摘　　要：根据双针床经编机成圈工艺对沉降片的运动要求,拟定实现机构的结构类型:采用平面六连杆机构近似实现沉降片从动件的一次停歇,后续串联另一组四杆机构近似实现第二次停歇,再串联第四组四杆机构实现沉降片的运动方向和动程大小,整体结构为平面十连杆机构。利用图解法对实现机构进行尺度综合,指出两次停歇时间的长短主要决定第一、二和三级机构中各个杆件的尺度,沉降片的动程大小主要决定第四级机构的尺度。最后举例验证设计方法的可行性。In terms of the moving requirements by the loop-forming process on a double needle bars warp knitting machine, the paper designs the structure types of the sinker： a planar six-bar linkage used to realize the follower＇s first dwell approximately, its second dwell realized approximately by connecting a four-bar linkage, the sinker bar＇s moving direction and stroke range realized by connecting the fourth four-bar linkage. The whole sinker bar mechanism is a planar ten-bar linkage. After dimensions synthesized by graphic method, it points out that the length of links in the first, second and third four-bar linkage is determined by two dwell times, and the length of the links in the fourth linkage is mainly determined by the sinker bar＇s stroke. At last, it verifies the feasibility of the design method by an example.
