Research And Realization Of The 3D Vehicle Control System For Aligning And Assembling Ship Subsection

As an important part of the shipbuilding process,the centering and closing of the hull sections puts forward high requirements for control accuracy and stability.In this context,the three-dimensional trolley hull centering and closing system designed and implemented in this paper is a special equipment for the centering and closing process of the hull sections.The posture adjustment of the hull sections is carried out by realizing synchronous control of multiple three-dimensional trolleys to facilitate completion.High-precision,high-stability adjustment operation process.The main work of this paper includes the following parts:The posture adjustment process of the hull segments is analyzed,and the posture models of the reference segment and the segment to be adjusted are established.By calculating the segment end face adjustment,the segment adjustment is decomposed into the movement of each three-dimensional car.Aiming at the system entry of the correspondence between the serial number and the serial number of the three-dimensional trolley,an automatic vehicle search method is designed.The control method of the synchronous movement of multiple trolleys is improved,and the fuzzy PID control optimized by the beard is adopted to simplify the parameter adjustment process and improve the control effect.According to the adjustment requirements of the centering and closing of the hull sections,the function design and realization of the control system for the centering and closing of the three-dimensional car hull are carried out.First,it briefly introduces the structural composition of the three-dimensional car hull centering and closing system,and then analyzes the function of the control system.According to the analysis,the function design of the control system is completed.The main functions include communication function,pump station management,bicycle adjustment,and train group adjustment.The necessary control functions for segmented posture adjustment actions,as well as security control,alarm clearing and other functions that help maintain the security and adaptability of the system;after the function design is completed,the system is implemented using C#language on the Visual Studio platform and packaged and released.After analyzing the test requirements for the centering and closing control system of the three-dimensional trolley hull,the control system implemented in this paper was installed on the industrial computer,and the system was adjusted and linked according to the test items.The test results verified the high adjustment accuracy of the system.And reliability.The three-dimensional car hull centering and closing control system designed and implemented in this paper,through system testing,realizes the synchronous control of multiple three-dimensional trolleys,completes the functional requirements of segmented posture adjustment,and achieves the high precision and accuracy of the segmented centering and closing process.High stability requirements.
