本文拟运用解析几何圆内旋轮运动规律,探讨谱仪机构的运动原理;提出了应用低付平面机构运动键活动度计算对谱仪进行机构分析的方法,利用此方法对几种典型的直进式谱仪进行了机构分析;在分析各种直进式谱仪机构性能优劣的基础上,作者提出了一种全新的全刚性、全聚焦直进式谱仪机构,并运用理论力学中回转瞬心和机构分析中的速度矢量图解分析法,具体分析了此谱仪机构中各杆点间的速度关系。
This paper intends to analyze the movement rule of the inner circle of the geometrical circle and explore the principle of motion of the spectrometer mechanism. A method to analyze the structure of the spectrometer using the movement of the movable key of the low pay plane mechanism is proposed. By using this method, Based on analyzing the merits and demerits of all kinds of straight-ahead spectrometer, the author put forward a brand-new all-rigid and all-focusing straight-ahead spectrometer, and using theoretical mechanics The instantaneous center of rotation and the speed vector graphic analysis method in the mechanism analysis, and specifically analyzes the speed relationship among the poles in this spectrometer mechanism.
