Description

Technical Field

[0001] The present invention relates to the field of vibration simulation technology, and in particular to a combined vibration environment simulation device. Background Art

[0002] Initially, earthquake resistance research was primarily conducted through post-earthquake observations. Researchers placed observation instruments on structures in the earthquake zone and then observed and recorded the structures' response to the strong earthquake. However, actual strong earthquakes are relatively rare, and obtaining research data based on actual earthquakes is both extremely rare and time-consuming.

[0003] Later, earthquake simulation vibration tables were built, but most of them were small in scale and had single experimental functions, and could not simulate the real conditions under the influence of earthquakes, waves, and water flows at the same time.

[0004] After countless deductions and demonstrations, a vibration environment simulation device combining an underwater vibration table array and a vibration table was built.

[0005] Underwater vibration arrays not only provide a controllable and stable underwater vibration environment for marine engineering, but also simulate the impact of marine environmental testing on offshore structures. To ensure accurate simulation of the marine environment, flow generation devices must be designed into the underwater vibration arrays. Due to the large size of underwater vibration arrays and the large flow rates they require, existing facilities often store the water used for wave and flow generation in external reservoirs. Constantly filling reservoirs with water can easily lead to water deterioration, and due to the large volume of water in reservoirs, water replacement is difficult, necessitating regular water purification.

[0006] A common problem encountered with existing external reservoirs for water purification is that, after being transported back to the reservoir, the purified water mixes with the unpurified water already in the original reservoir. Due to the irregular flow of water within the reservoir, it is difficult for operators to determine whether the water in the reservoir has been purified to standard. For example, if the water being drawn for purification happens to be already purified water, the unpurified water may not be drawn up due to the current, leading to misjudgment by the purification operator.

[0007] Vibration tables are widely used in engineering, architecture, aerospace, and earthquake research. They typically consist of a highly rigid and stable platform and a vibration table tank. The structure or device under test is placed in the tank, and a motor, hydraulic system, or electromagnetic drive system generates vibrations of a specific frequency, subjecting the structure or device to mechanical vibrations of varying frequencies and amplitudes. Their advantages include simulating real-world conditions, high load capacity, a wide frequency range, accuracy, repeatability, and accelerated test cycles. They are currently the most intuitive and effective large-scale equipment for studying seismic effects.

[0008] Vibration tables typically operate at high frequencies and for long periods of time, and their internal exciters are prone to overheating and shutting down. To ensure the vibration table remains operational, the exciter must be cooled. Large vibration tables have high power ratings and generate significant heat, necessitating the construction of cooling pools. However, existing cooling pools are limited in functionality, consume significant water, have low heat dissipation efficiency, and occupy a large area, leaving them idle when the vibration table is not in use.

[0009] How to develop a combined vibration environment simulation device that can combine the facility vibration simulation system and the underwater vibration simulation system, so as to purify the water in the reservoir, cool the vibration table, and simulate the destructive mechanism and characteristics of earthquakes, waves and water flows on building facilities, has become a technical problem that needs to be solved urgently by technical personnel in this field.

[0052] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0053] like Figure 1-10 As shown, a combined vibration environment simulation device includes a facility vibration simulation system and an underwater vibration simulation system, wherein the facility vibration simulation system is connected to the underwater vibration simulation system through a pipeline, and a cooling unit is provided on the pipeline;

[0054] The underwater vibration simulation system includes an underground water pool 1 and an annular reservoir. The underground water pool 1 is located at the center above the annular reservoir and is connected to the annular reservoir through a flow corridor. An underwater vibration array 29 is installed inside the underground water pool 1.

[0055] The facility vibration simulation system includes an assembled reaction wall and a vibration table 6. The assembled reaction wall is installed on the ground. The vibration table 6 is installed on the upper surface of the assembled reaction wall. The vibration table 6 is connected to the flow corridor through the pipeline penetrating the reservoir water inlet 13.

[0056] Specifically, the annular reservoir includes an outer reservoir 7 and an inner reservoir 16. The inner reservoir 16 is located in the center of the outer reservoir 7. The underground water pool 1 is located above the inner reservoir 16. The outer reservoir 7 is connected to the inner reservoir 16 through an inner and outer reservoir channel.

[0057] A partition wall is provided at the end of the outer water reservoir 7, and a purified water outlet 9 and a purified water inlet 10 are provided on the outer water reservoir 7 on both sides of the partition wall.

[0058] A guide wall 17 is installed in the inner water reservoir 16. The water in the inner water reservoir 16 not only flows in an orderly manner under the constraint of the guide wall 17, playing a water diversion role, ensuring the orderly flow of water during water purification, but also reduces the overall span of the underground water tank floor to provide support for the upper equipment, thereby avoiding the impact of a large span on the structural safety of the upper equipment and the underground water tank.

[0059] A partition wall 15 is provided at the connection point between the outer reservoir 7 and the inner reservoir 16 , one end of the partition wall 15 is connected to the inner wall of the outer reservoir 7 , and the other end of the partition wall 15 is connected to the guide wall 17 ;

[0060] In specific implementation, the capacity of the inner and outer reservoirs is determined by the function of the equipment. The capacity of the inner reservoir 16 is certain, and the capacity of the outer reservoir 7 can be further determined according to the required function of the equipment; further, the annular shapes of the inner and outer reservoirs include square rings, circular rings and elliptical rings.

[0061] Specifically, the purified water outlet 9 and the purified water inlet 10 are connected to an external water purification device to circulate and purify the reservoir water to prevent water deterioration.

[0062] Specifically, the flow-making gallery includes an upper flow-making gallery 3 and a lower flow-making gallery 8. The lower flow-making gallery 8 is located in a loop formed between the outer reservoir 7 and the inner reservoir 16. The lower flow-making gallery 8 and the outer reservoir 7 are connected by a gallery pumping pipe 11 and a gallery return pipe 12 to realize water exchange. The water stored in the outer reservoir 7 is pumped into the lower flow-making gallery 8 through the gallery pumping pipe 11, and the water in the lower flow-making gallery 8 flows back to the outer reservoir 7 through the gallery return pipe 12.

[0063] The upper flow-generating gallery 3 is located one floor above the lower flow-generating gallery 8 , and the two are connected by floor holes; the upper flow-generating gallery 3 is connected to the underground water pool 1 through a flow-generating pump 2 .

[0064] Specifically, two upper flow-generating corridors 3 are symmetrically provided and located on both sides of the underground water pool 1 , and a plurality of flow-generating pumps 2 are provided and evenly distributed in the upper flow-generating corridors 3 .

[0065] Specifically, a ramp 14 is provided in the lower flow-making corridor 8, and the inner and outer reservoir channels pass through the ramp 14;

[0066] During purification, first close the corridor pumping pipe 11 and the corridor return pipe 12 for pretreatment; then open the purified water outlet 9 and the purified water inlet 10, and the water in the inner reservoir 16 flows unidirectionally and orderly from the inner and outer reservoir channels to the outer reservoir 7 under the constraint of the guide wall 17. The water in the outer reservoir 7 is pumped from the purified water outlet 9 into the external water purification equipment for purification. The purified water flows back to the outer reservoir 7 from the purified water inlet 10, and the water flowing back from the outer reservoir 7 flows back to the inner reservoir 16 from the inner and outer reservoir channels on the other side.

[0067] Specifically, the cooling unit includes an oil-water heat exchanger 30 and a water-water heat exchanger 31, and the oil-water heat exchanger 30 and the water-water heat exchanger 31 both include a liquid tank and a radiating pipe located in the liquid tank, and the liquid tank and the radiating pipe are both provided with a liquid inlet and a liquid outlet. The liquid inlet and liquid outlet of the radiating pipe of the oil-water heat exchanger 30 are connected to the hydraulic system of the vibration table 6, and the liquid inlet and liquid outlet of the radiating pipe of the water-water heat exchanger 31 are respectively connected to the liquid outlet and liquid inlet of the liquid tank of the oil-water heat exchanger, and the liquid inlet and liquid outlet of the liquid tank of the water-water heat exchanger 31 are respectively communicated with the lower flow gallery 8, and the oil-water heat exchanger 30 and the water-water heat exchanger 31 are both provided with multiple groups;

[0068] The oil-water heat exchanger 30 and water-water heat exchanger 31 are equipped with circulation pumps to keep the liquid flowing. Since the hydraulic oil in the heat pipe of the oil-water heat exchanger 30 has a high pressure, it is cooled with pure water to protect the pipe. The water in the heat pipe of the water-water heat exchanger 31 has a low pressure, so it can be cooled with water from the lower flow corridor.

[0069] When in use, the hydraulic oil in the vibrating table 6 circulates into the radiating pipes in the oil-water heat exchanger 30, and the pure water in the liquid tank of the oil-water heat exchanger 30 cools the radiating pipes in the oil-water heat exchanger 30; the pure water in the liquid tank of the oil-water heat exchanger 30 circulates into the radiating pipes in the water-water heat exchanger 31; the water-water heat exchanger 31 draws reservoir water from the lower flow-making corridor on the right side into the liquid tank of the water-water heat exchanger 31 to cool the radiating pipes in the water-water heat exchanger 31; the reservoir water in the liquid tank of the water-water heat exchanger 31 is discharged into the left side of the lower flow-making corridor after heat exchange, and the water in the left side of the lower flow-making corridor is discharged into the left side of the lower flow-making corridor. When the reservoir water reaches a certain amount, the gallery return pipe 12 connected to it is opened to discharge into the left side of the outer reservoir 7. The pressure on the left side of the outer reservoir 7 increases, and it flows to the inner reservoir 16 through the inner and outer reservoir channels connected to it to relieve pressure. The inner reservoir 16 flows to the right side of the outer reservoir through another inner and outer reservoir channel to relieve pressure until the water levels of the inner and outer reservoirs are level, realizing flow heat dissipation, which improves the heat dissipation efficiency compared to a static water pool; when the reservoir water on the right side of the current flow-making gallery drops to a certain amount, the gallery pumping pipe 11 connected to it is opened to pump water from the right side of the outer reservoir 7 for replenishment.

[0070] When the vibration table 6 is not in use, the cooling system can be used as a flow-making facility without causing idle resources. Furthermore, when there are flow-making facilities near the vibration table, the flow-making facilities can also be modified on a small scale and used as a cooling system to save the cost of building a cooling water pool.

[0071] Specifically, the assembled reaction wall includes a reaction wall 18 and a lifting steel beam 21. The reaction wall 18 is square and made of concrete. One end of the lifting steel beam 21 is relatively pre-buried in the side wall of the reaction wall 18, and the other end of the lifting steel beam 21 passes through the outer wall of the side wall. The arrangement of the lifting steel beam facilitates the lifting and assembly of the reaction wall. The end of the lifting steel beam has a hole and is provided with a stiffening rib. Four lifting steel beams are provided on the reaction wall, of which the upper two lifting steel beams can be used for crane lifting connection to realize long-distance and large-scale lifting and movement of the reaction wall, and the lower two lifting steel beams can realize slight movement between the two reaction walls, that is, the upper lifting steel beam of the lower reaction wall is used as the bottom, and the lower lifting steel beam of the upper reaction wall is used as the top, and a jack is provided to realize micro-movement installation between the two reaction walls.

[0072] Loading holes 19 are pre-buried on the other two opposite side walls of the reaction wall 18. Both ends of the loading holes 19 are flush with the side walls. The loading holes are used to connect the actuator supports.

[0073] Prestressed reinforcement holes 20 are passed through the upper and lower ends of the reaction wall 18. Stirrups 28 are arranged on the outer circumference of the prestressed reinforcement holes 20. The prestressed reinforcement holes are made of steel pipes, and square steel plates are welded to both ends of the steel pipes. A number of stirrups 28 are arranged in the axial direction of the steel pipes to increase the bonding area with the concrete and improve the pull-out resistance.

[0074] The upper and lower ends of the reaction wall 18 are provided with shear holes 22;

[0075] Anchor bars 23 are pre-buried in the ground foundation, and the plurality of reaction walls 18 are connected by prestressed bars passing through the prestressed bar holes 20;

[0076] The lower end of the prestressed tendon is connected to the anchoring tendon 23 via a connector 24;

[0077] A shear member 25 is placed in the shear hole 22 between the upper and lower opposite surfaces of the two reaction walls 18 to increase the vertical rigidity of the concrete reaction wall and prevent sliding.

[0078] A prestressed tendon nut 27 is installed at the upper end of the prestressed tendon, and the lower surface of the prestressed tendon nut 27 abuts against the upper surface of the pad 26, and the lower surface of the pad 26 abuts against the upper surface of the reaction wall 18; the reaction walls are connected by prestressed tendons, and by arranging different numbers of reaction walls, the height of the reaction wall can be changed to meet the requirements of different mixed simulation tests. The top of the prestressed tendon is fastened to the prestressed tendon nut 27 through the pad 26 to ensure the stability of the reaction wall connection and provide solid support for the vibration table.
