Description

Technical Field

[0001] This invention relates to the field of material mechanical property testing technology, specifically to a device for directly measuring the lift of fiber filaments through an electric field environment, which is particularly suitable for studying the electric field response characteristics of fiber materials in biomimetic robots and flexible electronic devices. Background Technology

[0002] In the field of flexible actuation and smart material design, accurately understanding the lift characteristics of fiber materials under the influence of an electric field is crucial, as it has significant implications for optimizing material performance and expanding applications. Currently, most electric force measurement methods are indirect and have obvious drawbacks: optical observation methods use high-speed cameras to capture fiber deformation and combine them with mechanical models to calculate lift, but the error rate is high; electrostatic balance methods rely on the principle of electrostatic force balance for indirect calculation, but cannot simulate dynamic electric field environments; cantilever beam sensors fix fibers to the end of a cantilever beam and use the bending deformation of the beam to infer the force value, but the sensitivity is insufficient and it is difficult to detect forces below the micronewton level.

[0003] Overall, existing technologies struggle to directly measure real-time lift under dynamic electric fields, limiting the development of related technologies. In terms of application expansion, this measurement technology holds significant value in aerospace, materials science, and biomimetic robotics. For instance, it provides test benchmarks for the surface charge accumulation protection design of Mars rovers and electric field actuation schemes for micro-bionic aircraft; it aids in the quantitative analysis of the electromechanical response characteristics of flexible piezoelectric materials and electrospun fibers in materials science; and it optimizes the design of biomimetic actuation structures in biomimetic robots, simulating the lift variation of insect wings in charged environments.

[0004] Therefore, there is an urgent need for a device that can measure the lift characteristics of fiber materials under dynamic electric field conditions. Summary of the Invention

[0012] Further, the above-mentioned electric field generating system comprises a high-voltage power supply and upper and lower electrode plates;

[0013] A distance is provided between the upper and lower electrode plates, and the distance is adjustable;

[0014] The upper electrode plate is a honeycomb-shaped insulating substrate, and a plurality of independently controlled columnar conductive cores are built-in, which extend 0-80mm in the vertical direction;

[0015] The lower electrode plate is a solid conductive plate and is connected to the high-voltage power supply.

[0016] Further, the honeycomb-shaped insulating substrate material is an alumina ceramic substrate, and the thickness is 3mm; the distance between the upper and lower electrode plates is 300-600mm.

[0017] Further, when the applied voltage is 10000V, the distance between the upper and lower electrode plates changes from 300mm to 600mm, generating a peak electric field of 15000-30000V / m.

[0018] Further, the electric field device further comprises a lifting system; the lifting system is arranged at the bottom of the lower electrode plate and is fixed by the upper electrode plate, and the distance between the upper and lower electrode plates is adjusted by adjusting the lifting mode of the lower electrode plate.

[0019] Further, the lifting system is driven by a stepping motor, and the displacement accuracy is ±0.1mm.

[0020] Further, the electric field device further comprises a distance sensor; the distance sensor is used to collect the distance data between the upper and lower electrode plates, and is also used to be linked with the high-voltage power supply to realize synchronous control of the electric field generating system.

[0021] Further, the tension measurement system adopts a micro-force sensor.

[0022] The application also provides a fiber filament lifting force test method, which is realized based on the electric field device for testing the fiber filament lifting force according to any one of the above-mentioned methods.

[0023] Step S1: One end of the electrostatic fiber filament is fixed to a micro-force sensor, and the other end is freely suspended between the electrodes;

[0024] Step S2: when the fiber length is greater than 400 mm, the lifting system is controlled to lower the lower electrode plate to the lowest position;

[0025] Step S3: a 10000V high-voltage power supply is applied, and the electric field intensity is detected, and if the deviation is greater than 5%, the voltage is automatically adjusted for compensation;

[0047] The specific embodiments of the present application will be further described in conjunction with the drawings.

It should be noted that for those skilled in the art, without departing from the concept of the present application, a number of changes and improvements can be made, which are within the scope of protection of the present application.

[0048] Embodiment one, this embodiment proposes a high-precision, multi-scene compatible fiber filament lift force test electric field device, which is designed to solve the direct measurement problem of micro-newton level lift force in dynamic electric field environment. The device includes an electric field generating system, a tension measuring system, an electric field sensor, and an electric field shielding shell;

[0049] The electric field generating system is used to provide a stable and adjustable electric field environment to provide the electric field force source necessary for the fiber filament to generate lift;

[0050] The fiber filament is fixed at one end to the tension measuring system, and the other end is freely suspended in the electric field generating system;

[0051] The electric field sensor is used to measure the electric field intensity in the electric field generating system through a redundant arrangement;

[0052] The electric field shielding shell is used to isolate external electromagnetic interference and constrain the internal electric field to prevent leakage, while protecting the internal components from dust and debris.

[0053] This embodiment analyzes the typical intensity of the Martian atmosphere electric field, specifically: under normal circumstances, it is usually less than 1,000 V / m. Under sandstorm environment, it can reach 20,000 V / m, but cannot form large-scale lightning. Therefore, the working range of the electric field generating system designed in this embodiment is 0-20kV / m, which meets the Martian atmosphere electric field conditions.

[0054] The electric field device designed in this embodiment realizes the accurate simulation and real-time measurement of the typical electric field of Mars atmosphere (0-20kV / m) through the cooperative design of modular electric field generating system, self-adaptive lifting module and high-sensitivity sensing technology, while supporting the dynamic regulation of local non-uniform electric field, providing an innovative experimental platform for the material performance test of bionic robots and flexible electronic devices.

[0055] Embodiment two, see Figures 1 to 8The embodiment is used for testing the electric field device for the fiber filament lift force, and is a specific description of the electric field device for testing the fiber filament lift force provided in Embodiment One;

[0056] As shown in Figure 1 , the electric field generating system includes a high-voltage power supply and upper and lower electrode plates; a distance is provided between the upper and lower electrode plates, and the distance is adjustable; the upper electrode plate 1 is a honeycomb-shaped insulating substrate, and a plurality of independently controlled columnar conductive cores 9 are built-in, which extend 0-80 mm in the vertical direction; the lower electrode plate 5 is a solid conductive plate and is connected to the high-voltage power supply.

[0057] The electric field generating system designed in the above embodiment mainly functions to generate a stable and adjustable electric field environment in the device, to provide the fiber filament 3 with the electric field force source necessary for generating lift force, to flexibly regulate and control the intensity, direction and other characteristics of the electric field by changing the output voltage of the power supply, the electrode spacing and other parameters, and to further study the influence of different electric field conditions on the fiber filament lift force. In actual application, the upper and lower electrode plates can be arranged at appropriate spatial positions according to experimental requirements to form a specific electric field distribution pattern. Among them, a plurality of honeycomb-shaped holes are provided in the middle of the upper electrode plate 1 for inserting a plurality of independently controlled columnar conductive cores 9, as shown in Figure 2 . The lower electrode plate 5 is made of a solid copper plate, which is a solid conductive plate. The spacing between the upper and lower electrode plates can be adjusted in the range of 300-600 mm. When the applied voltage is 10000 V, the distance between the two electrode plates changes from 300 mm to 600 mm, and by performing electric field simulation, as shown in Figure 3 , it can be seen that a peak electric field of 15000-30000 V / m can be generated, which meets the electric field range of about 20000 V / m of the Martian atmosphere.

[0058] Further, the electric core 9 can extend 0-80 mm in the vertical direction. Since each electric core 9 can independently extend from the upper electrode plate, as shown in Figure 4 , a locally enhanced non-uniform electric field is created. By extending the local electrode by 50 mm, the electric field intensity in the target area is increased by more than 60%, and by Figure 5 the simulation diagram of the locally enhanced non-uniform electric field, it is verified that the distributed electrode scheme can realize the excitation of the locally enhanced electric field.

[0059] Further, the overall shape of the electric core 9 is a regular hexagon with a cross-sectional area of 10 mm high and a length of 100 mm, and the material is pure copper, as shown in Figure 6 .

[0060] Further, the upper electrode plate 1 material adopts an alumina ceramic plate with good insulation properties as the first insulation layer to isolate adjacent battery cells. The thickness of the ceramic plate between the battery cells is 3 mm, which can effectively prevent the influence of the electrode on each other when the electrode is independently powered and prevent breakdown.

[0061] Further, the high-voltage power supply output range is 0-20 kV, connected to the lower electrode plate, and the high-voltage power supply can provide adjustable high-voltage output.

[0062] The present embodiment avoids the risk of high-voltage breakdown of adjacent battery cells by designing the ceramic substrate thickness to be 3 mm and combining a honeycomb isolation structure to achieve anti-interference and stability design of the upper electrode plate.

[0063] As shown in Figure 1 , the tension measurement system is implemented using a micro-force sensor 4. The MEMS micro-force sensor 4 is fixed inside the upper electrode plate and directly contacts the fiber filament sample 3. In actual application, one end of the fiber filament 3 with static electricity is fixed to the micro-force sensor 4, and the other end is freely suspended between the upper and lower electrode plates.

[0064] Further, the MEMS micro-force sensor has a range of 0-10 N and a minimum graduation value of 0.1 μN. It can directly capture μN-level lift, with an accuracy improvement of two orders of magnitude compared to traditional optical measurement methods.

[0065] As shown in Figure 1 , the distance sensor 7 is arranged on the lower electrode plate 5 to collect distance data between the upper and lower electrode plates.

[0066] As shown in Figure 1 , the electric field sensor 8 measures the electric field strength in the electric field generation system through a redundant arrangement to detect whether the electric field strength reaches the preset value. The principle of the electric field sensor is shown in Figure 7 .

[0067] The present embodiment realizes real-time feedback of electric field distribution data by arranging two pairs of electric field sensors 8 (error ±1%) symmetrically left and right, thereby achieving double-path verification of electric field strength. When the deviation of the two-path data is >5%, the power supply is automatically cut off to prevent the risk of partial discharge.

[0068] As shown in Figure 1 , the electric field shielding shell 2 is used to isolate external electromagnetic interference and constrain the internal electric field to prevent leakage and protect the internal components from dust and debris.

[0069] Further, the electric field shielding shell 2 is made of aluminum plate with a thickness of 3 mm; the electric field shielding shell 2 has the following functions: operator protection: the shielding layer limits the internal high-voltage electric field in the cavity, ensuring that the electric field intensity in the operating area is below the upper limit of safety. Anti-breakdown redundancy: the shell forms a double insulation barrier with the internal ceramic substrate (alumina), reducing the risk of high-voltage breakdown. Preventing the internal high-voltage electric field of the device from radiating outward, avoiding interference with surrounding precision instruments. The shielding effect is as shown in Figure 8 .

[0070] This embodiment avoids the risk of high-voltage breakdown of adjacent battery cells by designing the upper electrode plate of the ceramic substrate material to be 3 mm thick, combined with the honeycomb isolation structure; at the same time, the double insulation barrier formed by the aluminum shell electric field shielding shell can reduce the risk of breakdown to <10^-6 times / hour. Ceramic-metal composite barrier: the alumina ceramic substrate (dielectric strength 30 kV / mm) and the aluminum shell (ground) form a double insulation layer, which can withstand a field strength of 50 kV / m for 100 hours without breakdown.

[0071] Embodiment three, see Figure 1 This embodiment is described in the above embodiment two, which is an electric field device for testing the lifting force of fiber filaments with a lifting system 6;

[0072] As shown in Figure 1 , the lifting system 6 is arranged at the bottom of the lower electrode plate 5 and is fixed by the upper electrode plate 1. The lifting system 6 adjusts the distance between the upper and lower electrode plates by adjusting the lifting mode of the lower electrode plate 5.

[0073] In actual application, the lifting system is driven by a stepping motor with a displacement accuracy of ±0.1 mm. The distance between the upper and lower electrode plates can be adjusted in the range of 300-600 mm, supporting fiber testing of 50-600 mm (such as simulating insect wing cilia of 50-100 mm, and biomimetic flapping wing fibers of 300-500 mm).

[0074] Embodiment four, a test method realized by the electric field device for testing the lifting force of fiber filaments based on the above-mentioned embodiments, the test method is:

[0075] Step S1: one end of the electrostatic fiber filament is fixed to a micro-force sensor, and the other end is freely suspended between the electrodes;

[0076] Step S2: when the fiber length is >400 mm, control the lifting system to lower the lower electrode plate to the lowest position;

[0077] Step S3: apply a 10000V high-voltage power supply and detect the electric field intensity. If the deviation is >5%, automatically adjust the voltage compensation;

[0078] Step S4: The micro-force sensor continuously records the lift value, and synchronously saves the time-lift curve, real-time field intensity, and electrode plate spacing data.

[0079] Step S5: The control electrode core is extended by 50 mm, the local electrode spacing is shortened to 250 mm, the field intensity is increased, and the lift difference of the fiber in the conventional area and the enhanced area is measured under the same global field intensity.

[0080] In actual application, the embodiment is specifically:

[0081] Basic measurement process:

[0082] One end of the electrostatic fiber filament is fixed to the micro-force sensor, and the other end is freely suspended between the electrodes.

[0083] Further, when the fiber length is greater than 400 mm, the lower electrode plate is lowered to the lowest position (spacing 600 mm) by controlling the lifting system.

[0084] Further, the electric field loading: adjust the electrode spacing to 300 mm to apply high-voltage power supply (10000V).

[0085] Further, if the field intensity deviation is greater than 5%, the voltage is automatically adjusted for compensation.

[0086] Further, the micro-force sensor continuously records the lift value, and synchronously saves the time-lift curve, real-time field intensity, and electrode plate spacing data. Sample installation: the fiber filament (itself charged), one end is fixed on the micro-force sensor, and they are placed in the device together.

[0087] Further, adjust the lifting system to adapt to different length fiber filaments, and measure the electrode plate spacing through the distance sensor.

[0088] Local electric field enhancement test:

[0089] Select the upper electrode plate specific columnar electrode core to extend the appropriate distance on the control interface.

[0090] Further, control the selected electrode core to extend 50 mm, so that the local electrode spacing is shortened to 250 mm, corresponding to the field intensity increase.

[0091] Further, under the same global field intensity, the lift difference of the fiber in the conventional area and the enhanced area is measured.

[0092] The application provides a stable and adjustable electric field environment by an electric field generating system, and provides a source of electric field force necessary for the fiber filament to generate lift. The electric field generating system comprises a high-voltage power supply and upper and lower electrode plates. By adjusting the distance between the upper and lower electrode plates, a peak electric field of 15000-30000 V / m can be generated, which meets the electric field range of about 20000 V / m of the Martian atmosphere electric field. Meanwhile, a plurality of honeycomb holes are formed in the middle of the upper electrode plate for inserting a plurality of independently controlled columnar conductive cores, and the cores can be extended by 0-80 mm in the vertical direction. Since each core can be independently extended from the upper electrode plate, a locally enhanced non-uniform electric field is created. By extending the local electrode by 50 mm, the electric field intensity of the target area is increased by more than 60%, and it is verified that the distributed electrode scheme can realize the excitation of a locally enhanced electric field.

[0093] Further, the application adjusts the distance between the upper and lower electrode plates through a lifting system, and realizes two-dimensional freedom adjustment of the electrode distance and field intensity control in combination with the independent core control in the upper electrode plate.

[0094] In summary, the application discloses a high-precision and multi-scene compatible fiber filament lift test electric field device, which is designed to solve the problem of direct measurement of micro-newton level lift in a dynamic electric field environment. Through the cooperative design of the modular electric field generating system, the self-adaptive lifting module and the high-sensitivity sensing technology, the device realizes accurate simulation and real-time measurement of the typical electric field (0-20 kV / m) of the Martian atmosphere, and supports dynamic regulation of the local non-uniform electric field, thereby providing an innovative experimental platform for the material performance test of bionic robots and flexible electronic devices.
