摘要:
由于滑动导向机构与镜筒之间为间隙配合,在运动过程中会导致镜片发生不同程度偏移与偏转,因此基于柔体运动学分析理论,对不同运动姿态、不同长径比的滑动导向机构以及导向钉与镜片在导向机构中的排布位置进行运动仿真分析,得出运动姿态、长径比以及导向钉与镜片排布位置对镜片偏移与偏转的影响;结合实际变焦光学系统使用要求,设计嵌套式导向机构并进行仿真分析,验证可行性;根据以上分析结果对红外连续变焦镜头进行设计加工,镜头变焦过程成像清晰,表明此种仿真分析为红外变焦镜头结构设计研究提供一种有效方法。
Abstract:
The movement of the sliding guide mechanism causes an offset and deflection of the lens due to the clearance fit between the sliding guide mechanism and drawtube. Based on the theory of flexible body kinematics, the motion simulation of the sliding guide mechanism at different motion postures, length-diameter ratios and arrangement positions of the guide pin and lens, was analyzed, which influenced the lens offset and deflection. The nested steering mechanism was simulated and analyzed to verify the feasibility and meet the practical requirements of the zoom optical system. Accordingly, the infrared continuous zoom lens sliding guide mechanism was designed and fabricated. Subsequently, the zoom process of the lens was imaged. It was demonstrated that this simulation analysis provides an effective method to enable the structural design and research of infrared zoom lens.
