Hydraulic System Simulation

This paper presents the fundamental approaches of modeling thermal-hydraulic component briefly. A set of lumped parameter mathematical models is developed, which are based on conservation of mass and energy. Subsequently, the connection rule for basic thermal-hydraulic components and the method to automatically generate the complete thermal-hydraulic system model are put forward. The integration methods for solving the cross-coupling thermal-hydraulic equations are also discussed for a position-controlled thermal-hydraulic system. Simulation results show the interaction between pressure and temperature. The simplified representations of thermal-hydraulic differential equations are also proposed in this paper, which can reduce simulation time. The validity of the simplified representations is judged by simulation.

Hydraulic System Simulation

A method of simulating a class of hyperbolic distributed systems without using space discretization is presented. Complex distributed systems are realized by means of subsystems of basic distributed elements. The time-delay operation forms the basis of the technique which is ideally suited to hybrid or digital computation. Using this method the system is simulated independently of its boundary conditions which may be dynamic in nature. An example of a simple hydraulic system is presented.

Simulation analysis on the hydraulic system of shearer's cutting part was established based on the research of fluid simulation technology. The hydraulic model was built using the AMESim software. By verifying the results, a new method about the rigorous analysis of holistic dynamic property of the hydraulic system is developed and a new way to design new type mining machinery and improve its capabilities is provided.
