The Control Model Research Of Automatic Charging Device For Linear Explosive

The research content of this thesis in view of the problems exist in themanufacturing process of metal lead explosion cable，To improve the metal pipeexplosion production level have practical significance. The powder charging of slendertube is a challenge in the production of initiating explosive devices, especially forautomatic powder charging.The research object of this paper is the Automatic charging device developed byCollege of Automation of Chongqing University. Through the analysis of the operationprocess of automatic charging device, this thesis set up the control model ofAutomatic charging device, Based on this, Design a Control algorithm based onHuman-simulated intelligent to optimize the control model of Automatic chargingdevice and Through the experiments prove the control model and control algorithm ofautomatic charging device is reliable.The research contents of this paper include researching the control model ofautomatic charging device, designing control algorithm. Automatic charging devicesuse small-bore metal tube as the charge carriers, Use vertical vibration to accomplishpowder filling. Firstly, this thesis analyzed the operation process characteristics ofAutomatic charging device, researched the influence on the result of powder filling，which cause by vibration parameters and impact parameters. Ascertain the controldemand of Automatic charging device can be summed up as three control problems：Fixed value sieve powder control problem，Horizontal vibration sieve powder quantitycontrol problem, powder charge density control problem, In these three questions, thecore control problem is fixed value sieve powder control problem. Because of thequantity of sieve powder is a decisive factor to the result of powder charging. Thisthesis researched the motion characteristics of powder on sieve surface by thecharacteristics of powder accumulation and flow, discussed the relationship betweenthe density of powder filling and the parameters of shock vibration. Considering thequantity of sieve powder control problem is a variable, time-varying control problem,Dissertation design the control algorithm of Automatic charging device based onhuman-simulated intelligent. Finally, use the automatic charging device as experimentalplatform, through the sieve experiment, shock vibration experiment and powdercharging experiment to prove the control model, and the control algorithm in the paper is reliable, the results of experiment show that the control algorithm in this paper canachieve the expected control goals.
