Abstract: Aiming at the changes of main shaft loading that comes from the beating-up mechanism in loom,the 3D model of beating-up mechanism was established based on Pro/E, mechanism module was used to make dynamic simulation for beating-up mechanism, four-bar beating-up mechanism in air-jet loom and conjugate CAM beating-up mechanism in rapier loom were used as an example,the qualitative and quantitative methods were used,the changes and distributions of equivalent moment of inertia on main shaft for every component in beating-up mechanism were contrasted. The resistance that inertia of sley system can overcome and its changes were analyzed. The results indicate that the ratio of equivalent moment of inertia on main shaft between sley system and beating-up system is 75%. The best beating-up range and the range of resistance that inertia beating-up can overcome for two different looms are gotten, they provide theory basis for design the structure parametes of beating-up mechanism reasonablely.

Key words: beating-up mechanism;sley system;equivalent moment of inertia;inertial load
