“…In addition, this study provides new ideas for research in the field of fluid control and important theoretical guidance for the development and application of related technologies. Chen et al [68] designed a circular step structure based on an open center multi-way valve in the bucket machine. As shown in Figure 4, this circular step structure can reduce the flow force below the reset spring force value, preventing the valve core from clamping.…”

As one of the important factors affecting the stability of slide valves, the analysis and research of flow force are of great significance. In recent years, more and more experts and scholars have conducted research in this field, attempting to find methods to reduce or utilize the flow force of hydraulic spool valves. Flow force includes steady-state flow force and transient flow force, with steady-state flow force having the most significant impact on spool valves. The influencing factors of flow force are complex and diverse, including the cavitation phenomenon, shape of the throttling groove, and jet angle. At present, the main ways to reduce flow force are to design the structure of the spool valve, the structure of the valve sleeve, and the flow channel of the valve body. This article mainly reviews the definition, calculation methods, influencing factors, and methods for reducing the flow force of slide valves. This provides a new approach to reducing the flow force in hydraulic spool valves.

“…The first one can be used at the initial stage of the design to deliver information that could be used as a starting point for more extensive CFD simulation. Qianpeng et al [35] used lumped parameter packages to define boundary conditions for the CFD model of a spool valve. Such implementation allowed tuning the CFD model and calculation flow forces and verifying spool clamping in specific working conditions.…”

Hydraulic valves are key components of fluid power systems. They control the flow rate and pressure in hydraulic lines, actuator motion, and direction. Valves that control flow rate or pressure can be divided into two main categories: spool-type valves, where control components are similar to the piston inside a sleeve with control orifices; and seat-type valves, in which a poppet inside a seat opens and closes the flow. Forces induced on valve components during oil flow are crucial to the valve’s operational capabilities. They can be calculated using a formula originating from the momentum conservation equation for a two-dimensional control volume. Increasing demands for flow rate and pressure control accuracy cause flow forces to be calculated much more accurately than when using the analytical formula. Therefore, computational fluid dynamics (CFD) simulations are the only effective tool for their calculation. This paper reviews the CFD approaches used for calculating flow forces inside hydraulic valves. It presents typical approaches used for evaluating flow forces inside hydraulic valves. The oldest and most common are conducted for a fixed position of valve components for defined flow conditions, which do not cover all components of flow forces. The dynamic flow forces can be calculated using more complex CFD models using fluid–structure interaction (FSI) techniques. This paper presents available FSI techniques for the simulation of transient flow forces, mainly for valves whose component position is determined by the forces occurring during oil flow.

“…Zhang et al 28 performed a cosimulation of AMEsim and Matlab platform by calling AMEsim platform using S-function interface to enhance the development of control strategies for electro-hydraulic lift systems and well validated the control accuracy of the proposed observer-sliding mode control strategy. To solve the problem of spool seizure, Chen et al 29 simultaneously used three platforms, Matlab, AMEsim and Fluent, for cosimulations and obtained the critical ow data of each oil port in the slide valve through experiments.…”

Due to the nonlinearity of the hydraulic position servo system and its model uncertainty, which makes it more difficult to establish an accurate mathematical model, while a single control algorithm can no longer meet the control accuracy and demand of the hydraulic servo system. In order to better study the position control method of hydraulic swing joint and improve the control accuracy, this paper attempts to address the position servo control problem of hydraulic swing joint by proposing a sliding mode control approach in which, based on nonlinear disturbance observers and the effectiveness of the algorithm is verified by AMESim-Matlab/Simulink co-simulation. Firstly, this paper briefly describes the three-dimensional model of hydraulic swing joint and analyzes the working principle of the position servo system of hydraulic swing joint. Secondly, the mathematical model of the hydraulic swing joint position servo system was established, the control algorithm was designed, and the stability of the control algorithm was proved using Lyapunov theory. Thirdly, combining the rich component model library of AMEsim platform and the powerful numerical computing capability of Matlab platform, the co-simulation of the two platforms is realized by creating S-Function interface in Matlab platform. Finally, the validity of the proposed sliding mode control strategy based on the nonlinear disturbance observers (NDOB-SMC) strategy is verified through experimental analysis of co-simulation, and compared with the traditional PID as well as the traditional sliding mode control (SMC) algorithm, which is found to possess superior control accuracy and practical application capability.
