【 摘 要 】

The paper treats Riemann's partial differential equations in the form (1), where variable μ is defined by relation (2). Corresponding boundary conditions are defined in various forms, such as boundary conditions of pressure and flow on the fixed and movable boundaries. Problem formulation is constructed in order to describe hydraulic actuator dynamics in a complete form, including its real flow and geometric characteristics. Special algorithm is generated and a corresponding computer package for simulation of the complete hydraulic actuator dynamics, including the existing wave effects, using the method of characteristics to obtain the desired problem solution. Results of computer simulation of hydraulic actuator dynamics are presented in 3-D diagrams.
