Abstract

Description

Technical Field

[0001] The invention relates to the field of impact testing, in particular to a magnetic high-energy landslide impact testing device based on Ampere force acceleration. Background Art

[0002] Impact test equipment is mainly used for structural damage assessment. Commonly used ones include building curtain wall impact tests, which use pendulum acceleration to convert gravitational potential energy into kinetic energy, allowing the test body to collide with the curtain wall. However, its scale is small, and the test body is rigidly connected to the rope, so it is impossible to release the test body and reach a higher final speed. With the existing pendulum acceleration method, the final speed of the test body can reach 15.8m / s, but it cannot meet the speed requirements for irregular block collapse (i.e. >70m / s). The exit speed of the electromagnetic railgun can reach 2500m / s, but the railgun has very high requirements for the test body, requiring a higher hardness, and the railgun will generate high heat during the acceleration process, which will cause abnormal deformation of the test body at high temperature and destroy its original state.

[0003] The invention patent with application number 202311051493.7 discloses a flying rock simulation impact test device for a tunnel entrance protection system, which simulates the impact of falling rocks on the tunnel entrance protection device, adopts an elastic reset force acceleration method, and uses elasticity to accelerate the test body. This method can simulate the impact test of block stones, but the acceleration component and the block are fixed with a clamp, which will destroy the original shape of the test body, and it is impossible to reach a higher final speed, and there is no deceleration process for the loading device. Summary of the invention

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a magnetic high-energy landslide impact testing device based on Ampere force acceleration.

[0005] The technical solution of the present invention to solve the technical problem is to provide a magnetic high-energy collapse and sliding body impact testing device based on Ampere force acceleration, characterized in that the device includes a housing, a left power rail, a carrier platform, a loading box, an acceleration roller, a loading box position sensor, a loading box power supply rail and a right power rail;

[0006] An acceleration roller groove is provided on the bottom surface of the shell; an acceleration roller is rotatably installed on the bottom surface of the carrier platform; the acceleration roller is arranged in the acceleration roller groove, cooperates with the acceleration roller groove, moves along the acceleration roller groove, and realizes the movement of the carrier platform; the carrier box is fixed on the carrier platform, and is used for contactless and non-destructive transportation of the test body; the carrier box power supply rail is fixed on the bottom surface of the shell, and is used for supplying power to the carrier box, so that a magnetic field is generated in the carrier box, and the contactless and non-destructive transportation of the test body in the carrier box is realized; the carrier box position sensor is fixed on the shell, and is in the same vertical plane as the starting end of the insulating rail of the left power-on rail, and is used for detecting whether the carrier box has reached the specified position, and controlling the carrier box to release the test body;

[0007] The left power rail and the right power rail are symmetrically fixed on the bottom surface of the shell; the left power rail and the right power rail have the same structure, including an accelerating rail, an insulating rail, a decelerating rail, a conductive connector, a conductive brush for the power rail, a fixing ring at the beginning of the accelerating rail and a fixing ring at the end of the decelerating rail;

[0008] The accelerating guide rail, the insulating guide rail and the decelerating guide rail are fixedly connected to each other in sequence to form a powered guide rail body; the powered guide rail body is electrically connected to an external power supply; the accelerating guide rail starting end fixing ring and the decelerating guide rail ending fixing ring are respectively fixed to the starting end and the ending end of the powered guide rail body, and are fixedly connected to the outer shell; the conductive connecting piece is nested on the outer side of the powered guide rail body, is slidably connected to the powered guide rail body, is fixedly connected to the carrier platform, and supplies power to the carrier platform; the powered guide rail conductive brush is fixed on the conductive connecting piece; the powered guide rail conductive brush contacts the powered guide rail body.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] (1) The present invention adopts Ampere force electromagnetic track acceleration, and the final speed of the test body is high, which meets the speed requirement when the test body collapses; the magnetic levitation method is used to carry objects, and the carrier and the test body are not in direct contact during the acceleration process, thereby realizing contactless and lossless transportation and rapid release of the test body.

[0011] (2) The energized guide rail of the present invention is divided into an acceleration section, a deceleration section and an insulating section located therebetween. The acceleration section is flexibly connected by a conductive brush, which reduces the wear of the connectors caused by frictional heat generated by high-speed movement; compared with the gravity drop hammer impact test, the acceleration section of the present invention can achieve a higher final release speed. When decelerating, the power is first cut off through the insulating part, and then electromagnetic deceleration is achieved by reverse power supply, which shortens the length of the deceleration section. Preferably, a deceleration spring can be provided for physical deceleration, so as to achieve a mixture of electromagnetic deceleration and physical deceleration and enhance the deceleration effect.

[0012] (3) The present invention uses the magnetic field generated by the coil on the inner wall of the carrier box to place the test object in a suspended state in the carrier box in the form of Lorentz force, and continuously adjusts the magnitude of the Lorentz force acting on the test object in each direction during the acceleration process by monitoring the test object position sensor, thereby ensuring that the test object does not contact the carrier box during the acceleration process, achieving contactless and non-destructive transportation of the test object, maintaining the original shape and characteristics of the test object, and achieving rapid release of the test object. The present invention is particularly suitable for magnetic irregular blocks. Due to the contactless transportation, the shape of the material is not limited by the fixture conditions, thereby achieving accelerated testing of blocks of arbitrary shapes.

[0013] (4) The carrier platform of the present invention is preferably provided with a refrigeration tube to neutralize the heat generated by the magnetic field during the acceleration process, thereby meeting the temperature requirements of different test bodies. Therefore, the present invention is also suitable for rapid impact testing of ice-rock mixed blocks from high collapse points in extreme climate environments.

[0014] (5) The present invention preferably has lifting and rotating functions to achieve a variety of different impact angles, which can better simulate the impact conditions under different working conditions. BRIEF DESCRIPTION OF THE DRAWINGS
