摘要:
为了补偿光学成像系统在成像过程中受自身重量、振动以及温度变化等因素引起的相位误差,设计了一种Z型薄片式柔性支撑结构用于反射镜相位补偿。建立了Z型薄片的力学模型,推导了多组柔性薄片模型下的反射镜系统平移刚度和偏转刚度表达式,根据刚度方程分析了薄片厚度及倾角对柔性支撑结构的力学影响。最后,通过有限元分析对理论模型进行了仿真验证。针对100 mm口径铝材反射镜仿真结果表明,理论推导值与仿真结果相对误差小于8%,说明了所建力学模型与刚度方程的高准确性,为柔性支撑结构的设计、力学分析以及参数优化提供了理论指导。
Abstract:
A portable Z-wafer-type flexible supporting structure was designed to compensate the optical imaging system phase error caused by the lens body weight, environment vibration, and temperature interference. The mechanical model of this optical mount was established based on its working principles. The stiffness formulas of mirror system are deduced by multiple sets of flexible sheet. Chip thickness and dip angle are analyzed based on the stiffness equation of flexible supporting structure. Finally, the theoretical model was verified using finite element analysis. The 100-mm aluminum-reflector simulation results showed that the relative difference between the theoretical derivation and simulation results was less than 8%. The construction mechanics model and stiffness equation are highly accurate and could provide theoretical guidance for the design of flexible supporting structures, mechanics analysis, and parameter optimization.
