Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aerospace engineering design, specifically relating to a non-contact loading device for applying arbitrary loads to suspended objects, which can meet the multi-condition loading requirements of airborne suspension devices for suspended objects during ground functional deployment tests. Background Technology
[0002] In ground-based functional deployment tests of airborne suspension devices and suspended objects, it is necessary to test whether the separation parameters of the airborne suspension launch system meet given requirements. Ground tests often require applying loads to the suspended object to simulate flight loads such as aerodynamic loads and inertial loads experienced by the suspended object during flight. These loads may be constant loads or variable loads.
[0003] Existing loading devices generally use hydraulic or pneumatic methods. Hydraulic loading can only apply load at the initial separation position; once the suspended object begins to move and its speed increases, loading cannot continue. While pneumatic loading can achieve follow-up loading, it can only achieve constant force loading. Furthermore, due to the contact loading method, the loading device imposes certain constraints on the suspended object, and when the suspended object undergoes pitch or yaw movements, the loading position changes or even fails. Utility Model Content
[0004] This invention proposes a non-contact loading method for applying arbitrary loads to suspended objects. This method utilizes the principle that a wire fixed at a predetermined position on the suspended object will generate electromagnetic force in a magnetic field to apply the load, thus solving the aforementioned problems of existing loading methods.
[0005] This utility model provides a non-contact loading device for applying arbitrary loads to a suspended object. The device consists of an airborne suspension device, a suspended object, a wire, a magnetic pole N, and a magnetic pole S. The suspended object is installed on the lower side of the airborne suspension device. Magnetic poles N and S are installed on both sides of the suspended object at a distance from each other. A wire is arranged on the suspended object along the flight direction.
[0006] Advantageously or alternatively, magnetic poles N and S are mounted on the structures on both sides, with the magnetic poles facing each other.
[0007] Advantageously or alternatively, magnetic poles N and S are single magnetic poles or parallel arrays of magnetic poles.
[0008] Advantageously or alternatively, the magnetic poles N and S are made of permanent magnets or electromagnets.
[0009] Advantageously or alternatively, the wires can be fixed to any position on the suspended object as needed, or multiple wires can be arranged at multiple positions.
[0010] Advantageously or alternatively, the conductors are arranged in pairs before and after the suspension to achieve torque loading.
[0011] Beneficial effects: It can not only achieve non-contact loading, but also the load can be constant or arbitrarily varied. Moreover, the load follows the movement of the suspended object during loading, which solves the above-mentioned problems of existing loading methods.
[0012] The features, functionalities, and advantages already discussed can be implemented independently in various examples, or combined in other examples. Further details of the examples can be seen in the following description and accompanying figures. Attached Figure Description

[0017] The disclosed examples will be described more fully with reference to the accompanying drawings, in which some (but not all) of the disclosed examples are shown. In fact, many different examples may be described, and these examples should not be construed as limited to those set forth herein. Rather, these examples are described so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art.
[0018] See Figure 1-2 The technical solution of this utility model is as follows: The non-contact loading device consists of an airborne suspension device 1, a suspended object 2, a wire 3, a magnetic pole N4, and a magnetic pole S5. The magnetic pole N4 and the magnetic pole S5 are placed opposite each other on the ground. The wire 3 is fixed longitudinally to the suspended object 2. The suspended object 2 is suspended on the airborne suspension device 1, so that the heading of the suspended object 2 is perpendicular to the magnetic lines of force and placed between the two magnetic poles.
[0019] Magnetic poles N4 and S5 can be generated using permanent magnets or electromagnets. They can be a single pole or a parallel array of poles.
[0020] The conductor 3 can be fixed to any position on the suspended object as needed; multiple conductors 3 can also be arranged at multiple positions, and the conductors 3 can be fixed to the suspended object in any way. Torque loading can be achieved by arranging magnetic poles and conductors in pairs before and after the suspended object; constant load loading can be achieved by passing a current of constant magnitude and direction through the conductor 3. Arbitrarily varying load loading can be achieved by changing the magnitude and direction of the current in the conductor 3. Using flexible conductors 3, follow-up loading can be achieved during the movement of the suspended object as it is deployed.
[0021] Before the test, the airborne suspension device 1 is suspended below the weapon mounting platform, and the suspended object 2 is installed below the airborne suspension device 1. At the same time, the magnetic field strength of the magnetic poles is determined according to different working conditions, and the magnitude and direction of the current to be applied to both ends of the conductor 3 are calculated. During the test, the specified current is applied to both ends of the conductor 3 to load the suspended object.
