Description

Technical Field

[0001] The present invention relates to the technical field of airborne radars, and in particular to a method for constructing an electromechanical platform of a radar complete machine environment test tooling. Background Art

[0002] The batch production task of a certain airborne fire control radar is heavy, and the reliability, practicality and applicability of the quality of batch production test fixtures are particularly important. In the batch production test of the whole machine, the radar whole machine test involves multiple projects including whole machine stress, temperature and humidity, vibration test, etc. The fixture is responsible for the continuous test of the whole machine for nearly 90 days. The yield, fatigue resistance and compatibility of the fixture with the adapter installation are also issues that cannot be ignored. Due to the special system characteristics of airborne radar, the design of the fixture follows the principles of light weight, strong rigidity, and maximizing the low-order natural frequency. Usually the fixture structure is eclectic and has no fixed form. The cast fixture has good mechanical properties. The manufactured fixture is verified according to the relevant provisions of GJB 150A-2009 "Military Equipment Laboratory Environmental Test Method". Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention provides a method for assembling an automatic erection and leveling tool for a whole machine by designing a mechatronic mechanical device with certain functions, and uses a four-point method to combine and debug the working state of the whole machine test fixture by using an electromechanical mechanical device to improve the compatibility and linkage of the whole machine configuration fixture, so as to extend the service life of the radar whole machine tooling fixture by improving the practicability and reliability of the radar fixture.

[0004] The purpose of the present invention is achieved through the following technical solutions.

[0005] A method for constructing a radar whole machine environmental test tooling electromechanical platform, the steps comprising: structure definition, tooling surveying and mapping, electromechanical structure analysis, platform process improvement and experimental process control.

[0006] Define value with the concept of efficient whole-machine electromechanical erection platform; propose a process framework, define improvement projects in combination with tools, and integrate tooling surveying and mapping technology into the technical solution design during the measurement phase; in the analysis phase, use the principle of combining whole-machine fixtures and mechanical automatic erection systems to identify structural parts of the tooling platform, screen data and conduct rational verification; in the improvement phase, the main theme is flow and pull principles, and various conditional modes in the test are used to add, rearrange, delete, simplify and merge design modules, while improving the robustness and process capability of the specific test workflow; in the control phase, in addition to processing the control system content of the whole-machine environmental test tooling platform, the new problems described in the implementation should also be summarized to improve the next test process verification.

[0007] The structural definition in the scheme is manifested in macro and micro. At the macro level, it is necessary to interpret the experimenter, key quality factors, process control and graphic analysis. The entire experiment requires the experimenter to have the corresponding theoretical knowledge of the automated electromechanical lifting and leveling device, understand the needs of the objects served by the tooling platform, and explore its marketing value. The key quality factors are determined by the experimenter's technical energy conversion and product function quantification; the focus of the scheme is on the key quality factors. The concept of selecting the base of the whole machine tooling is based on the electromechanical system determined by the tonnage of the whole machine of the airborne product, and the feedback of the electromechanical control circuit is also particularly important; in the process control, it is necessary to grasp the principle of first tooling system verification and then whole machine embedded verification, and decompose the workflow according to the process layer by layer; graphic analysis refines the items, and quantifies the construction plan from the basic lifting stroke circuit to the electromechanical leveling system and then to the whole machine tooling work test. The mechanical modal analysis data is the reliability function demonstration of the fixture. At the micro level, the provider needs to input the relevant original fixture parameters as the basic data for the fixture platform design, and initiate the workflow as the basis for the experimenter to verify the working parameters of the electromechanical tooling platform.

[0008] The fixture surveying and mapping is a detailed surveying and mapping of the test fixtures, starting with the basic fixture size measurement. The bolt holes of the positioning plate in the fixture are fixed to the comprehensive test platform and the mechanical vibration platform. The size, thickness and alloy material of the positioning plate, the weight of the whole platform and the mechanical platform, the size fixing points of the electromechanical automatic lifting system, and the position of the force points of the product fixture installation all need to be measured and located. The surveying and mapping of the fixture requires both data measurement and chart drawing. The fixture and mechanical platform structure need to be integrated into a whole for size measurement and transfer to various condition test benches.

[0009] The electromechanical structure analysis module starts with the basic electromechanical control circuit. Identifying the electromechanical platform of the tooling essentially requires verifying the yield, tensile strength, impact resistance of the fixture platform and the performance of the airborne equipment in the use load environment; screening out tooling with high natural frequency, good transfer characteristics, uniform response at each point on the connection surface, small waveform distortion, and good energy reduction amplification performance; verifying whether the integrated fixture can still meet the requirements under more stringent conditions, and simulating and analyzing the stress distribution to obtain the ultimate stress under the simulated working conditions.

[0010] The process improvement of the platform incorporates the electromechanical control lifting stroke and leveling system on the basis of the original fixture. Through experiments, materials are screened one by one, and the appropriate processing technology for alloy materials with large damping is selected; the signal communication transfer function is quantified to optimize the functional parameters of the tooling platform; the optimization work module is reflected in the mechanical height adjustment and leveling and the connection between each test turntable, so as to improve the plasticity of the stress work of the whole platform; so that the experimental design work of the tooling fixture platform can be carried out steadily.

[0011] The experimental process control mainly involves formulating experimental control plans, establishing control targets, measuring actual performance, variance analysis, and deviation correction. To eliminate the waste of design costs, the cost is analyzed and calculated through a large amount of earned value analysis and performance evaluation data of personnel participating in the experiment. At the end of the experimental project, a test report is generated to conduct a credibility analysis.

[0012] The implementation of the entire system architecture plan is based on the design life cycle of the environmental test tooling electromechanical platform, equipped with detailed program materials. The organizational process follows the experimental outline process and the process specifications of the tooling fixture design to coordinate work, innovate and eliminate waste, and finally push and publish the test results, and provide feedback on the electromechanical platform fixture design experiment project plan.

[0013] Compared with the prior art, the advantages of the present invention are: the present invention realizes the mechatronic function of the whole machine fixture platform through the electromechanical stroke lifting and leveling system. The electromechanical system is added on the basis of the original fixture, and the data is transmitted and processed through the main controller, and the human-computer interaction platform realizes the installation of the whole machine fixture. The construction of the airborne stable platform has the advantages of balanced tooling pressure, high production efficiency, convenient assembly, good compatibility, good vibration resistance, good impact performance, and a wide range of ambient temperature.

[0025] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] A method for constructing a radar whole machine environmental test tooling electromechanical platform, the steps comprising: structure definition, tooling surveying and mapping, electromechanical structure analysis, platform process improvement and experimental process control.

[0027] Define value with the concept of efficient whole-machine electromechanical erection platform; propose a process framework, define improvement projects in combination with tools, and integrate tooling surveying and mapping technology into the technical solution design during the measurement phase; in the analysis phase, use the principle of combining whole-machine fixtures and mechanical automatic erection systems to identify structural parts of the tooling platform, screen data and conduct rational verification; in the improvement phase, the main theme is flow and pull principles, and various conditional modes in the test are used to add, rearrange, delete, simplify and merge design modules, while improving the robustness and process capability of the specific test workflow; in the control phase, in addition to processing the control system content of the whole-machine environmental test tooling platform, the new problems described in the implementation should also be summarized to improve the next test process verification.

[0028] The structural definition is manifested in macro and micro. At the macro level, it is necessary to interpret the experimenter, key quality factors, process control and graphic analysis. The entire experiment requires the experimenter to have the corresponding theoretical knowledge of the automated electromechanical lifting and leveling device, understand the needs of the objects served by the tooling platform, and explore its marketing value. The key quality factors are determined by the experimenter's technical energy conversion and product function quantification; the focus of the plan is reflected in the key quality factors. The concept of selecting the base of the whole machine tooling is based on the electromechanical system determined by the tonnage of the whole machine of the airborne product, and the feedback of the electromechanical control circuit is also particularly important; in the process control, it is necessary to grasp the principle of first tooling system verification and then whole machine embedded verification, and decompose the workflow according to the process layer by layer; graphic analysis refines the items, and quantifies the construction plan from the basic lifting stroke circuit to the electromechanical leveling system and then to the whole machine tooling work test. The mechanical modal analysis data is the reliability function demonstration of the fixture. At the micro level, the provider needs to input the relevant original fixture parameters as the basic data for the fixture platform design, and initiate the workflow as the basis for the experimenter to verify the working parameters of the electromechanical tooling platform.

[0029] The fixture surveying and mapping is a detailed surveying and mapping of the test fixtures, starting with the basic fixture size measurement. The bolt holes of the positioning plate in the fixture are fixed to the comprehensive test platform and the mechanical vibration platform. The size, thickness and alloy material of the positioning plate, the weight of the whole platform and the mechanical platform, the size fixing points of the electromechanical automatic lifting system, and the position of the force points of the product fixture installation all need to be measured and located. The surveying and mapping of the fixture requires both data measurement and chart drawing. The fixture and mechanical platform structure need to be integrated into a whole for size measurement and transfer to various condition test benches.

[0030] The electromechanical structure analysis module starts with the basic electromechanical control circuit. Identifying the electromechanical platform of the tooling essentially requires verifying the yield, tensile strength, impact resistance of the fixture platform and the performance of the airborne equipment in the use load environment; screening out tooling with high natural frequency, good transfer characteristics, uniform response at each point on the connection surface, small waveform distortion, and good energy reduction amplification performance; verifying whether the integrated fixture can still meet the requirements under more stringent conditions, and simulating and analyzing the stress distribution to obtain the ultimate stress under the simulated working conditions.

[0031] The process improvement of the platform incorporates the electromechanical control lifting stroke and leveling system on the basis of the original fixture. Through experiments, materials are screened one by one, and the appropriate processing technology for alloy materials with large damping is selected; the signal communication transfer function is quantified to optimize the functional parameters of the tooling platform; the optimization work module is reflected in the mechanical height adjustment and leveling and the connection between each test turntable, so as to improve the plasticity of the stress work of the whole platform; so that the experimental design work of the tooling fixture platform can be carried out steadily.

[0032] The experimental process control mainly involves formulating experimental control plans, establishing control targets, measuring actual performance, variance analysis, and deviation correction. To eliminate the waste of design costs, the cost is analyzed and calculated through a large amount of earned value analysis and performance evaluation data of personnel participating in the experiment. At the end of the experimental project, a test report is generated to conduct a credibility analysis.

[0033] The implementation of the entire system architecture plan is based on the design life cycle of the environmental test tooling electromechanical platform, equipped with detailed program materials. The organizational process follows the experimental outline process and the process specifications of the tooling fixture design to coordinate work, innovate and eliminate waste, and finally push and publish the test results, and provide feedback on the electromechanical platform fixture design experiment project plan.

[0034] The mechanical structure platform of the airborne radar ring test fixture uses a mechatronic mechanical device with directional functions. It exists as the basic system of the radar fixture and provides automatic erection and leveling of the whole machine experimental fixture platform. The N-order modal performance analysis of the whole machine assembly fixture is carried out under the three-coordinate mechanics conditions. Under the condition of the airborne equipment functional impact load, the maximum stress of the fixture and the impact of all directions, the safety factor and structural design strength can meet the requirements. Through the stress distribution, the comprehensive fixture can still meet the requirements under harsh conditions. The center of mass of the designed fixture is reduced, the natural frequency is increased, and the performance is good.

[0035] The test platform design is based on the core concept of DMAIC, and implements the "Define-Measure-Analyze-Improve-Control" process, proposing a process framework for each stage of tooling design; measuring the current status of process management; analyzing the variation phenomenon in the test to save manpower and material resources; in the improvement stage, proceed step by step according to the flow of the tooling erection test process; in the control stage, summarize and improve the problems caused by the implementation of the tooling erection.

[0036] The purpose of the whole machine tooling casting fixture is to reduce the weight of the radar structure, enhance the material hardness and achieve lightweight. The alloy ratio in the alloy material enhances the hardness and is suitable for airborne aerospace products.

[0037] The platform's basic lifting columns are fully automatic motor-driven, reflecting the high precision of the carrier's stable platform.

[0038] The four-point support architecture pattern is combined to obtain four surfaces, a closed-loop system with two related quantity inputs and four related quantity outputs.

[0039] The multi-point support structure leveling device is mainly used in airborne military platforms. It has the advantages of high efficiency, load-bearing capacity matching, simple transmission, etc., and has obvious advantages in the field of airborne platform leveling.

[0040] The incorporation of an electromechanical lifting mechanism improves the load-bearing operation of the structure.

[0041] The dual-axis horizontal sensor of the leveling system is installed on the working plane. The main controller logic circuit applies the CAN line interface protocol and other functions to realize data processing and communication functions, and adjust the height of the four supporting points of the working plane to complete the one-key leveling function of the whole machine test tooling.

[0042] The mechanical properties of the casting fixture fully meet the regulations of GJB 150A-2009 "Laboratory Environmental Test Methods for Military Equipment".

[0043] The safety factor of the tooling is verified through mechanical N-order modal analysis.

[0044] According to the manufacturing process specifications, integral casting is adopted, followed by welding and screwing, and the complex curved surface or variable thickness and variable cross-section fixture is cast and produced.

[0045] The stable platform technology of airborne radar has been widely valued in the field of radar application and research, and radar special electromechanical devices have been fully and rapidly developed.

[0046] Example

[0047] The design of the electromechanical erection platform for a certain type of PD radar complete machine environmental test tooling is based on the product project life cycle, with a detailed electromechanical platform implementation plan, and the old fixtures are upgraded to realize the mechatronic test tooling platform. Figure 1 The experimental platform architecture shown is based on the DMAIC concept and incorporates electromechanical construction technology to significantly improve quality.

[0048] Step 1: According to the laboratory management regulations and product test specifications, select the environmental test equipment suitable for the whole machine test of the airborne radar model, that is, the equipment in the whole machine comprehensive test box and the vibration test area. According to the comprehensive test box table position and environmental test vibration table hole size diagram issued by the laboratory, select the tooling positioning plate for the whole machine test. The installation restrictions of the entire electromechanical tooling, including weight and distance, should be within the load-bearing range of the vibration table and maintain a certain safety distance from surrounding objects during installation. For details on the installation position of the positioning plate fixture, see Figure 2 The size of the positioning plate is larger than the size of the fixture base of a certain model product for easy fixation. The special body fixture base of the airborne radar is made of aluminum alloy, and the bottom whole machine tooling pressure plate is usually made of steel plate and aluminum alloy plate. The specific material model coefficient is shown in Figure 6. The weight of aluminum alloy is only 1 / 3 of that of steel, which meets the quality requirements of airborne radar structure. The hardness of aluminum alloy is increased by the alloy ratio of aluminum in aluminum alloy. At present, the commonly used aluminum alloy materials for airborne aerospace products are 7075 (T6), 7A04 and 7079 (T73). Its elastic modulus, Poisson's ratio, density, tensile strength and yield strength are better than other alloy materials, achieving lightweight quality while meeting the hardness requirements. The hole size of the positioning plate refers to the hole opening of the table of the laboratory whole machine test equipment. The connection hole of the plate fixture and the vibration table is generally screwed with countersunk holes. It is implemented according to the structural process specifications. The step height at the countersunk hole is about 20 to 25 mm. The height of the same fixture is kept consistent, and the hole position of the vibration table installation surface is fully utilized to ensure the connection stiffness between the fixture and the vibration table. When used for high-frequency (2000HZ) testing, the spacing between the bolts shall not exceed 8cm, the fixture screw hole shall adopt coarse thread, and the connection screw hole shall adopt hard thread bushing or steel wire thread sleeve. The form and number of connection holes on the positioning plate should be consistent with the number of screw holes for assembly reinforcement at the bottom of the complete fixture. The number of platform fastening bolts should be installed in accordance with the laboratory fixture installation specifications. The number of screw connections should not be too much and should be controlled within the fixed safety range to reduce the "burr" phenomenon in the high-frequency band during the ring test. Considering that the horizontal slide of the vibration table is soft and easy to deform, the contact surface between the positioning plate and the slide should be less than 0.1mm / M. The positioning plate as the base of the tooling should be as small as possible, and the integrated center of gravity with the complete platform should be as low as possible.

[0049] Step 2: Set up the electromechanical platform on the positioning plate. The construction of the electromechanical platform is carried out in two steps.

[0050] (1) First, four electromechanical lifting columns are fixed on the positioning plate according to the four-point principle of the structural support column. The lifting column is divided into three parts: the column part, the control system and the power system. In terms of power control, based on the weight requirements of the airborne radar, the main choice is an electromechanical fully automatic lifting system, and the column is driven by the motor built into the column. The display control box sends a command signal to the control system, which then processes the signal through the PLC programmable logic circuit. According to the command, the relay is controlled to be closed or disconnected to start the power unit motor and realize the motor-driven column lifting. When the object approaches the sensing surface of the switch to the action distance, no mechanical contact or pressure is required to drive the function, thereby providing instructions to the PLC device. According to the individual circuit characteristics of the lifting column ( Figure 5 ) It can be seen that the stroke detection and locking functions are essential to realize the lifting of the column. The four columns are fixed on the positioning plate fixture according to the dimensions of the product structure tooling drawing. Then proceed to detect the signal communication function between the four support points ( Figure 4), the main controller is responsible for data transmission and processing, the CAN bus receives the information received by the data acquisition node, organizes and stores it in the dual-port RAM according to the protocol. The interface circuit usually uses a transceiver for RS485 or RS422 communication, which is composed of receiving and driving circuits to achieve error-free data transmission. Information is transmitted through the human-computer interaction platform, and a display control box is usually selected as an external control device to realize the function;

[0051] (2) After the four columns are installed and fixed, the whole machine fixture is mounted on the column support points and the reinforcement bolts are positioned according to the hole positions. A two-axis horizontal sensor is assembled and installed on the working plane. By adjusting the height of the four support points of the working plane, the horizontal sensors of the two axes are parallel to the horizontal plane. The electronic equipment platform is in a horizontal state, and the support points confirm the landing point. The four fulcrums are combined to obtain a closed-loop control system with four surfaces, two related quantity inputs, and four related quantity outputs. The test platform leveling system is debugged to orthogonalize the structure. The four support points of the orthogonal components of the spirit level are arranged in a rectangle, and the spirit level is placed in a posture parallel to the line connecting the two adjacent points of the support point. The transfer function block diagram of the experimental platform leveling system is shown in Figure 3 ,Through decomposition, speed regulation and lifting synchronization technology, the characteristics of the motor support mechanical mechanism on the same component remain consistent;

[0052] Step 3: After the main structure of the electromechanical tooling platform is completed, the whole machine unit is embedded to perform the whole machine tooling electromechanical lifting and leveling test. During the test, refer to step 2 to set up the lifting and leveling operation, use the external display and control box to realize the one-key leveling function of the whole machine tooling, and observe the accuracy value of each axis of the level to realize the leveling of the whole machine tooling. The leveling accuracy of the domestic electromechanical leveling system is about 1', and the maximum load of a single support mechanism is 8×104N. The electromechanical actuator is suitable for lightweight radars.

[0053] The whole machine electromechanical automatic leveling adopts electromechanical driven mechanical transmission to achieve horizontal debugging, which is composed of a supporting structure, a control unit, a horizontal sensor system, a measurement and control device, and interconnecting cables. Its characteristics are that the actuator is small in size, large in load, high in follow-up accuracy, accurate in locking position, and sensitive in lifting detection sensor device; the actuator is randomly composed of an electromechanical synchronous gear train, which has a wide speed adjustment performance, support point monitoring function, accurate leveling performance and system safety protection function. The electromechanical automatic leveling system has high driving efficiency, and the support column is an independent power unit. Therefore, under the same load capacity and leveling time requirements, the electromechanical system itself has a relatively smaller mass and volume, and the length of the electromechanical support column in the same stroke state is relatively larger. The electromechanical leveling system has high efficiency and simple transmission, and is suitable for use on aircraft carrier tooling platforms.

[0054] The whole machine tooling design of the present invention is based on the electromechanical stroke lifting and leveling assembly to match the product base and the test machine, so as to realize the adaptive adjustment function of the whole machine electromechanical tooling platform. The stable platform is constructed as a radar installed on a moving carrier, and the airborne radar will have the problem of antenna pointing stability. The electromechanical four-axis stable platform overcomes the swaying of the carrier, that is, no matter how the carrier sways, the inner frame is always in a horizontal position. The electromechanical stable platform has good vibration and impact resistance and a wide range of ambient temperature. This radar tooling structure is simple, pressure is balanced, production efficiency is high, positioning is accurate, and assembly is convenient. The platform has strong compatibility and can be used as a reference for lightweight radar tooling.
