Description

Technical Field

[0001] The invention belongs to the technical field of scaled model tests of water-entering navigation bodies, and in particular relates to a hypergravity environment simulator using a lifting device. Background Art

[0002] At present, the basic science of high-speed water entry similarity criteria needs to be further improved, and its development also restricts the development of high-speed water entry equipment. The high-speed water entry of a navigation body is a problem involving gas-vapor-liquid-solid multiphase participation and multi-physical field coupling. The nonlinear and non-stationary process with strong transient and strong impact will introduce uncertainty problems. To solve the multidisciplinary cross-cutting problem of the entry of a navigation body into the water, we must first study similarity. Because it is impossible to conduct real physical experiments, we use scaled model experiments.

[0003] However, the existing scaled model test is constrained by the conventional gravity conditions on the earth, which makes the scaled similarity law based on the decompression pool only follow the principle of stress and pressure equality. The simulation ability and accuracy of the scaled model test are subject to the problem of incompatibility of multiple similarity criteria. In order to provide more design freedom for the model test, to avoid unnecessary test conditions and condition simulations for large-scale decompression model engineering tests, and to effectively simulate the cavitation and trajectory of the prototype navigation body entering the water more accurately, the hypergravity environment simulator in the existing technology mainly uses a centrifuge. The hypergravity test system based on the centrifuge can achieve inertial force similarity, and the centrifuge can solve the nonlinear-non-stationary dual non-dynamic process of the navigation body entering the water, and has the ability to study the phase change process and thermodynamic process of the navigation body entering the water. It is necessary to rely on the hypergravity centrifuge test system to reconcile the conflict between the cavitation number and air density similarity of the scaled model test. By achieving structural mechanics similarity under the condition of fluid mechanics similarity in the hypergravity environment, the accuracy of the scaled model test of the navigation body entering the water can be fully supported. However, centrifugal technology has difficulty simulating complex three-dimensional flows, has limitations on the size and shape of the test piece, and introduces additional rotational torque. For example, the centrifuge will generate inevitable Coriolis force during use. The Coriolis force is an inertial force that only changes the direction of the speed of the moving object, not the magnitude of the speed. Therefore, the use of a centrifuge in a scaled model test will affect the test data. Summary of the invention

[0016] A test method of a hypergravity environment simulator using a lifting device specifically comprises the following steps:

[0017] S1: Select a small-scale test device or a large-scale test device according to the test requirements, fill the water tank with water and fix it, and then raise and lower the launch area and the water tank to the required height for the test;

This makes the scaled similarity law of the navigation body based on the decompression pool not only limited to the principle of stress and pressure equality, but also the simulation ability and accuracy of the scaled model test are subject to the problem of incompatibility of multiple similarity criteria, thus getting rid of the existing similarity theory system, providing more design freedom for the model test, and establishing an advanced research and development system in which the ultra-gravity hydrodynamic test system and the engineering full-scale decompression ratio test system complement each other;

During the entry into the water, attached cavitations will be generated on the upper and lower conical surfaces of the navigation body model respectively. The relative position change of the two parts of the model will affect the cavitation morphology and the area of ​​the model wetted area, thereby affecting the fluid resistance.

[0023] 3. The test device of the present invention adopts a small-scale test device or a large-scale test device. The two sets of test devices are designed with different scale model stiffness characteristics, which solves the limitations of centrifugal technology on the size and shape of the test piece, and accurately measures the model mass and stiffness before the test, assisting in studying the coupling mechanism between the deformation and fragmentation of the water-entering structure and the attached cavitation, and providing accurate model test support for the dynamic response of the high-speed water-entering strong impact structure and the design of load reduction schemes.

9. The hypergravity environment simulator using a lifting device according to claim 3, characterized in that: An internal measurement system is arranged in the navigation body barrel section (9), and the internal measurement system comprises a data acquisition device, a pressure sensor, an acceleration sensor, a data acquisition and recording unit and an embedded rechargeable battery pack.

10. A test method of a hypergravity environment simulator using a lifting device as claimed in claim 1, characterized in that: The specific steps include: S1: Select a small-scale test device or a large-scale test device according to the test requirements, fill the water tank with water and fix it, and then lift the launch device and the water tank to the required height for the test; S2: If a small-scale test device is selected, the small-scale driving device provided in the slide lift (1) drives the water tank support platform (6) to move upward with uniform acceleration; if a large-scale test device is selected, the large-scale driving device provided in the towing device (16) drives the towing device (16) to rotate, and drives the lifting bracket (14) to move through gear meshing, thereby causing the large-scale water tank (18) to move upward with uniform acceleration; S3: The electromagnetic valve (12) is activated to discharge the gas in the high-pressure gas cylinder (11) into the launch tube (3) to steadily push the vehicle out of the tube. After the vehicle is out of the tube, it continues to move, and the water tank continues to move upward with uniform acceleration until the vehicle enters the water, the water tank stops rising, and the internal measurement system in the tube section (9) of the vehicle completes data monitoring.
