Technical Field

[0001] This invention relates to the field of detection equipment technology, specifically to a high-temperature resistant and radiation-resistant accelerometer sensor detection device. Background Technology

[0002] Accelerometers are used to measure the acceleration of an object and convert it into an electrical signal output. They are commonly used in motion analysis, attitude control, and other fields. Accelerometers consist of a mass block, damper, elastic element, and sensitive element. Based on their operating principles, they are mainly classified as piezoelectric, piezoresistive, and capacitive. High-temperature and radiation-resistant accelerometers are specifically designed for operation in harsh environments with high temperatures and radiation, and are used in aerospace, high-temperature processes, and the nuclear energy industry. Before leaving the factory, high-temperature and radiation-resistant accelerometers require testing to assess their linearity (the degree of linearity between the accelerometer output and the actual acceleration), sensitivity (the proportional relationship between the change in the accelerometer output and the change in the input acceleration), zero bias (the offset of the sensor output when there is no acceleration), and temperature characteristics (the performance of the accelerometer under different temperature conditions).

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Refer to Figures 1-8 As shown: A high-temperature resistant and radiation-resistant accelerometer testing device includes a torque detection component 100 and a dynamic detection component 200, wherein the dynamic detection component 200 is installed outside the torque detection component 100;

[0030] The dynamic detection component 200 includes an electromagnetic calibrator 209, an electromagnetic coil 210, a fixing ring 211, a device under test 212, and a contact feedback elastic element 213. A mounting frame 208 is fitted around the electromagnetic calibrator 209. The bottom of the electromagnetic calibrator 209 is connected to the device under test 212 via the electromagnetic coil 210. The contact feedback elastic element 213 is installed at the bottom of the device under test 212, and a contact mechanical feedback fixing point 219 is securely connected to the bottom of the contact feedback elastic element 213. The device under test 212... The internal assembly of the 12 is an integrated sensor group. The frame 214 is slidably connected to the internal groove of the fixing ring 211. Three sets of first rotating sections 215 are respectively connected to the surface of the frame 214. The side ends of the three sets of first rotating sections 215 are rotatably connected to second rotating sections 216. The side ends of the second rotating sections 216 are rotatably connected to third rotating sections 217. The side ends of the third rotating sections 217 are connected to feedback sensor connecting seats 218. The contact force feedback fixing point 219 and the feedback sensor connecting seats 218 form a snap-fit ​​connection.

[0031] The feedback sensor connector 218 is used to monitor the motion state of the device under test 212 in real time. The electromagnetic calibrator 209 is used to transmit electromagnetic force or control signal to realize the dynamic calibration operation of the device under test 212. The side of the frame 208 is slidably connected to a dynamic vibration cylinder 207, and the side end of the dynamic vibration cylinder 207 is slidably connected to a reciprocating cylinder 206.

[0032] A displacement seat 205 is fastened to the side end of the reciprocating cylinder 206. An X-axis displacement rail 204 is slidably connected to the side end of the displacement seat 205. A Y-axis displacement rail 203 is slidably connected to the bottom of the X-axis displacement rail 204. An auxiliary sliding groove frame is slidably connected to the side end of the X-axis displacement rail 204.

[0033] The left and right ends of the Y-axis displacement linear guide 203 are fastened with side frames 202. The bottom of the side frames 202 and the auxiliary sliding groove frame are fastened with slotted and perforated frames 201. The surface of the slotted and perforated frames 201 has through slots at both ends.

[0034] In this embodiment, firstly, the high-temperature resistant and radiation-resistant accelerometer sensor to be tested is installed inside the device under test 212. The integrated sensor group inside the device under test 212 is then powered on and preheated to ensure it is in a stable working state. Next, the electromagnetic calibrator 209 begins operation, transmitting electromagnetic force and control signals to the device under test 212 via the electromagnetic coil 210. The electromagnetic calibrator 209 contains a precise electromagnetic generator capable of producing electromagnetic force of specific intensity and direction according to a preset program and parameters. The electromagnetic coil 210 serves as both an energy transfer and signal conversion point, accurately transmitting the electromagnetic energy generated by the electromagnetic calibrator 209 to the device under test 212. Under the influence of the electromagnetic force, the device under test 212 will exhibit a certain minute displacement and change in state. The static changes reflect the response characteristics of the sensor under test under electromagnetic force. Simultaneously, the integrated sensor group within the device under test 212 sensitively senses these changes and feeds back the relevant data to the external controller. This ensures the high-precision sensing capability of the integrated sensor group can capture minute changes, providing an accurate data foundation for subsequent analysis. After receiving the feedback data, the external controller uses advanced data analysis algorithms to process it. First, it analyzes parameters such as the static sensitivity of the sensor under test. Then, it compares these parameters in detail with pre-set standard values. If a deviation is found, the external controller immediately sends a command to the electromagnetic calibrator 209, which further adjusts the electromagnetic force. The size and direction are continuously adjusted and fed back to achieve static calibration of the sensor under test, ensuring that its performance under static conditions meets strict standard requirements. Secondly, the dynamic vibration cylinder 207 and the reciprocating cylinder 206 work in synergy. The dynamic vibration cylinder 207 generates high-frequency vibration to simulate the dynamic vibration environment that may be encountered in actual applications, while the reciprocating cylinder 206 provides linear reciprocating motion, further enriching the form and range of vibration. This dynamic vibration and motion are transmitted to the electromagnetic calibrator 209 through the frame 208, and then to the device under test 212 through the electromagnetic coil 210. The frame 208 serves as structural support and vibration transmission, ensuring that the vibration can be effectively transmitted, and the electromagnetic coil 210... While transmitting vibration, it also maintains stable transmission of electromagnetic signals, enabling the tested object 212 to undergo various complex movements in a dynamic environment. Its motion reflects the actual working condition of the sensor in practical applications. The contact feedback elastic element 213 undergoes elastic deformation with the movement of the tested object 212. Due to its good elasticity and flexibility, the contact feedback elastic element 213 can accurately follow the movement of the tested object 212 and produce corresponding deformation. The contact mechanical feedback fixing point 219 engages with the feedback sensor connecting seat 218, which monitors the mechanical changes of the contact mechanical feedback fixing point 219 in real time.This allows the acquisition of motion state information of the device under test 212, including parameters such as vibration frequency, amplitude, and acceleration. This provides an important basis for comprehensively evaluating the dynamic performance of the sensor under test. The integrated sensor group inside the device under test 212 also synchronously collects the output data of the sensor under test in a dynamic environment, ensuring the comprehensiveness and accuracy of the data. The contact mechanical feedback fixing point 219 engages with the feedback sensor connecting seat 218. The feedback sensor connecting seat 218 monitors the mechanical changes of the contact mechanical feedback fixing point 219 in real time, thereby acquiring the motion state information of the device under test 212. With the cooperation of the dynamic vibration cylinder 207 and the reciprocating cylinder 206, the frame 214 is subjected to force and slides on the inner groove edge of the fixing ring 211. Then, by utilizing the rotational connection between the first rotating section 215, the second rotating section 216, and the third rotating section 217, the feedback sensor connecting seat 218 can flexibly follow the movement of the device under test 212. The system first performs static calibration to ensure accurate monitoring of the sensor's motion state. Then, an external controller collects all data from the sensor during both static calibration and dynamic testing phases, processes and analyzes it, and evaluates its performance indicators, such as sensitivity, linearity, and repeatability, by comparing the sensor's output data with standard values ​​under different environments. This combined approach of static calibration and dynamic testing comprehensively and accurately assesses the performance of the high-temperature radiation-resistant accelerometer. Static calibration ensures the sensor's basic performance under static conditions meets standards, providing a foundation for subsequent dynamic testing. Dynamic testing simulates complex vibration environments in real-world applications, allowing the high-temperature radiation-resistant accelerometer to be tested under near-real-world conditions, more accurately reflecting its performance in actual use. Through contact feedback and a data acquisition system, the system obtains real-time motion state information and output data from the sensor, providing rich and accurate data support for data analysis and evaluation.

[0035] Example 2: According to Figures 1-3 As shown, the torque detection component 100 includes a drive energy-saving operation motor 101. The side end of the drive energy-saving operation motor 101 is fastened to the surface of the support frame through a motor bracket. The output end of the drive energy-saving operation motor 101 is connected to a circumferential vibration cylinder 102.

[0036] The circumferential vibration cylinder 102 consists of a circumferential rotating frame and a swing cylinder. The swing cylinder is mounted on the surface of the circumferential rotating frame, and the circumferential rotating frame is connected to the output end of the drive energy-saving operation motor 102.

[0037] The side end of the swing cylinder is connected to an adapter plate 103, and the left and right sides of the adapter plate 103 are connected to tension adjustment connectors 104. The side ends of the tension adjustment connectors 104 are each connected to a high-strength connecting metal wire 105.

[0038] A rotating ring 106 is fastened to the side end of the high-strength connecting metal wire 105. A connecting short block 107 is symmetrically fastened to the side end of the rotating ring 106. A pi detection sensor 110 is installed on the side end of the connecting short block 107.

[0039] A sliding saddle 108 is fastened to the side end of the connecting short block 107, and a circumferential ring rail frame 109 is slidably connected to the side of the sliding saddle 108. The outer walls of the circumferential ring rail frame 109 and the support frame are fastened together.

[0040] The slotted and perforated frame 201 forms an interlocking connection with the high-strength connecting metal wire 105 through the wire slot holes.

[0041] In this example, after the high-temperature radiation-resistant accelerometer to be tested is installed on the test object 212 and the preparation work for static calibration and dynamic testing is completed, and after the dynamic testing component 200 is in operation, the drive energy-saving operating motor 101 is started. After the drive energy-saving operating motor 101 is turned on, its output end transmits power to the circumferential rotating frame of the circumferential vibration cylinder 102, causing the circumferential rotating frame to start circumferential motion. The circumferential rotating frame drives the swing cylinder mounted on its surface to perform circumferential motion, and the swing cylinder itself will generate swing motion. By combining the circumferential motion and the swing motion, the circumferential vibration cylinder 102 generates complex circumferential vibration. At the same time, the vibration is transmitted to the tension adjustment connector 104 through the adapter plate 103. The tension adjustment connector 104 plays the role of adjusting the torque transmission, so that the tension adjustment connector 104 can adjust its own tightness according to the actual testing requirements, thereby controlling the amount of torque transmitted to the high-strength connecting metal wire 105. When a larger torque is required, the tension adjustment connector 104 is tightened.When a smaller torque is required, the tension adjustment connector 104 is loosened. Then, the high-strength connecting metal wire 105 transmits the torque from the adapter plate 103 to the rotating ring 106. The rotating ring 106 begins to rotate under the torque, causing the pi detection sensor 110, mounted on the side of the connecting block 107, to detect the circumferential motion parameters of the rotating ring 106 in real time, such as angular velocity and angular acceleration. This data is then fed back to the external controller. The external controller further analyzes the performance of the sensor under different torque conditions based on this data. Simultaneously, the connecting block 107... The sliding saddle 108 at the 7th side slides on the circumferential ring rail 109, providing support and guidance for the circumferential motion of the rotating ring 106, ensuring that the rotating ring 106 can rotate stably and smoothly, reducing detection errors caused by unstable motion. The slotted and perforated frame 201 forms an interlocking connection through the wire slot hole and the high-strength connecting metal wire 105, so that the torque detection component 100 and the dynamic detection component 200 are interconnected. The dynamic vibration environment simulated by the dynamic detection component 200 will affect the torque transmission and detection results, and the torque information detected by the torque detection component 100 will also... Feedback is sent to an external controller for comprehensive evaluation of the sensor's performance under dynamic vibration and torque. This allows the sensor to be tested in conditions closer to actual use, enabling more accurate performance evaluation and reducing testing errors caused by differences between the testing environment and the actual application environment. The overall device can adjust the torque according to the characteristics and testing requirements of different sensors, making it adaptable to various types of high-temperature and radiation-resistant accelerometers, thus expanding its applicability. Furthermore, with the help of the energy-saving drive motor 101, the high-strength connecting metal wire 105 is driven to twist in conjunction with the rotating ring 106, causing the slotted and perforated frame 201 and related structures to twist as well. This allows it to work in conjunction with the dynamic detection component 2, simulating a vibration environment. This twisting action increases the complexity of the testing environment. The combination of both allows for examination of sensor performance from multiple dimensions, achieving simulation of a multi-field coupled testing environment involving vibration and torsion, enriching the testing methods and dimensions, and significantly improving the performance of the testing equipment and the accuracy of the test results.

[0042] The wiring diagrams for the energy-saving drive motor 101, the circumferential vibration cylinder 102, the tension adjustment connector 104, the pi detection sensor 110, the electromagnetic calibrator 209, and the feedback sensor connector 218 in this invention are common knowledge in the field. Their working principles are well-known technologies, and the appropriate models are selected according to actual use. Therefore, the control methods and wiring arrangements for the energy-saving drive motor 101, the circumferential vibration cylinder 102, the tension adjustment connector 104, the pi detection sensor 110, the electromagnetic calibrator 209, and the feedback sensor connector 218 will not be explained in detail.

[0043] The usage and working principle of this device are as follows: First, when the high-temperature resistant and radiation-resistant accelerometer to be tested is installed inside the device under test 212, the integrated sensor group inside the device under test 212 is powered on and preheated to reach a stable working state. The electromagnetic calibrator 209 then operates, transmitting electromagnetic force and control signals to the device under test 212 through the electromagnetic coil 210. The precise electromagnetic generator inside the electromagnetic calibrator generates electromagnetic force of specific intensity and direction according to a preset program and parameters. The electromagnetic coil realizes energy transfer and signal conversion. Under the action of the electromagnetic force, the device under test 212 produces minute displacements and state changes. The integrated sensor group senses these changes and feeds the data back to the external controller, enabling the external controller to process and analyze the data using data analysis algorithms. The static sensitivity and other parameters of the sensor under test are compared with standard values. If a deviation exists, the external controller sends a command to the electromagnetic calibrator 209 to adjust the magnitude and direction of the electromagnetic force, achieving static calibration and ensuring that the sensor's static performance meets the standard. This also enables the dynamic vibration cylinder 207 and the reciprocating cylinder 206 to work in tandem. The dynamic vibration cylinder 207 generates high-frequency vibration, and the reciprocating cylinder 206 provides linear reciprocating motion, enriching the vibration forms and range. The generated vibration is transmitted to the electromagnetic calibrator 209 through the mounting frame 208, and then to the device under test 212 through the electromagnetic coil 210. The device under test 212 moves in a complex dynamic environment, and the contact feedback elastic element 213 undergoes elastic deformation accordingly, with the contact mechanical feedback fixed point 2... 19 engages with the feedback sensor connector 218. The feedback sensor connector 218 monitors mechanical changes to obtain motion state information of the device under test 212 (such as vibration frequency, amplitude, acceleration, etc.). Meanwhile, the sensor group integrated within the device under test 212 synchronously collects the output data of the sensor under test in a dynamic environment. The dynamic vibration cylinder 207 and the reciprocating cylinder 206 cooperate to make the frame 214 slide within the fixed ring 211. Through the rotational connection of the first rotating section 215, the second rotating section 216, and the third rotating section 217, the feedback sensor connector 218 flexibly follows the movement of the device under test 212 to ensure accurate monitoring. After completing static calibration and dynamic detection preparation and the dynamic detection component 200 is in operation, the drive energy-saving operating motor 101 is started. Its output end drives the circular rotating frame of the circular vibration cylinder 102 to perform circular motion. The swing cylinder on the circular rotating frame generates a swinging motion. The combination of the two causes the circular vibration cylinder 102 to produce complex circular vibration. The vibration is transmitted to the tension adjustment connector 104 through the adapter plate 103. The tension adjustment connector 104 adjusts the tension according to the detection requirements, controlling the torque transmitted to the high-strength connecting metal wire 105. The high-strength connecting metal wire 105 transmits the torque to the rotating ring 106. The rotating ring 106 rotates under the action of torque. The pi detection sensor 110 detects its circular motion parameters (such as angular velocity, angular acceleration, etc.) in real time and feeds them back to the external controller. The external controller analyzes the performance of the sensor under test under different torques based on this.The sliding saddle 108, connected to the side end of the short block 107, slides on the circumferential track frame 109, providing support and guidance for the rotating ring 106 and reducing detection errors caused by motion instability.
