System Coupling Of New Workover Operating Mechanized- Integrated Modeling And Simulation

The characters of workover operation mechanizations System require not only a good structural design, but also pay more attention to the ability of responding quickly and accurately, easy loading and unloading, and facilitate shipments. The accuracy and speed of workover action is related to the load, mechanical system, hydraulic system, electrical system. A complete system can work together that highly depending on the interaction factors of many factors, which is called system coupling. The character of system coupling constrains the performance, which is also the important key factor of influencing the performance, in other words it decides whether the performance of the whole system is good or not. The relevant researches on the coupling character of the workover operating system can increase the level of automation and improve the efficiency of the whole system.In this article, the power bond graph and the modular approach is used to establish a new power bond graph model, which belongs to the new type of workover operating mechanized system. The simulation toolbox simulink of Matlab software is employed to study the new type workover mechanized system, which is mainly focus on the coupling relationships between the subsystems, such as pressure within the system, load, flow, liquid resistance, liquid capacity, mechanical moment of inertia or mass, hydraulic cylinder to start viscous friction coefficient, the linear junction compliance coefficients, the effects of the system pressure and time of responding speed causing by the variation of theses parameters. Meanwhile, the article also researches on the coupling character of inter-relationships between the subsystem within the new workover mechanized system.According to the simulation results, I got the following conclusions: The capacity of the fluid channel increases, the transition time of the system will rise; The resistance of the fluid channel increases, the system will decrease the transition time; Hydraulic cylinder to start viscous friction coefficient decreases, the transition time of the system will fall down; Mechanical parts of the moments of inertia or mass go up, the system will increase the transition time; The linear flexibility coefficient of the connections rises, the system will increase the transition time; The flow rate and velocity go up, the system will drop the transition time; Load and system pressure declines, the system will increase the transition time.
