Abstract


This thesis is based on the School of Mechanical and Electronic Xuzhou Industrial Factory project complete topic is of JURGENS wide loom transformation . This paper introduced the general situation of the loom , similar loom ; then of URGENS wide loom hydraulic main pump station renovation and planning , including picking institutional hydraulic circuit analysis and optimization , slow moving volume net hydraulic circuit , the fast network analysis and sent by the system to simplify the design of the hydraulic circuit of the hydraulic circuit . Secondly , the paper mainly to transform the design of of JURGENS wide loom off Control System , sent through the system instead of the original hydraulic servo servo motor half positive and half negative let-off system ; designed according to the performance requirements of the loom from the selection motor departure , in turn determine the matching speed controllers , worm reducer , tension sensor components ; determine the static design of the control system block diagram of the control system , separate projections of the transfer function of the controlled object , servo motor control system block diagram determined speed loop transfer function of the transfer function and the servo motor speed controller of the current loop transfer function: the dynamic design of the control system , first identified by means of a feedback control system aided design MATLAB language servo motor speed controller , and control the paper the performance of the selected controller frequency domain analysis ; most important part of the entire control system is a the tension control link , the same paper by means of a feedback control system aided design the MATLAB language design tension controller , tension control determine control tension control system links the transfer function , designed for testing the correctness of this thesis, both electronic let-off system frequency domain analysis and dynamic simulation results ; taking into account the impact of structural parameters change in the the loom work process in the thesis is divided into structural changes in average seven segment and for a pulse and step response graph drawn in each section of the structure parameters , analysis of the impact of interference on the system . Finally, the paper analyzes the advantages and disadvantages of JURGENS wide loom worm mention arm system , hydraulic mention arm JURGENS wide loom large , the paper also briefly mentioned arm hydraulic circuit design .
