[0046] Embodiment 1

[0047] Figure 1 A flowchart of a hydraulic support simulation calculation method based on AMESim according to an embodiment of the present disclosure is shown. Figure 1 As shown, an embodiment of the present disclosure provides a hydraulic support simulation calculation method based on AMESim, including:

[0048] S101: Based on the structure of the hydraulic support system, a hydraulic support simulation model was constructed using AMESim software.

[0049] Among them, Figure 2 As shown, the structure of the hydraulic support system is divided into a pump station supply part, a column part, a push part and a bottom lifting part according to the hydraulic support's fluid supply and the hydraulic support's column, bottom lifting and frame pulling actions. Each part includes a corresponding hydraulic support system component. The hydraulic support system components include at least one of an oil tank, a variable pump, an unloading valve, a stop valve, an accumulator, an electromagnetic reversing valve, a hydraulic cylinder, a hydraulically controlled one-way valve, a pressure sensor, a flow sensor, and a hose. The hydraulic support system components can be components related to the hydraulic support action used in coal mining sites and laboratories, for example, the oil tank is used to supply fluid to the hydraulic support, the variable pump is used to control the fluid supply flow, the hydraulic cylinder is used to control the specific action of the hydraulic support, and the pressure sensor is used to monitor the pressure of the hydraulic support system when the hydraulic support is in action.

[0050] The constructed hydraulic support simulation model includes a hydraulic support system element and a control unit. The hydraulic support system element is the above hydraulic support system element, and the control unit is used to control the above hydraulic support system element, so as to simulate the actual work of the hydraulic support system.

[0051] AMESim software can build a hydraulic support simulation model containing hydraulic support system components according to the specific structure of the hydraulic support system (including the on-site structure or the structure during laboratory tests).

[0052] In this step, the structure of the hydraulic support system is divided into the above four parts, which is convenient for simulating the hydraulic support according to the fluid supply and different actions, and the actions of the hydraulic support can be more accurately controlled according to the simulation results. For example, the logical relationship between different actions can be simulated, so as to more accurately control the action sequence of the hydraulic support such as lowering the column, lifting the bottom, pushing, and raising the column, as well as the time interval between each action.

[0053] S102: simulating the pressure and flow characteristics of the hydraulic support system using the hydraulic support simulation model.

[0054] After constructing the hydraulic support simulation model, the model can be used to simulate and predict the pressure and flow characteristics of the hydraulic support system, observe the action of each hydraulic support in the entire hydraulic support system, and control the hydraulic support more accurately based on the simulation results. For example, the hydraulic support's follow-up speed can be increased, the pressure fluctuation of the hydraulic support system can be reduced, and the safe and reliable operation of the hydraulic support can be ensured.

[0055] The AMESim-based hydraulic support simulation calculation method provided in the embodiment of the present disclosure constructs a hydraulic support simulation model by using the AMESim software based on the structure of the liquid supply part and different action parts of the hydraulic support system, and then uses the hydraulic support simulation model to simulate the pressure and flow characteristics of the hydraulic support system, so as to more accurately and reliably simulate and analyze the internal flow characteristics and pressure characteristics of the hydraulic support system, accurately control the following action of the hydraulic support, reduce the pressure fluctuation of the hydraulic support system, improve the reliability of the operation of the hydraulic support system, and thus improve the safety of coal mining; at the same time, the above-mentioned simulation calculation method is simple and convenient, and can jointly simulate different hydraulic support actions, thereby improving the simulation efficiency and simulation effect of the hydraulic support system.

[0056] In some embodiments, in step S101, based on the structure of the hydraulic support system, a hydraulic support simulation model is constructed using AMESim software, including:

[0057] S1011: simulating known parameters of each hydraulic support system component using the AMESim software;

[0058] S1012: Determine a submodel of each hydraulic support system component by using the Submodel mode in the AMEsim software;

[0059] S1013: designing simulation parameters of each hydraulic support system component in each sub-model according to actual parameters of the hydraulic support system;

[0060] S1014: Performing logical control on each of the hydraulic support system components according to the simulation parameters and the known parameters to obtain the hydraulic support simulation model.

[0061] When constructing a hydraulic support simulation model using AMESim software, first simulate the parameters of the hydraulic system components available at the coal mining site and the laboratory, that is, first simulate the known parameters of the hydraulic support system. Then, use the Submodel mode in AMEsim software and use the Premier submodel function to configure a corresponding submodel for each hydraulic system component. After that, according to the actual parameters of the hydraulic support system, the simulation parameters (parameters required for simulation) of the hydraulic support system components are designed in each submodel; finally, according to the simulation parameters and known parameters of each hydraulic support system component, the logic control of each hydraulic support system component is performed according to the simulation parameters and the known parameters, and a control unit for controlling each submodel is obtained, thereby obtaining the hydraulic support simulation model.

[0062] In this embodiment, the sub-model may include a pump station liquid supply part sub-model, a column part sub-model, a displacement part sub-model and a lifting bottom molecular model. The simulation parameters of the hydraulic support system components corresponding to the pump station liquid supply part sub-model include the output flow and pressure of the pump; the simulation parameters of the hydraulic support system components corresponding to the column part, the displacement part and the lifting bottom molecular model include at least one of the cylinder diameter and rod diameter of each hydraulic cylinder, the opening pressure of each hydraulic control one-way valve, the lift of each cylinder and the mass of each cylinder.

[0063] In steps S1011 to S1014, a more comprehensive and accurate hydraulic support simulation model can be constructed by using known parameters of hydraulic support system components and simulation parameters designed in combination with actual parameters of the hydraulic support system.

[0064] In step S1014, logical control is performed on each hydraulic support system component according to the simulation parameters and the known parameters to obtain the hydraulic support simulation model, including:

[0065] The operating parameters of the hydraulic support system are used to logically control each of the hydraulic support system components, wherein the operating parameters of the hydraulic support system include at least one of time, displacement and pressure.

[0066] For example, in the control logic of the entire hydraulic support action, the first control signal is first given to the column part, and the column part starts to perform the column lowering action. When the column is lowered to a certain height, the displacement sensor starts to receive the first displacement signal, and transmits the first displacement signal to the reversing valve of the bottom lifting part and the pushing part, and controls the hydraulic support to start the bottom lifting and pushing action. When the hydraulic support pushes the moving frame to the specified position, the second displacement signal is started to be given to the column part and the bottom lifting part, and the hydraulic support starts to raise the column and lift the bottom. Finally, after the column rises to the highest point, the displacement sensor and the pressure sensor read the third displacement signal and pressure signal of the column and transmit it to the column part. After the column part receives the third displacement signal and pressure signal, the control column lifting signal is disconnected, and the entire hydraulic support action process ends. The above control logic is simple and easy to control. The opening, closing and reversing of the reversing valve are compound controlled by the displacement of each cylinder and the pressure of each chamber.

[0067] Figure 3 The chart shows the sequence of the hydraulic support's column lowering, bottom lifting, pushing, and column raising actions and the corresponding displacement curves. Figure 3 As shown, the action sequence and displacement size of lowering the column, lifting the bottom, pushing and raising the column of the entire hydraulic support conform to the actual situation of the hydraulic support, can well reflect the on-site application of the hydraulic support, is conducive to the observation of the action of the hydraulic support when the parameters are changed, and improves the simulation effect of the hydraulic support.

[0068] It can be understood that, in this embodiment, different action parts can correspond to the same hydraulic system component. For example, the bottom lifting part and the pushing part correspond to the same reversing valve, and the switching of different bracket actions is achieved by reversing the reversing valve.

[0069] In some embodiments, after the hydraulic support simulation model is constructed in step S101, the method further includes:

[0070] S201: Utilizing the Study parameters module in the AMESim software to perform batch processing to optimize the design parameters in the hydraulic support simulation model.

[0071] After the hydraulic support simulation model is constructed, the design parameters in the model (including the above-mentioned simulation parameters and parameters used for logical control, etc.) can be continuously optimized to obtain the best design parameters.

[0072] In some embodiments, in step S102, simulating the pressure and flow characteristics of the hydraulic support system using the hydraulic support simulation model includes:

[0073] S1021: Entering a simulation mode using the Simulation mode in the AMESim software;

[0074] S1022: Simulate and predict the internal flow characteristics of the hydraulic support, and determine the fluid supply flow rate of the hydraulic support according to the fluid supply requirements of different actions of the hydraulic support.

[0075] Optionally, after entering the simulation mode and before predicting the internal flow characteristics of the hydraulic support, the method further includes:

[0076] Set the total running time and printing interval of the hydraulic support simulation model.

[0077] After entering the simulation mode, first set the total running time and printing interval of the model, and then use the constructed optimal model to perform simulation calculations to more accurately and reliably predict the internal flow characteristics of the hydraulic support, and determine the reasonable fluid supply flow rate based on the fluid supply requirements of different actions of the hydraulic support, so that the hydraulic support can perform different following actions and improve the efficiency of the hydraulic support following actions.

[0078] Furthermore, the method further comprises:

[0079] S1023: Determine the pressure characteristics of the hydraulic support according to the internal flow characteristics of the hydraulic support;

[0080] S1024: Determine the fluid supply flow rate of the hydraulic support according to the pressure characteristics and rated fluid supply of the hydraulic support.

[0081] In this step, it can be determined whether the pressure fluctuation of the hydraulic support is large based on the internal flow characteristics of the hydraulic support predicted by simulation. If the pressure fluctuation is large, a more reasonable fluid supply flow rate is determined based on the rated fluid supply to increase the following speed of the hydraulic support and reduce the pressure fluctuation of the hydraulic system.

[0082] Step S1023 and step S10244 can be applied to determine the liquid supply flow rate under the same hydraulic support action, so as to reduce the pressure fluctuation of the hydraulic support system.

[0083] The hydraulic support has many movements, and the hydraulic power of the comprehensive mining working face directly affects the driving force, speed, stability, etc. of the hydraulic support. Therefore, the above steps S1021 to S1022, and the above steps S1023 to S1024, by simulating and predicting the internal flow characteristics of the hydraulic support, can effectively analyze the various factors affecting the rapid following of the support, and also provide a basis for experiments and subsequent improvements.

[0084] In specific implementation, the pressure fluctuation of the hydraulic support system can also be simulated according to the pressure monitored by the pressure sensor, and the hydraulic support action can be simulated and predicted and controlled in combination with the flow characteristics of the hydraulic support, so as to subsequently accurately control the hydraulic support action according to the simulation control results.
