In view of the complex drive system of air jet loom let-off and take-up mechanism

the virtual prototype of electronic let-off and take-up mechanism is developed with down-top design based on ZAX Tsudakoma air jet loom

and then an platform support is not only provided for studying its complex mechanical drive system

but also air jet loom digitized transformation.The control curve of servo motor rotating speed is estimated through an multinomial with time variable

and then kinematics simulation for the let-off and take-up mechanism is carried out

thus angular displacement

angular velocity and angular acceleration for warp beam and cloth roller are acquired

and from simulation results we could know that

the moving cooperate relationship of warp beam and cloth roller is correct

and it is according with controlling requirement of the let-off and take-up.
