the rotor system. According to nonlinear dynamic analysis, increasing the damping of the system can effectively suppress the rigid chaotic response of the platform frame.
