Description

Technical Field

[0001] The utility model relates to the technical field of aircraft engine testing, and more specifically to an intelligent control glove used for aircraft engine virtual testing. Background Art

[0002] At present, the design process of the test plan for aircraft engine components is mainly based on the traditional two-dimensional lead diagram and three-dimensional solid model to carry out preliminary planning and design modification of the test lead path. Subsequently, a strength check is carried out to determine the feasibility of the modification plan. For modification plans that do not meet the strength requirements, multiple iterative modifications are required until the design plan is finally implemented on site. This process is not only cumbersome and time-consuming, but also due to factors such as different operators, differences in the processes and tools used, and dimensional judgment errors, the test line may not be laid out as planned, which in turn leads to a series of problems such as temporary changes to the test project, failure to achieve test goals, and extended trial production cycles.

[0003] Virtual reality technology, with its three major features of immersion, interactivity and imagination, is gradually changing the face of many traditional industries. In the field of aircraft engine testing, virtual reality technology has also shown great application potential. By building a virtual reality environment, the parameter measurement scheme design process of aircraft engine components can be interactively and immersively simulated to obtain the most optimized test design scheme, which can solve the problems existing in the current test scheme design process, shorten the design cycle, improve the efficiency of test implementation, and thus accelerate the research and development process of model engines.

[0050] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0051] In the description of this specification, the descriptions referring to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples", etc., mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0052] For the parameter measurement of the rotating components of an aero-engine, including key parameters such as stress, temperature, and pressure, traditional technologies generally rely on contact measurement methods. This method collects data through sensors and transmits the data to a dedicated data acquisition system for processing via leads.

[0053] The utility model proposes an intelligent control glove specially used in the engine virtual reality environment. Through the design and processing of the development parts group of the intelligent control glove, and the assembly with simple common parts such as gloves, steering gears, encoders, etc., a customizable intelligent control simulation hand system is formed.

[0054] During the design phase, we paid special attention to the planning and simulation of the parameter measurement lead path. We built a three-dimensional simulation environment and loaded the engine model into it. We tracked the motion trajectory of the smart control glove in real time in the simulation environment, and verified the rationality and effectiveness of the lead solution through simulation operations.

[0055] Figure 1 A schematic diagram of a component assembly of an intelligent control glove for virtual testing according to an embodiment of the utility model is disclosed, such as Figure 1 As shown, the utility model proposes an intelligent control glove for virtual testing of aircraft engines, including a glove body, a fingertip fixing part 1, a joint fixing part 2, a fixing clamping part 3, a track line slide rail part 4 and a finger track line 5:

[0056] The fingertip fixing part 1 is arranged on the fingertips of the glove body;

[0057] The joint fixing part 2 is arranged at the middle joint of the glove body and is used to limit and guide the twitching direction of the trajectory line;

[0058] The track line slide rail part 4 is installed on the fixed clamping part 3 and is used to retract and release the track line according to the bending of the finger;

[0059] The fixed clamping part 3 is arranged at the root of the glove body and is used to install the tactile feedback actuator and sensor;

[0060] The tactile feedback actuator is used to provide force feedback, and the sensor is used to measure the position or angle information of the finger. The combination of these two types of components can achieve accurate force feedback and control functions;

[0061] The finger trajectory line 5 is fixedly connected to the fingertip fixing part 1 at one end, and passes through the joint fixing part 2 and the trajectory line slide rail part 4 in sequence at the other end, and is finally pulled to the fixed clamping part 3 for fixation, and connected to the sensor to simulate the motion trajectory of the virtual test of the aircraft engine.

[0062] The number of the fingertip fixing parts 1, the joint fixing parts 2, the fixing clamping parts 3, the track line slide rail parts 4, and the finger track lines 5 is the same as the number of fingers of the glove body.

[0063] The fingertip fixing part 1, the joint fixing part 2, the fixing clamping part 3, the track line slide rail part 4, and the finger track line 5 are all manufactured by 3D printing, with a short manufacturing cycle and low manufacturing cost.

[0064] The fingertip fixing part 1, the joint fixing part 2, the fixing clamping part 3, and the track line slide rail part 4 are all fixed on the glove body by gluing. In addition, for the glove body, conventional hard gloves can be used.

[0065] The utility model proposes an intelligent control glove for virtual testing of aircraft engines, which is equipped with an adjustable adaptive fingertip fixing component 1 at the fingertips, and the size of the component can be flexibly adjusted according to the thickness of the user's fingers. In addition, the intelligent control glove integrates a track-guided joint fixing component 2 at each finger joint to limit the motion path of the constraint track line to ensure that it moves in a predetermined direction. In order to further improve the accuracy of the operation, the intelligent control glove is respectively provided with a track line slide component 4 on each finger, which can retract and release the track line accordingly according to the bending movement of the finger. Finally, in order to stably install core components such as encoders and servos, the intelligent control glove is also equipped with a dedicated fixed clamping component 3 for each finger.

[0066] like Figure 1 As shown, the fingertip fixing part 1 has a first fixing hole at the bottom;

[0067] The joint fixing part 2 has a second fixing hole on its side wall;

[0068] The finger track line 5 has one end fixedly connected to the first fixing hole, and the other end passes through the second fixing hole in sequence, bypasses the track line slide rail part 4, and is pulled to the fixed clamping part 3 for fixed connection.

[0069] Figure 2 The structure diagram of the fixed clamping part according to an embodiment of the utility model is disclosed. Figure 2 As shown, a first clamping structure 31 is provided at one end of the fixed clamping part 3:

[0070] The first positioning structure 31 has a slide rail shaft 311 at its center for mounting the track line slide rail part 4 .

[0071] Figure 3a and Figure 3b The front view and the top view of the track rail parts according to an embodiment of the utility model are disclosed respectively. Figure 3a and Figure 3b As shown, a clamping hole 41 structure is provided at the center of the track rail part 4, and an effective connection with the fixed clamping part 3 is achieved by mutual clamping with the rail shaft 311.

[0072] Specifically, a clamping protrusion is provided at the end of the slide rail shaft 311 of the fixed clamping part 3. By passing through the structure of the card hole 41, the effect of clamping is achieved, so as to firmly connect the fixed clamping part 3 and the track line slide rail part 4 together.

[0073] The track line slide rail part 4 is a cylindrical structure, and the finger track line 5 is wound along the outer curved surface of the cylinder. The track line slide rail part 4 can realize the unfolding and folding of the finger track line 5 through the rotation action around the fixed clamping part 3 to meet different operation requirements.

[0074] As Figure 2 shown, a second clamping structure 32 is provided at the other end of the fixed clamping part 3:

[0075] The second clamping structure 32 is used to install and fix the encoder;

[0076] The encoder is connected to the finger track line 5 and rotates to a specific angle according to the movement of the finger track line 5, thereby realizing the corresponding adjustment of the encoder resistance value.

[0077] The encoder, as a precise sensor device, its core function is to measure and monitor the angular position or speed change of the motion system. Its working principle is to convert the mechanical position or motion state into a digital or analog signal that can be processed, so as to facilitate subsequent control and data processing.

[0078] In the application scenario of the intelligent glove, the encoder mainly undertakes the functions of position feedback and motion control: the position feedback function is used to accurately measure the bending angle of the finger to provide accurate force feedback; the motion control function can help monitor the motion state of the finger to achieve precise control and simulation.

[0079] The controller is arranged in the mounting area 6 on the back of the glove body and is connected to the encoder. It receives the rotation angle of the encoder and sends a control instruction to the servo motor, thereby adjusting the bending degree of the finger.

[0080] The controller calculates the bending degree of the finger through the rotation angle of the encoder driven by the received finger track line 5. It should be noted that different rotation angles of the encoder will directly cause corresponding changes in its resistance value.

[0081] In this embodiment, the controller is a development board. The mounting area 6 of the development board is located in the area on the back of the glove near the wrist. By configuring the development board in this area and relying on the written code, the intelligent control of the glove is realized.

[0082] As Figure 2 shown, a third clamping structure 33 is provided at the other end of the fixed clamping part 3:

[0083] The third card slot structure 33 is used to install and fix the servo motor;

[0084] The servo motor is connected to the controller and the finger trace line 5, and adjusts the angle limit and feedback force of the servo motor according to the control instructions of the controller, so as to realize the limit of the finger bending degree and realize the force feedback function.

[0085] Specifically, the servo motor has a limit function, and realizes the limit of the finger bending degree through the built-in control function, so as to realize the force feedback function.

[0086] It should be noted that in this embodiment, the tactile feedback actuator and the sensor are an encoder and a servo motor. By combining the encoder and the servo motor, the tactile experience and control accuracy of the simulation glove can be enhanced.

[0087] In other embodiments, in addition to the encoder, force sensors, position sensors, etc. can also be considered for the sensor. In addition to the tactile feedback actuator, servo motors, piezoelectric actuators, etc. can also be considered for the tactile feedback actuator. These components can be integrated with the controller as needed to achieve different types of force feedback effects.

[0088] An intelligent control glove for virtual testing of aero-engines proposed by the present utility model has highly flexible finger parts, which can move and bend freely to adapt to complex operation requirements; the part group inside the glove can accurately hold and control the finger trace line; in addition, the glove is also equipped with an encoder and a servo motor, and each finger is independently equipped with a set to achieve fine adjustment and feedback of motion control; the design of the motion trace line realizes the flexibility of free retraction and extension, further improving the convenience and efficiency in the testing process.
