Analysis of moment balance in beating-up mechanism and its regulation strategies under restricted space
In order to deal with the adverse effects caused by the imbalance of inertia beating force and beating resistance of beating-up mechanism,the mechanical model of beating-up mechanism is established,and the adjustment method for the structural direction of beating-up mechanism is determined by taking the four-link beating-up mechanism as an example,and the quantitative simulation analysis is carried out under the consideration of space limitation.Comparative analysis is conducted on the effects of different adjustment schemes on driving torgue and output torque,and the motion characteristics brought about by different rod length design parameters are analyzed.The simulation results show that the inertia beating-up force can be effectively regulated by adding balancing members and changing the rod length ratio.When the beating-up force is insufficient,the beating torque is increased by about 14.5％and 3％after rotational inertia and scale adjustment respectively,and in-creased by about 17.8％after joint adjustment.When the beating-up force is too large,the torque is reduced by about 7.6％after scale adjustment.The rotational inertia and angular acceleration are the main control variables of the inertia beating force,which can be adjusted to meet the requirements of weaving process under different conditions,and provide theoretical reference for the scale and structure design of the beating-up mechanism.
