Description
Technical Field
The invention belongs to the field of wind tunnel test devices, and particularly relates to a local wind field test device for a wind tunnel test.
Background
Wind tunnel test is an aerodynamic experiment method for understanding the aerodynamic characteristics of an object. In the field of civil engineering, a wind tunnel test method is often adopted, and a local wind field is tested by using an anemometer. However, due to the limitation of the number of usable instruments and the requirement of wind tunnel test, when performing local wind field test, a plurality of wind speed testers cannot be used at one time, so that the wind speed testers need to be moved and adjusted manually for many times in the whole test. The multiple movements of the instrument can drastically reduce the efficiency of the whole wind tunnel test, and the multiple adjustments of the instrument can make the test accuracy not consistent. And the position accuracy of the wind speed tester is difficult to guarantee by manual operation, so that the testing device for testing the local wind field is further improved.

The wind speed tester is fixed on the fixed support and used for testing the wind speed of the test object and transmitting the wind speed to the data acquisition instrument through the data transmission line.
The horizontal driving motor, the longitudinal driving motor and the vertical driving motor are connected with the logic controller through signal transmission lines and controlled to move by the logic controller.
The data acquisition instrument and the logic controller are connected with a control system computer. The control system computer has two working modes, namely a manual mode and an automatic mode; the manual mode needs to judge the test process manually, and the position to which the wind speed tester needs to move is input into the control software; the automatic mode needs to be preset, and a moving coordinate sequence of the wind speed tester is set.

Detailed Description
The invention is described in further detail below with reference to the figures and specific embodiments.
The structure of the local wind field testing device for the wind tunnel test is shown in figures 1-3: a longitudinal guide rail 3 is nested on the transverse guide rail 2, and a transverse driving motor 5 is arranged at the joint of the longitudinal guide rail 3 and the transverse guide rail 2 and is used for driving the longitudinal guide rail 3 to transversely move along the transverse guide rail 2; the vertical guide rail 4 is nested on the longitudinal guide rail 3, and the longitudinal driving motor 6 is arranged at the joint of the longitudinal guide rail 3 and the vertical guide rail 4 and is used for driving the vertical guide rail 4 to move longitudinally along the longitudinal guide rail 3; the fixed support 10 is nested on the vertical guide rail 4, and the vertical driving motor 7 is installed at the joint of the fixed support 10 and the vertical guide rail 4 and used for driving the fixed support 10 to vertically move along the vertical guide rail 4. The wind speed tester 11 is fixed on the fixed bracket 10, is used for testing the wind speed of the test object 1, and is transmitted to the data acquisition instrument 12 through the data lead 9.
The transverse driving motor 5, the longitudinal driving motor 6 and the vertical driving motor 7 are connected with a logic controller 13 through signal transmission lines 8, the logic controller 13 executes an instruction sent by a microcomputer of the control system, and the transverse driving motor 5, the longitudinal driving motor 6 and the vertical driving motor 7 move according to the instruction.
The data acquisition instrument 12 and the logic controller 13 are connected with a control system computer 14. The control system computer 14 has mainly two functions: one is to control the logic controller 13 to move the anemometer 11 to a designated position; and the second step is to control the data acquisition instrument 12 and acquire related data.
The specific working flow of the device is shown in fig. 4, and specifically comprises the following steps:
1. the test apparatus was installed in a wind tunnel laboratory, and the coordinate system and origin of coordinates were defined in the control system computer 14.
2. The operating mode is selected. When the manual mode is selected, the coordinates of the wind speed tester 11 are manually input, and the device moves and adjusts according to the input coordinates; when the automatic mode is selected, the automatic operation mode is entered.
3. In the automatic mode, a user needs to input a coordinate sequence of the wind speed observation instrument, wind speed sample acquisition time and a coordinate origin of the testing device.
4. After the data input is finished, the operation can be started. The system will preferentially detect whether it is located at the set origin, and if it is not, the system will require the user to adjust the device to meet the requirement of the anemometer 11 at the origin.
5. When the anemoscope 11 is located at the origin, the operation is performed according to the previously inputted anemoscope coordinate sequence and the wind speed sample acquisition time. The wind speed observer 11 is first moved to the user-specified position and, when in place, the control system computer 14 will control the data collector 12 to collect data. After the system determines that the data acquisition is completed, the control system computer 14 will search whether the execution of the coordinate sequence is completed, if the execution is completed, the experimental acquisition process is exited, and if the execution is not completed, the operation is performed according to the coordinate sequence.
The test device can automatically adjust the actual position of the wind speed observation instrument 11 according to the specific requirements of users, so that the purpose that the wind speed observation instrument 11 can quickly, automatically and accurately reach the designated position is achieved. Meanwhile, during the operation of the test device, all test data can be classified and stored according to the coordinate moving sequence, so that the orderliness of time distances is ensured.
