摘　　要：轮转机折页机构是制约印刷速度提高的主要因素。为了提高折页机构的运动精度,采用轨迹灵敏度分析方法,在对刀式折页机构运动学分析的基础上,建立各设计参数对折刀运动轨迹的灵敏度模型。结合实例,运用Matlab对模型求解,所得结果与实际情况相符。轨迹灵敏度分析为改进刀式折页机构设计提供了设计依据,并从理论上解释了刀式折页机构常见的勾纸现象。The fold mechanism is the main factor which limits the speed of web print. For increasing the fold mechanism＇s kinesio-accuracy, a trace sensitivities model of design parameters is established on the web print fold mechanism kinematics analysis. The results of model, calculated by Matlab, are coincided to the practical situation. Trace sensitivities analysis can supply the design foundations of modifying fold mechanism and theoretically explain the dragging-papers phenomena of fold mechanism.
