Description

Technical Field

[0001] The present application relates to the field of maglev trains, and in particular to a method, system, device and readable storage medium for determining a torque point of a maglev train. Background Art

[0002] A high-speed maglev train vibration test system effectively simulates the dynamic characteristics of a high-speed maglev train under no-traction conditions. Actuators are the core equipment for achieving attitude changes and train vibration in no-traction conditions. Simulating the impact of aerodynamic loads on the train's operating attitude and vibration characteristics is also accomplished through mechanical loading with finite actuators. Aerodynamic loads are primarily derived through numerical simulation. The actuator's loading parameters for aerodynamic loads include six key parameters: aerodynamic drag, lift, lateral force, overturning moment, yaw moment, and pitching moment. The magnitude of these three moments is closely related to the location of the moment extraction point in the numerical simulation. An improper moment extraction point can result in excessively long lever arms and a sharp increase in torque. When decoupled to the actuator's location, the value can exceed the maximum allowable actuator force. However, there is currently no method for determining the optimal moment extraction point location.

[0039] The core of this application is to provide a method, system, device and readable storage medium for determining the torque point of a maglev train, which can ensure that when the actuator truly reproduces the operating state of the maglev train under the action of aerodynamic load, the actuating force range of each actuator will not have a large difference, and when the numerical simulation calculation results are decoupled to the position of the actuator, they will not exceed the allowable value of the actuator.

[0040] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] Please refer to Figure 1 , Figure 1 This is a flowchart of the steps of a method for determining a torque point of a maglev train provided in this application. The method for determining a torque point of a maglev train includes:

[0042] S101: Obtaining correlations between various loading parameters in numerical simulation calculations and various moment points on the maglev train, where the loading parameters include overturning moment, yaw moment, and pitching moment;

[0043] Specifically, the location of the torque point on the maglev train can refer to Figure 2 As shown, but not limited to Figure 2As shown, the moment point can be selected on the surface of the maglev train along any position of the vehicle body length (X direction), width (Y direction) and height (Z direction). Considering the complex external structure of the maglev train, the direct conversion of the moment magnitude between different moment points can not be realized by the simple relationship of moment and lever, therefore it is necessary to first build the correlation relationship between each loading parameter and the moment point in the numerical simulation calculation, the loading parameters include but are not limited to overturning moment, yaw moment, pitching moment, aerodynamic drag, lift and lateral force etc. The correlation relationship here specifically includes the optimal value range of each loading parameter at each moment point, such as the optimal value range of the overturning moment corresponding to moment point 7, using the corresponding relationship of each moment point and the optimal value range of each loading parameter as the correlation relationship between this moment point and the loading parameter, a database or data table can be built according to the correlation relationship of each moment point and the loading parameter, for subsequent query.

[0044] Among them, the optimal value range of each loading parameter can be determined according to the actuator parameters, dynamic characteristics and control performance.

[0045] S102: Determine the placement position and number of actuators;

[0046] As an optional embodiment, the process of determining the placement position of the actuator includes:

[0047] The position where the load-bearing capacity of the maglev train body is greater than a preset value is used as the layout position of the actuator.

[0048] As an optional embodiment, the process of determining the placement position of the actuator further includes:

[0049] The position where the body load-bearing capacity of the maglev train is greater than the preset value is obtained through structural strength simulation calculation.

[0050] As an optional embodiment, the process of determining the number of actuators to be deployed includes:

[0051] The number of actuators to be installed is determined based on the operating conditions of the maglev train and the allowable force of the actuators.

[0052] Specifically, the maximum force effect of the actuator can reach 7 tons, and the numerical simulation calculation results also confirm that the maximum aerodynamic force that needs to be loaded can reach more than 10KN. Therefore, the actuator cannot be simply placed at random. Once placed in a position where the vehicle body structure strength is weak, it may result in excessive loading and damage to the vehicle body during the experiment. Therefore, this embodiment obtains a position with a stronger vehicle body load-bearing capacity through structural strength simulation calculation, that is, a position where the vehicle body load-bearing capacity is greater than a preset value, as the placement position of the actuator. At the same time, considering that the number of actuators needs to be estimated based on the numerical simulation calculation results of different operating conditions, the operating conditions include but are not limited to open line intersection conditions, tunnel passing conditions, crosswind influence conditions, etc., and combined with the allowable value of the actuator's actuation force, it is determined how many actuators are needed to meet the reasonable distribution of aerodynamic values. The placement position and number of actuators can refer to Figure 3 shown.

[0053] S103: Based on the deployment position, deployment quantity, and associated relationships, an equivalent relationship between the loading moment at the actuator's action point and the overturning moment, yaw moment, and pitching moment is established;

[0054] Specifically, considering that numerical simulation results cannot be directly applied to the high-speed magnetic levitation vibration test platform, they need to be decoupled to the actuator location and then loaded onto the vehicle body via the actuator before experimental research can be carried out. Based on this, this step establishes an equivalent relationship between the loading torque at the actuator's point of application and the aerodynamic numerical simulation results (including overturning moment, yaw moment, and pitching moment). The main purpose of this step is to establish a relationship between the moment arm closely related to the moment point and the numerical simulation results.

[0055] S104: Determine adjustment parameters of a target moment point using an equivalent relationship and a correlation relationship, where the target moment point is any moment point;

[0056] S105: Adjust the position of the target moment point based on the adjustment parameters to obtain the optimal moment point.

[0057] As an optional embodiment, the process of determining the adjustment parameters of the target moment point using the equivalent relationship and the correlation relationship includes:

[0058] Determine the control parameters of the target moment point based on the equivalent relationship, the control parameters including the force arm of the actuator;

[0059] Based on the association relationship, the control parameters are adjusted until the force of the actuator meets the preset conditions, and the current control parameters are used as the adjustment parameters of the target moment point.

[0060] Specifically, after determining the equivalent relationship and the correlation relationship, the parameters can be adjusted according to the selected target moment point to obtain the optimal moment point. Taking the overturning moment as an example, the equivalent relationship between the overturning moment and the loading moment of the action point is (FY1-FY2)×H+FZ1×L1+FZ2×L2=Mx, where FY1 is the force value of the actuator in the lateral direction, FY2 is the force value of the actuator in the lateral direction, H is the lever arm of FY1 and FY2, FZ1 is the force value of the actuator in the vertical direction, L1 is the lever arm of FZ1, FZ2 is the force value of the actuator in the vertical direction, and L2 is the lever arm of FZ2.

[0061] Reference Figure 4 As shown, Figure 4 is a schematic diagram of the equivalent relationship corresponding to the overturning moment. According to the above equivalent relationship, the main control parameters for controlling the torque point include H, L1, and L2. Based on the correlation relationship obtained in S101, the aerodynamic drag, lift, lateral force, pitching moment, overturning moment, and yaw moment corresponding to the target torque point can be directly obtained. Since FZ1+FZ2 equals lift and FY1+FY2 equals lateral force, the values ​​of L2, L1, and H are continuously adjusted according to the above equivalent relationship until preset conditions are met to obtain a relatively optimized actuator force value. The preset conditions may include that the parameters such as FY1, FY2, FZ1, and FZ2 do not differ by more than 10 times in the actuation range, and the actuation force value does not exceed the allowable actuation force value. At this time, the current L2, L1, and H are used as adjustment parameters. Based on the position of the target torque point with these adjustment parameters, the optimal torque point position can be determined.

[0062] It is understandable that the above only uses the overturning moment as an example, and the processing solutions for the yaw moment and the pitching moment are similar.

[0063] It can be seen that the method for determining the torque point of a maglev train provided in this embodiment first obtains the correlation between each loading parameter in the numerical simulation calculation and each torque point on the maglev train, and establishes an equivalent relationship between the loading torque of the actuator's action point and the overturning moment, yaw moment and pitching moment based on the layout position and layout number of the actuator. According to the equivalent relationship and the correlation relationship, the position of the torque point is adjusted to obtain the optimal torque point, so as to ensure that the actuator truly reproduces the operating state of the high-speed maglev train under the action of aerodynamic load, the actuating force range of each actuator will not have a large difference, and when the numerical simulation calculation result is decoupled to the position of the actuator, its value will not exceed the allowable value of the actuator.

[0064] Please refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of a torque point determination system for a maglev train provided in this application. The torque point determination system for a maglev train includes:

[0065] The first establishment module 1 is used to obtain the correlation between each loading parameter in the numerical simulation calculation and each moment point on the maglev train, the loading parameters including the overturning moment, the yaw moment and the pitching moment;

[0066] The first determining module 2 is used to determine the placement position and number of actuators;

[0069] The third determining module 5 is configured to adjust the position of the target moment point based on the adjustment parameters to obtain the optimal moment point.

[0070] It can be seen that the torque point determination system for a maglev train provided in this embodiment first obtains the correlation between each loading parameter in the numerical simulation calculation and each torque point on the maglev train, and establishes an equivalent relationship between the loading torque of the actuator's action point and the overturning moment, yaw moment and pitching moment based on the layout position and layout number of the actuator. The position of the torque point is adjusted according to the equivalent relationship and the correlation relationship to obtain the optimal torque point, ensuring that the actuator truly reproduces the operating state of the high-speed maglev train under the action of aerodynamic load, and the actuating force range of each actuator will not have a large difference, and when the numerical simulation calculation result is decoupled to the position of the actuator, its value will not exceed the allowable value of the actuator.

[0080] Determine the control parameters of the target moment point based on the equivalent relationship, the control parameters including the force arm of the actuator;

[0081] Based on the association relationship, the control parameters are adjusted until the force of the actuator meets the preset conditions, and the current control parameters are used as the adjustment parameters of the target moment point.

[0082] On the other hand, the present application also provides a device for determining a torque point of a maglev train, comprising:
