[0069] With the improvement of permanent magnet performance and the development of production and processing technology, permanent magnet electric suspension becomes the object of more and more people's research. Compared with low-temperature superconducting electric suspension, permanent magnet electric suspension has the advantages of low construction cost, stable and reliable system, etc. The existing permanent magnet arrangement modes mainly include ordinary array arrangement mode and Halbach array arrangement mode.

[0070] Referring to Figure 1 , Figure 1 is a structural schematic diagram of an ordinary permanent magnet array. The adjacent permanent magnets of the ordinary permanent magnet array are attached and the north-south pole directions are opposite. Each permanent magnet is vertically arranged at the bottom of a moving object. Since the adjacent permanent magnets of the ordinary permanent magnet array are attached, the magnetic field transmitted from the north pole of one permanent magnet will have more components transmitted from the south pole of the other permanent magnet, resulting in low utilization of the ordinary permanent magnet array.

[0071] Referring to Figure 2 and Figure 3 , Figure 2 is a structural schematic diagram of an ideal Halbach permanent magnet array, Figure 3 is a structural schematic diagram of a commonly used Halbach permanent magnet array. The Halbach array has been widely used due to its excellent suspension performance, but the processing and installation of the Halbach array magnet are relatively complex.

[0072] Therefore, in the permanent magnet arrangement method provided in the present application, the suspension performance of the permanent magnet electric suspension is improved, the utilization of the permanent magnet is improved, the permanent magnet arrangement is simplified, and the construction cost of the permanent magnet electric suspension device is reduced.

[0073] In order to enable personnel in the technical field to better understand the present application scheme, the present application will be further described in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0074] Referring to Figure 4 , Figure 4 is an implementation flowchart of the first permanent magnet arrangement method in the embodiments of the present application. The method can include the following steps:

[0075] S401: Obtain a first permanent magnet arrangement array in which the adjacent permanent magnets are attached and the north-south pole directions are opposite.

[0076] In the first permanent magnet arrangement array, each permanent magnet is vertically arranged at the bottom of a moving object.

[0077] The first permanent magnet arrangement array is obtained, wherein adjacent permanent magnets are attached and arranged in opposite directions of the south and north poles, and each permanent magnet in the first permanent magnet arrangement array is vertically arranged at the bottom of the moving object.

[0078] As shown in Figure 1 the initial first permanent magnet arrangement array, adjacent permanent magnets are attached and arranged in opposite directions of the south and north poles, and each permanent magnet in the first permanent magnet arrangement array is vertically arranged at the bottom of the moving object, that is, each permanent magnet in the first permanent magnet arrangement array is vertically arranged.

[0079] S402: Obtain the first suspension force of the first permanent magnet arrangement array.

[0080] The first permanent magnet arrangement array provides an upward suspension force for the moving object. After obtaining the first permanent magnet arrangement array in which adjacent permanent magnets are attached and arranged in opposite directions of the south and north poles, the first suspension force of the first permanent magnet arrangement array is obtained.

[0081] S403: Add a preset interval between adjacent two permanent magnets in the first permanent magnet arrangement array to obtain a second permanent magnet arrangement array.

[0082] After obtaining the first suspension force of the first permanent magnet arrangement array, a preset interval is added between adjacent two permanent magnets in the first permanent magnet arrangement array to obtain a second permanent magnet arrangement array.

[0083] It should be noted that the preset interval can be set and adjusted according to actual conditions, and the present application embodiment does not limit this.

[0084] S404: Obtain the second suspension force of the second permanent magnet arrangement array.

[0085] The intervals between adjacent permanent magnets in the permanent magnet arrangement array are different, and the suspension forces generated are also different. After adding a preset interval between adjacent two permanent magnets in the first permanent magnet arrangement array to obtain a second permanent magnet arrangement array, the second suspension force of the second permanent magnet arrangement array is obtained.

[0086] S405: When it is determined that the second suspension force is greater than the first suspension force, the current second permanent magnet arrangement array is determined as a new first permanent magnet arrangement array, the current second suspension force is determined as a new first suspension force, and the step S403 is returned to be executed.

[0087] After obtaining the second levitation force of the second permanent magnet arrangement array after adding the preset interval between the two adjacent permanent magnets in the first permanent magnet arrangement array, the first levitation force corresponding to the first permanent magnet arrangement array and the second levitation force of the second permanent magnet arrangement array are compared in size. When it is determined that the second levitation force is greater than the first levitation force, it is indicated that the levitation force is in an increasing trend after the preset interval is added between the permanent magnets. The current second permanent magnet arrangement array is determined as a new first permanent magnet arrangement array, and the current second levitation force is determined as a new first levitation force. The preset interval is added again between the two adjacent permanent magnets in the new first permanent magnet arrangement array, and the comparison between the levitation force after the interval is added and the levitation force before the interval is added is performed again, so as to determine whether to continue to add the preset interval between the adjacent permanent magnets.

[0088] S406: When it is determined that the second levitation force is less than or equal to the first levitation force, the interval value between the current adjacent permanent magnets is determined as a target interval value, and the current first permanent magnet arrangement array is determined as a target permanent magnet arrangement array.

[0089] After obtaining the second levitation force of the second permanent magnet arrangement array after adding the preset interval between the two adjacent permanent magnets in the first permanent magnet arrangement array, the first levitation force corresponding to the first permanent magnet arrangement array and the second levitation force of the second permanent magnet arrangement array are compared in size. When it is determined that the second levitation force is less than or equal to the first levitation force, it is indicated that the levitation force is in a decreasing trend after the preset interval is added between the permanent magnets. Then, the interval value between the current adjacent permanent magnets is determined as a target interval value, and the current first permanent magnet arrangement array is determined as a target permanent magnet arrangement array. The embodiment of the present application effectively improves the levitation force of the levitation device, improves the utilization rate of the permanent magnet, and improves the levitation performance of the permanent magnet electric suspension when the number of permanent magnets in the permanent magnet array is the same.

[0090] According to the above technical solution, the preset interval is gradually added between the two adjacent permanent magnets in the first permanent magnet arrangement array in which the first permanent magnets are attached and arranged in opposite north-south polar directions. After each addition is completed, the second levitation force of the second permanent magnet arrangement array after the interval addition is completed and the first levitation force of the first permanent magnet arrangement array before the interval addition are compared in size, and then the target interval value with the largest levitation force under the condition of the same permanent magnet usage is found. The permanent magnet arrangement array with the target interval value between the adjacent permanent magnets is determined as a target permanent magnet arrangement array. Thus, the levitation force of the levitation device is effectively improved, the levitation performance of the permanent magnet electric suspension is improved, the float-to-weight ratio is increased, and the utilization rate of the permanent magnet is improved under the condition of the same permanent magnet usage. The permanent magnet arrangement is simplified, and the construction cost of the permanent magnet electric suspension device is reduced.

[0091] It should be noted that based on the above embodiment, the application embodiment also provides a corresponding improvement scheme. In the subsequent embodiments, reference can be made between the same steps or corresponding steps in the above embodiments, and the corresponding benefits can also be mutually referred to. In the following improved embodiments, it will not be described one by one.

[0092] Reference is made to Figure 5 , Figure 5 is the implementation flowchart of the second permanent magnet arrangement method in the application embodiment. The method can include the following steps:

[0093] S501: Obtain a first permanent magnet arrangement array in which adjacent permanent magnets are attached and arranged with opposite north-south poles.

[0094] Among them, each permanent magnet in the first permanent magnet arrangement array is vertically arranged at the bottom of the moving object.

[0095] S502: Obtain the first levitation force of the first permanent magnet arrangement array.

[0096] S503: Obtain the first magnetic resistance of the first permanent magnet arrangement array.

[0097] The first permanent magnet arrangement array will generate a magnetic resistance opposite to the moving direction of the moving object. After obtaining the first permanent magnet arrangement array in which adjacent permanent magnets are attached and arranged with opposite north-south poles, the first magnetic resistance of the first permanent magnet arrangement array is obtained.

[0098] S504: Calculate the first float-to-resistance ratio according to the first levitation force and the first magnetic resistance.

[0099] After obtaining the first levitation force and the first magnetic resistance of the first permanent magnet arrangement array, the first float-to-resistance ratio is calculated according to the first levitation force and the first magnetic resistance, that is, the first float-to-resistance ratio is obtained by calculating the ratio of the first levitation force and the first magnetic resistance.

[0100] S505: Add a preset interval between adjacent two permanent magnets in the first permanent magnet arrangement array to obtain a second permanent magnet arrangement array.

[0101] S506: Obtain the second levitation force of the second permanent magnet arrangement array.

[0102] S507: Obtain the second magnetic resistance of the second permanent magnet arrangement array.

[0103] The interval between adjacent permanent magnets in the permanent magnet arrangement array is different, and the generated magnetic resistance is also different. After adding a preset interval between adjacent two permanent magnets in the first permanent magnet arrangement array to obtain a second permanent magnet arrangement array, the second magnetic resistance of the second permanent magnet arrangement array is obtained.

[0104] S508: Calculate the second float-to-drag ratio according to the second levitation force and the second magnetic drag force.

[0105] After obtaining the second levitation force and the second magnetic drag force of the second permanent magnet arrangement array, the second float-to-drag ratio is calculated according to the second levitation force and the second magnetic drag force, that is, by calculating the ratio of the second levitation force and the second magnetic drag force, the second float-to-drag ratio is obtained.

[0106] S509: When it is determined that the second float-to-drag ratio is greater than the first float-to-drag ratio, it is judged whether the distance between the current adjacent permanent magnets is greater than a preset value. If yes, step S510 is executed, and if no, step S511 is executed.

[0107] After obtaining the second float-to-drag ratio of the second permanent magnet arrangement array after adding a preset interval between the two adjacent permanent magnets in the first permanent magnet arrangement array, the first float-to-drag ratio corresponding to the first permanent magnet arrangement array and the second float-to-drag ratio of the second permanent magnet arrangement array are compared. When it is determined that the second float-to-drag ratio is greater than the first float-to-drag ratio, it is judged whether the distance between the current adjacent permanent magnets is greater than a preset value. If yes, it means that the distance between the current adjacent permanent magnets has exceeded the preset distance range, and step S510 is executed. If no, it means that the distance between the current adjacent permanent magnets has not exceeded the preset distance range, and step S511 is executed.

[0108] It should be noted that the preset value can be set and adjusted according to actual conditions, and the embodiments of the present application do not limit this. For example, it can be set to a value slightly larger than the width of a single permanent magnet sensing plate.

[0109] In a specific embodiment of the present application, judging whether the distance between the current adjacent permanent magnets is greater than a preset value can include the following steps:

[0110] Judging whether the distance between the current adjacent permanent magnets is greater than an upper limit of the interval set according to the width of a single permanent magnet sensing plate.

[0111] The upper limit of the interval between adjacent permanent magnets is set according to the width of a single permanent magnet sensing plate in advance. When it is determined that the second float-to-drag ratio is greater than the first float-to-drag ratio, it is necessary to first judge whether the distance between the current adjacent permanent magnets is greater than the upper limit of the interval set according to the width of a single permanent magnet sensing plate. By setting the upper limit of the interval between adjacent permanent magnets according to the width of a single permanent magnet sensing plate, the utilization rate of the permanent magnet is maximized while avoiding the distance between adjacent permanent magnets in the permanent magnet arrangement array being too large.

[0112] S510: The current first permanent magnet arrangement array is determined as the target permanent magnet arrangement array.

[0113] When it is determined that the second floatage-resistance ratio is greater than the first floatage-resistance ratio and the distance between the current adjacent permanent magnets is greater than the preset value, it is indicated that the distance between the current adjacent permanent magnets has exceeded the preset distance range, and the interval between the adjacent permanent magnets cannot be continuously increased. The current first permanent magnet arrangement array is determined as the target permanent magnet arrangement array.

[0114] S511: The current second permanent magnet arrangement array is determined as a new first permanent magnet arrangement array, the current second suspension force is determined as a new first suspension force, the current second magnetic resistance force is determined as a new first magnetic resistance force, the current second floatage-resistance ratio is determined as a new first floatage-resistance ratio, and the step S505 is returned to be executed.

[0115] When it is determined that the second floatage-resistance ratio is greater than the first floatage-resistance ratio and the distance between the current adjacent permanent magnets is not greater than the preset value, it is indicated that the suspension force is in an increasing trend after the preset interval is added between the permanent magnets, and the distance between the current adjacent permanent magnets has not exceeded the preset distance range. The current second permanent magnet arrangement array is determined as a new first permanent magnet arrangement array, the current second suspension force is determined as a new first suspension force, the current second magnetic resistance force is determined as a new first magnetic resistance force, the current second floatage-resistance ratio is determined as a new first floatage-resistance ratio, and the preset interval between the adjacent two permanent magnets in the new first permanent magnet arrangement array is added again. The suspension force after the interval is increased and the floatage-resistance ratio before the interval is increased are compared in the next round of interval increase, so as to determine whether the preset interval is continuously added between the adjacent permanent magnets.

[0116] S512: When it is determined that the second floatage-resistance ratio is less than or equal to the first floatage-resistance ratio, the interval value between the current adjacent permanent magnets is determined as a target interval value, and the current first permanent magnet arrangement array is determined as a target permanent magnet arrangement array.

[0117] After the second floatage-resistance ratio of the second permanent magnet arrangement array after the preset interval is added between the adjacent two permanent magnets in the first permanent magnet arrangement array is obtained, the first floatage-resistance ratio corresponding to the first permanent magnet arrangement array and the second floatage-resistance ratio of the second permanent magnet arrangement array are compared in size. When it is determined that the second floatage-resistance ratio is less than or equal to the first floatage-resistance ratio, it is indicated that the floatage-resistance ratio is in a decreasing trend after the preset interval is added between the permanent magnets. Therefore, the interval value between the current adjacent permanent magnets is determined as a target interval value, and the current first permanent magnet arrangement array is determined as a target permanent magnet arrangement array. By taking the floatage-resistance ratio as an index for determining the interval value between the adjacent permanent magnets, the determination accuracy of the interval value between the adjacent permanent magnets is greatly improved.

[0121] S602: Obtain a first levitation force of the first permanent magnet arrangement array.

[0122] S603: Obtain a magnet gravity of each permanent magnet.

[0123] The permanent magnet has its own gravity. After obtaining the first permanent magnet arrangement array in which adjacent permanent magnets are attached and arranged with opposite north-south poles, the magnet gravity of each permanent magnet is obtained.

[0124] S604: Calculate a first float-to-weight ratio according to the first levitation force and the magnet gravity.

[0125] After obtaining the first levitation force and the magnet gravity of the first permanent magnet arrangement array, the first float-to-weight ratio is calculated according to the first levitation force and the magnet gravity.

[0126] S605: Add a preset interval between adjacent two permanent magnets in the first permanent magnet arrangement array to obtain a second permanent magnet arrangement array.

[0129] After obtaining the second levitation force of the second permanent magnet arrangement array, the second float-to-weight ratio is calculated according to the second levitation force and the magnet gravity, that is, the second float-to-weight ratio is obtained by calculating the ratio of the second levitation force and the second float-to-weight ratio.

[0130] S608: When it is determined that the second float-to-weight ratio is greater than the first float-to-weight ratio, the current second permanent magnet arrangement array is determined as a new first permanent magnet arrangement array, the current second levitation force is determined as a new first levitation force, and the current second float-to-weight ratio is determined as a new first float-to-weight ratio, and the step S605 is returned to execute.

[0131] After the second levitation-to-weight ratio of the second permanent magnet arrangement array after adding the preset interval between the adjacent two permanent magnets in the first permanent magnet arrangement array is obtained, the first levitation-to-weight ratio corresponding to the first permanent magnet arrangement array and the second levitation-to-weight ratio of the second permanent magnet arrangement array are compared in size. When it is determined that the second levitation-to-weight ratio is greater than the first levitation-to-weight ratio, it is indicated that the levitation-to-weight ratio is in an increasing trend after the preset interval is added between the permanent magnets, the current second permanent magnet arrangement array is determined as a new first permanent magnet arrangement array, the current second levitation force is determined as a new first levitation force, and the current second levitation-to-weight ratio is determined as a new first levitation-to-weight ratio. The preset interval is added again between the adjacent two permanent magnets in the new first permanent magnet arrangement array, and the comparison between the levitation-to-weight ratio after the interval is added and the levitation-to-weight ratio before the interval is added is performed in the next round, so as to determine again whether the preset interval is added between the adjacent permanent magnets.

[0132] S609: When it is determined that the second levitation-to-weight ratio is less than or equal to the first levitation-to-weight ratio, the interval value between the adjacent permanent magnets is determined as a target interval value, and the current first permanent magnet arrangement array is determined as a target permanent magnet arrangement array.

[0133] After the second levitation force of the second permanent magnet arrangement array after adding the preset interval between the adjacent two permanent magnets in the first permanent magnet arrangement array is obtained, the first levitation force corresponding to the first permanent magnet arrangement array and the second levitation force of the second permanent magnet arrangement array are compared in size. When it is determined that the second levitation force is less than or equal to the first levitation force, it is indicated that the levitation force is in a decreasing trend after the preset interval is added between the permanent magnets. Then, the interval value between the adjacent permanent magnets is determined as a target interval value, and the current first permanent magnet arrangement array is determined as a target permanent magnet arrangement array. By taking the levitation-to-weight ratio as an index for determining the interval value between the adjacent permanent magnets, the determination accuracy of the interval value between the adjacent permanent magnets is greatly improved, the levitation-to-weight ratio is increased, the utilization rate of the permanent magnet is improved, and the suspension performance of the permanent magnet electric suspension is improved.
