摘　　要：针对喷气织机四连杆打纬机构对纬纱运行的影响,通过建立织机四连杆打纬机构的精确数学模型,结合MATLAB计算及绘图,分析比较了两种国产喷气织机、两种日本喷气织机的打纬运动规律及特征。指出这4种喷气织机均采用短牵手打纬,其中日本2型纬纱飞行时间最长,但纵向振动较大;国产2型传力性较好,但结构尺寸较大。As to the impact of the beating-up mechanisms with four-bar linkage mechanism on weft yarn operation,a precision mathematical model is established for the beating-up mechanisms with four-bar linkage.Comparative analysis is done to the two kinds of domestic air-jet looms and two kind of air-jet looms from Japan regarding the beating up operation and the feature.Conclusion is made that the short connecting rod can be used on the four air-jet looms yet with longer time of weft yarn travel on the air-jet looms from Japan with big vibration lengthways while good conveying performance and big size with the domestic looms.
