United Dynamics Simulation Analysis of Inlet and Exhaust Valves in Ultra-High Pressure Compressor

On the basis of differential equations of valve motion of reciprocating compressors, the SIMULINK tool was employed to construct and solve the simulation model. The main optimization algorithms, which the integration process replaced by an accumulation method, solved the boundary conditions encountered during a collision. The relationship curves between the displacement of the valve and the time was simulated and plotted. The algorithm idea provides a unique method to solve the boundary problem in dynamic simulation.
