Description

Technical Field

[0001] The present invention relates to the technical field of simulation test devices, and in particular, to an ice load impact simulation experiment device for a submerged body floating upright and breaking ice. Background Art

[0002] At present, the traditional methods of submerged body ice-breaking experiments have significant limitations. Specifically, past experiments often only targeted the local structure of the sail, completely ignoring the constraint effect of the hull part on the sail, which led to a huge difference between the experimental results and the actual situation. With the continuous development of polar ocean submersible devices, more stringent and complex requirements have been put forward for the ice-breaking ability of submerged bodies. However, the existing ice load impact experiment devices have obvious deficiencies in design: they fail to fully consider the conditions for simulating the hull constraint, and at the same time, they cannot comprehensively cover key factors such as different carrying capacities, displacements, and ice layer thicknesses. Therefore, it is difficult to accurately simulate the true response of the sail structure when the submersible breaks ice while floating. Summary of the Invention

[0003] Embodiments of the present invention provide an ice load impact simulation experiment device for a submerged body floating upright and breaking ice to solve the technical problem that the simulation test device in the prior art cannot more closely simulate the true state when the submersible breaks ice while floating.

[0013] In the present invention, the ice placement groove is installed at the bottom of the impact base frame and is used to accommodate sea ice of different thicknesses, and can flexibly adjust the ice layer thickness according to experimental requirements to simulate the actual working conditions under different icebreaking environments. This structural design enables the device to simulate the icebreaking process of the submerged body's fairing structure under different load weights, different displacements, and different ice layer thickness conditions by adjusting the parameters of the magnetically controlled counterweight impact actuator (drive motor) and the thickness of the sea ice in the ice placement groove without changing its own structure; it can not only accurately simulate the icebreaking process of the fairing under the restraint conditions of the hull, but also flexibly adjust the acceleration of the upward icebreaking to ensure that the fairing structure remains in a positive floating state before and after impact, and most closely approximates the real state of the submersible when it breaks ice and floats upward.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0026] Such as Figures 1 to 4As shown in the figure, an embodiment of the present invention provides an ice load impact simulation experimental device for a submerged body to break ice in a positive floating state, including an impact base frame 10, a magnetically controlled counterweight impact actuator 20 installed on the top of the impact base frame 10, a submerged body fairing simulation body 30 magnetically connected to the magnetically controlled counterweight impact actuator 20, and an ice placement groove 40 installed at the bottom of the impact base frame 10 for accommodating sea ice of different thicknesses; the submerged body fairing simulation body 30, under the control of the magnetically controlled counterweight impact actuator 20, freely falls at a preset positive floating ice-breaking angle to impact the sea ice in the ice placement groove 40. Among them, the core components such as the impact base frame 10, the magnetically controlled counterweight impact actuator 20, the submerged body fairing simulation body 30, and the ice placement groove 40 form a highly integrated simulation experimental system. The impact base frame 10 is the main frame of the entire device, providing a stable installation foundation and support platform for other components. The magnetically controlled counterweight impact actuator 20 is installed on the top of the impact base frame 10, and the motion state of the submerged body fairing simulation body 30 is controlled by magnetic force, and the acceleration of its upward floating and ice-breaking can be accurately adjusted. The submerged body fairing simulation body 30 is connected to the magnetically controlled counterweight impact actuator 20 through magnetic connection, and can, under the control of the actuator, freely fall at a preset positive floating ice-breaking angle to impact the sea ice in the ice placement groove 40, so as to simulate the stress condition of the fairing structure of the submerged body during the actual ice-breaking process.

[0027] In the present invention, the ice placement groove 40 is installed at the bottom of the impact base frame 10 for accommodating sea ice of different thicknesses, and the ice layer thickness can be flexibly adjusted according to experimental requirements to simulate the actual working conditions under different ice-breaking environments. This structural design enables the device to simulate the ice-breaking process of the submerged body fairing structure under different load weights, different displacements, and different ice layer thickness conditions by adjusting the parameters of the magnetically controlled counterweight impact actuator 20 (drive motor 21) and the thickness of the sea ice in the ice placement groove 40 without changing its own structure; not only can it accurately simulate the ice-breaking process of the fairing under the restraint conditions of the hull, but also the acceleration of upward floating and ice-breaking can be flexibly adjusted to ensure that the submerged body fairing simulation body 30 (fairing structure) remains in a positive floating state before and after impact, and the real state of the submersible when floating and breaking ice is simulated as close to the actual situation as possible.

[0028] In one embodiment, as Figures 1 to 2As shown, the magnetically controlled counterweight impact actuator 20 includes a drive motor 21, a magnetic chuck 22 connected to the drive motor 21, and a counterweight slider 23 magnetically coupled to the magnetic chuck 22; the counterweight slider 23 is slidably connected to the impact base frame 10; the submerged body hull simulation body 30 is installed on the end face of the counterweight slider 23 facing the ice placement tank 40. Understandably, the drive motor 21 serves as a power source and can precisely control the magnitude and variation of the magnetic force of the magnetic chuck 22. The magnetic chuck 22 is connected to the counterweight slider 23 by magnetic force. This magnetic connection method not only provides a stable connection force but also can quickly release the counterweight slider 23 when needed to achieve free-fall motion. The sliding connection design of the counterweight slider 23 and the impact base frame 10 ensures its smooth movement in the vertical direction and can flexibly adjust the position and attitude according to experimental requirements.

[0029] Understandably, the submerged body hull simulation body 30 is installed on the end face of the counterweight slider 23 facing the ice placement tank 40. This layout enables the hull simulation body to directly impact the sea ice in the ice placement tank 40 in free fall at a preset positive floating ice-breaking angle under the regulation of the magnetically controlled counterweight impact actuator 20. By adjusting the power of the drive motor 21, the magnitude of the magnetic force of the magnetic chuck 22 can be changed, thereby controlling the movement speed and acceleration of the counterweight slider 23 to precisely simulate the process of the submerged body hull simulation body 30 floating and breaking ice. In addition, this structural design of the magnetically controlled counterweight impact actuator 20 also has high flexibility and scalability. For example, by adjusting the magnetic force control of the magnetic chuck 22, complex motion control modes can be achieved to adapt to different experimental requirements. At the same time, the sliding connection method of the counterweight slider 23 also facilitates the maintenance and adjustment of the device, enabling the experimental device to quickly adapt to different experimental conditions and requirements.

[0030] In one embodiment, as Figures 1 to 2 shown, the ice load impact simulation experimental device for the submerged body in positive floating ice-breaking further includes a maintenance base frame layer 50 provided on the top of the impact base frame 10. The drive motor 21 is installed on the maintenance base frame layer 50 and connects the magnetic chuck 22 through a suspension member 24. Understandably, a connection for the suspension member 24 (suspension rope) is provided on the bottom plate at the top of the impact base frame 10 to connect the magnetic chuck 22. The magnetic chuck 22 magnetically holds the counterweight slider 23 in the working state. The setting of the maintenance base frame layer 50 facilitates the installation and maintenance of the equipment on the top of the impact base frame 10, provides a stable installation position for the drive motor 21, and also connects the magnetic chuck 22 through the suspension member 24 (such as a suspension rope) to ensure the stability of the magnetic chuck 22 during operation. The magnetic chuck 22 can firmly adsorb the counterweight slider 23 in the working state, providing reliable connection and control for the experimental process. At the same time, the presence of the maintenance base frame layer 50 facilitates the daily maintenance and repair of the drive motor 21 and the magnetic chuck 22, improving the operability and safety.

[0031] In one embodiment, if Figures 1 to 2 As shown, the ice load impact simulation experimental device for submerged body floating icebreaking further includes a sliding assembly, which includes a first guide rail column 60 and a second guide rail column 70 installed on the impact base frame 10 and on opposite sides, a first guide hole 80 provided at the first end of the counterweight slider 23, and a second guide hole 90 provided at the second end of the counterweight slider 23; the counterweight slider 23 is inserted into the first guide hole 80 through the first guide rail column 60, and the second guide rail column 70 is inserted into the second guide hole 90, so as to achieve sliding on the impact base frame 10. It can be understood that the design of the sliding assembly provides precise guidance and a stable sliding path for the movement of the counterweight slider 23 on the impact base frame 10. By symmetrically installing the first guide column 60 and the second guide column 70 on the opposite sides of the impact base 10, and respectively providing the first guide hole 80 and the second guide hole 90 at both ends of the counterweight slider 23, the counterweight slider 23 can slide smoothly and linearly along the first guide column 60 and the second guide column 70, which effectively avoids the deviation or shaking of the counterweight slider 23 during the movement, and ensures the positive floating ice-breaking angle and movement accuracy of the submersible shell simulation body 30 when it freely falls and impacts the ice layer.

[0032] In one embodiment, if Figures 2 to 3 As shown, the counterweight slider 23 includes a counterweight body 231 with a counterweight groove 232, a first flange 233 connected to the counterweight body 231 near the first guide hole 80, and a second flange 234 connected to the counterweight body 231 near the second guide hole 90. It can be understood that the first guide hole 80 is set at the first flange 233, and the second guide hole 90 is set at the second flange 234. The counterweight groove 232 opened on the counterweight body 231 allows the counterweight block to be flexibly added or removed according to experimental requirements, so as to accurately adjust the weight of the submerged shell simulation body 30 to simulate different load conditions. The first flange 233 and the second flange 234 are respectively connected to both sides of the counterweight body 231, and the first guide hole 80 and the second guide hole 90 are set thereon. These guide holes cooperate with the guide rail column on the impact base 10 to ensure that the counterweight slider 23 maintains a stable and accurate motion trajectory during the sliding process.

[0033] In one embodiment, if Figures 1 to 2As shown, the impact base 10 includes a base 11, a top plate 12, and a plurality of pillars 13 connected between the base 11 and the top plate 12. Understandably, the number of pillars 13 can be symmetrically arranged in groups between the base 11 and the top plate 12; the base 11 provides a stable bottom support for the device, and the top plate 12 is used to install and fix key components such as the magnetically controlled counterweight impact actuator 20. The pillars 13 connect the base 11 and the top plate 12, and play a role in bearing weight and maintaining the overall stability of the structure. By symmetrically arranging the pillars 13 in groups, it is possible to ensure uniform force and structural balance of the impact base 10 when subjected to impact loads, thereby effectively avoiding deformation or damage caused by uneven force.

[0034] In one embodiment, if Figures 1 to 2 As shown, the ice load impact simulation experimental device for submerged floating icebreaking also includes a crossbeam 100 connected between two adjacent pillars 13, and a plurality of evenly spaced weight-reducing holes 1001 are arranged on the crossbeam 100. It can be understood that the crossbeam 100 is connected between adjacent pillars 13, and plays a role in strengthening the overall structural rigidity of the impact base frame 10, ensuring that the device remains stable when subjected to impact loads. The plurality of evenly spaced weight-reducing holes 1001 arranged on the crossbeam 100 can, on the one hand, reduce the overall weight of the device, reduce material costs and transportation difficulties; on the other hand, the design of the weight-reducing holes 1001 will not weaken the structural strength of the crossbeam 100, but can further optimize the structural performance by reasonably distributing stress.

[0035] In one embodiment, if Figures 1 to 4 As shown, the ice load impact simulation experimental device for the submersible floating icebreaking also includes a plurality of shock-absorbing springs 110 arranged on the base 11. It is understandable that when the submersible shell simulation body 30 impacts the ice layer with a specific acceleration, especially when the impact force is too large and the ice layer deforms too violently, the two ends of the counterweight slider 23 may collide with the base 11. At this time, the shock-absorbing spring 110 group can effectively absorb and buffer this impact energy, preventing the counterweight slider 23 from directly colliding with the base 11. This buffering mechanism not only protects the counterweight slider 23 and the submersible shell simulation body 30 from damage, but also avoids potential damage to the base 11 and the entire impact frame structure, ensuring the integrity and stability of the experimental device.

[0036] In one embodiment, if Figures 1 to 2As shown, the number of the shock-absorbing springs 110 is four. The four shock-absorbing springs 110 are divided into two groups, and the two groups of shock-absorbing springs 110 are respectively arranged in one-to-one correspondence with the first flanging 233 and the second flanging 234 in the axial direction of the support column 13. Understandably, the number of the shock-absorbing springs 110 can be set according to the test requirements; during the impact process, both ends of the counterweight slider 23 are in contact with the two groups of shock-absorbing springs 110, which can effectively disperse the impact force and avoid structural damage caused by concentrated stress. At the same time, this symmetric distribution design ensures the uniformity of the shock-absorbing effect, enabling the counterweight slider 23 to maintain a stable movement trajectory when being impacted, and further enhancing the accuracy and reliability of the experiment.

[0037] In another specific embodiment, the operation process of the ice load impact simulation experiment device for the positive floating icebreaking of the submersible body is as follows:

[0038] Preparation before experiment and initial lifting: Before the experiment starts, the maintenance personnel first climb onto the maintenance base frame layer 50 to conduct a comprehensive inspection of the device to ensure that all components are operating normally. After the inspection is completed, the maintenance personnel leave the maintenance base frame layer 50. At this time, the driving motor 21 is started to energize the high-power magnetic chuck 22 to generate sufficient suction force to lift the counterweight slider 23 and the submersible hull simulation body 30. The driving motor 21 continues to rotate and lifts the submersible hull simulation body 30 along the first guide pillar 60 and the second guide pillar 70 to the specified experimental height.

[0039] Free-fall impact experiment: When the submersible hull simulation body 30 reaches the predetermined height, the operator remotely controls to switch the driving motor 21 to the non-energized mode. At this time, the suction force of the high-power magnetic chuck 22 disappears, and the counterweight slider 23 and the submersible hull simulation body 30 freely fall along the first guide pillar 60 and the second guide pillar 70 at a strictly positive floating icebreaking angle, and finally impact the sea ice in the ice placing tank 40 to generate a collision response. This process simulates the impact situation of the hull structure during the actual icebreaking process of the submersible body and completes one experiment.

[0040] Adjust the impact acceleration: If it is necessary to simulate the submersible hull simulation body 30 impacting the ice layer at a specified acceleration, the power of the high-power magnetic chuck 22 will be instantly reduced to a certain set value, and the suction force will decrease accordingly. At this time, the counterweight slider 23 and the submersible hull simulation body 30 move downward under the combined action of gravity and the remaining suction force and impact the ice layer; in this way, the icebreaking process at different accelerations can be flexibly simulated.

[0041] Adjust the load: In order to simulate the icebreaking situation under different loads, counterweight blocks can be placed in the counterweight groove 232 of the counterweight slider 23. The design of the counterweight groove 232 is reasonable and can adapt to various load conditions, so as to comprehensively simulate the icebreaking ability of the submersible body under different load conditions.

[0042] Safety guarantee mechanism: During the experiment, if the impact force is too large, causing the ice layer to deform too violently, both ends of the counterweight slider 23 will collide with the shock-absorbing spring group 110. The shock-absorbing spring group 110 can absorb the impact energy, prevent the counterweight slider 23 and the simulated fairing 30 from directly colliding with the base 11, thereby avoiding damage to the base 11 and the impact frame itself, and ensuring the safety of the experiment and the integrity of the device.

[0043] The above-described embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
