Description

Technical Field

[0001] This invention belongs to the field of wind tunnel testing technology, and in particular relates to a corrugated pipe type rapid response gust simulation device and method for wind tunnel testing. Background Technology

[0002] As an indispensable core equipment for airflow simulation in aerospace, automotive engineering, and building environment fields, wind tunnels have the core function of providing key experimental data for aircraft aerodynamic design, automotive aerodynamic optimization, and building wind load testing by precisely controlling airflow characteristics such as speed, pressure, and turbulence.

[0003] In wind tunnel testing, gust simulation is one of the important scenarios. It is mainly used to simulate the dynamic effects of sudden airflow changes such as atmospheric turbulence and strong wind impact on target objects. It is of key significance for testing the wind resistance stability of aircraft and analyzing the transient response of automobiles at high speeds.

[0004] However, traditional wind tunnels mainly rely on adjusting the speed of the fan motor to achieve sudden changes in airflow speed, thereby simulating gusts. However, this method of gust simulation has a slow transition time from calm wind to target wind speed, resulting in excessively long adjustment time. Furthermore, it cannot reproduce the millisecond-level step gusts in nature, thus resulting in insufficient dynamic fidelity of experimental data and failing to accurately reflect the transient characteristics of aerodynamics under real working conditions.

[0005] In addition, since the gust simulation uses a fan-driven airflow regulation method, it is necessary to change the airflow rate of the entire wind tunnel loop to achieve speed change. However, this process is limited by the airflow inertia in the pipe, resulting in a significant delay in speed change, which makes it difficult to meet the requirements of high-precision dynamic testing. Summary of the Invention

[0006] To address the problems existing in the prior art, this invention provides a bellows-type rapid response gust simulation device and method for wind tunnel testing. It abandons the use of traditional fan motors and introduces a linear motor as the driving device for gust simulation for the first time. It is equipped with a bellows-type pressure regulating mechanism, which greatly improves the response speed of gust simulation. It can reproduce the millisecond-level step gusts in nature and effectively improve the dynamic fidelity of test data, thereby accurately reflecting the transient characteristics of aerodynamics under real working conditions.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a corrugated pipe type rapid response gust simulation device for wind tunnel testing, comprising a wind tunnel test section, a wind tunnel stabilization section, a gust nozzle, a first corrugated pipe type pressure regulating mechanism, a second corrugated pipe type pressure regulating mechanism, a linear motor, and a force transmission frame; the wind tunnel test section and the wind tunnel stabilization section are connected in series; the gust nozzle is disposed between the wind tunnel test section and the wind tunnel stabilization section, with the large-diameter port of the gust nozzle facing the wind tunnel stabilization section and the small-diameter port of the gust nozzle facing the wind tunnel test section; the linear motor is fixedly disposed outside the wind tunnel test section, and the stator slide rail of the linear motor is distributed parallel to the central axis of the wind tunnel test section; the middle part of the force transmission frame is fixedly connected to the mover slide of the linear motor, one end of the force transmission frame is connected to the air inlet side of the wind tunnel stabilization section through the first corrugated pipe type pressure regulating mechanism, and the other end of the force transmission frame is connected to the air outlet side of the wind tunnel test section through the second corrugated pipe type pressure regulating mechanism.

[0008] The first bellows-type pressure regulating mechanism includes a first bellows, a first support ring plate, a first push-pull plate, and a first guide slide rod assembly. The first support ring plate is coaxially and fixedly mounted on the outside of the wind tunnel stabilization section. The first guide slide rod assembly is horizontally fixedly mounted on the first support ring plate. A through hole for the first guide slide rod assembly is provided on the first push-pull plate, and the first push-pull plate is mounted on the first guide slide rod assembly through the through hole. The first push-pull plate has a horizontal sliding degree of freedom relative to the first guide slide rod assembly. One end of the first bellows is sealed and connected to the first support ring plate, and the other end of the first bellows is sealed and connected to the first push-pull plate. The first push-pull plate is fixedly connected to one end of the force transmission frame.

[0009] A first vent hole is provided on the first push-pull plate, and a first valve is installed at the first vent hole.

[0010] The second bellows-type pressure regulating mechanism includes a second bellows, a second support ring plate, a second push-pull plate, and a second guide slide rod assembly. The second support ring plate is coaxially and fixedly mounted on the outside of the wind tunnel stabilization section. The second guide slide rod assembly is horizontally fixedly mounted on the second support ring plate. A through hole for the second guide slide rod assembly is provided on the second push-pull plate, and the second push-pull plate is mounted on the second guide slide rod assembly through the through hole. The second push-pull plate has a horizontal sliding degree of freedom relative to the second guide slide rod assembly. One end of the second bellows is sealed and connected to the second support ring plate, and the other end of the second bellows is sealed and connected to the second push-pull plate. The second push-pull plate is fixedly connected to the other end of the force transmission frame.

[0011] A second vent hole is provided on the second push-pull plate, and a second valve is installed at the second vent hole.

[0015] A method for simulating rapid gusts in wind tunnel testing using a corrugated pipe type, employing the aforementioned rapid gust simulation device, includes the following steps when using a low-speed gust mode:

[0016] Step 1: Adjust the moving slide of the linear motor to the left limit, so that the first bellows is in the maximum extension state and the second bellows is in the maximum compression state.

[0017] Step 2: Adjust the first valve to the closed position and the second valve to the open position;

[0018] Step 3: Install wind speed sensors inside the wind tunnel test section;

[0019] Step 4: Start the linear motor, causing the moving slide of the linear motor to move from the left limit to the right limit. Through the force transmission frame, the first push-pull plate and the second push-pull plate move synchronously to the right, so that the first bellows is in the maximum compression state and the second bellows is in the maximum extension state. The air in the first bellows is compressed and sprayed into the wind tunnel test section through the gust nozzle to form a gust. The gust is connected to the atmosphere through the opened second valve. During the formation of the gust, the moving speed of the first push-pull plate is recorded by the laser speed probe, the pressure in the wind tunnel stable section is measured by the first pressure sensor, the pressure in the wind tunnel test section is measured by the second pressure sensor, and the gust wind speed in the wind tunnel test section is measured by the wind speed sensor.

[0020] Step 5: Input the data measured by the laser speed probe, the first pressure sensor, the second pressure sensor, and the wind speed sensor into the database as a set;

[0021] Step Six: Repeat steps one to five, except that the output power of the linear motor is adjusted, thereby adjusting the moving speed of the linear motor mover slide to achieve synchronous adjustment of the moving speed of the first push-pull plate. The adjustment rule for the moving speed is to increase step by step until the output power of the linear motor reaches the maximum rated value.

[0022] Step 7: Summarize all data into the database. Each set of data corresponds to the output power value of a linear motor. Each set of data includes the moving speed of the first push-pull plate, the pressure in the wind tunnel stabilization section, the pressure in the wind tunnel test section, and the gust speed in the wind tunnel test section.

[0023] Step 8: Install the test object into the wind tunnel test section;

[0024] Step 9: Repeat steps 1 and 2;

[0025] Step 10: Set the gust speed, determine the output power value of the linear motor that matches the set gust speed, and then start the linear motor with the matching output power until the gust simulation is completed; at the same time, during the gust simulation, the real-time measurement data of the laser speed probe, the first pressure sensor and the second pressure sensor are compared with the matching data stored in the database to achieve indirect monitoring of the gust speed.

[0027] Step 1: Adjust the moving slide of the linear motor to the left limit, so that the first bellows is in the maximum extension state and the second bellows is in the maximum compression state.

[0028] Step 2: Adjust both the first and second valves to the closed position;

[0029] Step 3: Install wind speed sensors inside the wind tunnel test section;

[0030] Step 4: Start the linear motor, causing the moving slide of the linear motor to move from the left limit to the right limit. Through the force transmission frame, the first and second push-pull plates move synchronously to the right, causing the first bellows to be in its maximum compressed state and the second bellows to be in its maximum extended state. The air in the first bellows is compressed and then injected into the wind tunnel test section through the gust nozzle to form a gust. The air in the second bellows is depressurized by the sealing expansion, increasing the pressure difference on both sides of the gust nozzle during the gust formation process, thereby increasing the gust speed. During the gust formation process, the moving speed of the first push-pull plate is recorded by a laser velocity probe, the pressure in the wind tunnel stable section is measured by a first pressure sensor, the pressure in the wind tunnel test section is measured by a second pressure sensor, and the gust speed in the wind tunnel test section is measured by a wind speed sensor.

[0031] Step 5: Input the data measured by the laser speed probe, the first pressure sensor, the second pressure sensor, and the wind speed sensor into the database as a set;

[0032] Step Six: Repeat steps one to five, except that the output power of the linear motor is adjusted, thereby adjusting the moving speed of the linear motor mover slide to achieve synchronous adjustment of the moving speed of the first push-pull plate. The adjustment rule for the moving speed is to increase step by step until the output power of the linear motor reaches the maximum rated value.

[0033] Step 7: Summarize all data into the database. Each set of data corresponds to the output power value of a linear motor. Each set of data includes the moving speed of the first push-pull plate, the pressure in the wind tunnel stabilization section, the pressure in the wind tunnel test section, and the gust speed in the wind tunnel test section.

[0034] Step 8: Install the test object into the wind tunnel test section;

[0035] Step 9: Repeat steps 1 and 2;

[0036] Step 10: Set the gust speed, determine the output power value of the linear motor that matches the set gust speed, and then start the linear motor with the matching output power until the gust simulation is completed; at the same time, during the gust simulation, the real-time measurement data of the laser speed probe, the first pressure sensor and the second pressure sensor are compared with the matching data stored in the database to achieve indirect monitoring of the gust speed.

Step 5: Input the data measured by the laser speed probe, the first pressure sensor, the second pressure sensor, and the wind speed sensor into the database as a set; Step Six: Repeat steps one to five, except that the output power of the linear motor is adjusted, thereby adjusting the moving speed of the linear motor mover slide to achieve synchronous adjustment of the moving speed of the first push-pull plate. The adjustment rule for the moving speed is to increase step by step until the output power of the linear motor reaches the maximum rated value. Step 7: Summarize all data into the database. Each set of data corresponds to the output power value of a linear motor. Each set of data includes the moving speed of the first push-pull plate, the pressure in the wind tunnel stabilization section, the pressure in the wind tunnel test section, and the gust speed in the wind tunnel test section. Step 8: Install the test object into the wind tunnel test section; Step 9: Repeat steps 1 and 2; Step 10: Set the gust speed, determine the output power value of the linear motor that matches the set gust speed, and then start the linear motor with the matching output power until the gust simulation is completed; at the same time, during the gust simulation, the real-time measurement data of the laser speed probe, the first pressure sensor and the second pressure sensor are compared with the matching data stored in the database to achieve indirect monitoring of the gust speed.
