摘要
针对"菲涅耳"光学助降装置稳定平台的要求,提出一种能够实现一个方向移动和两个方向转动的空间3自由度并联机构。在航母横摇角、纵摇角以及升沉位移已知的条件下,通过并联机构的运动学分析可以求得驱动滑块的位移方程。分析结果表明该机构适用于"菲涅耳"光学助降装置稳定平台机构。
According to the requirement of Fresnel Lens Optical Landing Aid system＇s stable platform,one type of spatial three degrees-of-freedom parallel manipulator combining two degrees rotation and one degree translation is proposed.The displacement equation of the slide block if are know the roll angle and pitching angle and the vertical displacement of carrier can be gain.The analysis results prove that the manipulator can be used as the Fresnel Lens Optical Landing Aid system＇s stable platform.
