摘要

在光学元件动力学计算模型和光线传输失调模型建立的基础上,形成了一种振动失调反射光学系统的模拟计算方法。分别通过模态实验和振动台实验对系统模型进行验证和修正。实验和模拟的结果对比表明:修正后元件动力学模型的模态参数计算结果和实验结果偏差在5%以内,修正后振动失调反射光学系统模拟计算结果与振动台测试结果偏差在17%以内,得到了可靠的振动失调反射光学系统模拟计算方法,为光学系统的抗振性能分析和减振分析奠定理论基础。

Abstract

Based on the dynamics calculation model of optical elements and the ray transmission misalignment model, a numerical calculation method was established about misaligned reflection optical system under interference vibration. Numerical calculation of system was updated and verified by the modal experiment and shaking table test. The comparison results of the experiment and calculation show that: the deviation of the single optical element’s dynamics calculation result is less than 5%, and the deviation of the basic reflection optical system’s vibration misalignment calculation result is less than 17%. The reliability of this numerical calculation method about misaligned reflection optical system under interference vibration was verified. The basis is provided for anti-vibration performance analysis and damping analysis.
