[0002] Maximum drive speed, a crucial servo performance indicator for weapon station artillery, primarily assesses whether the artillery can turn to its target position within a predicted timeframe. Therefore, testing the maximum drive speed of the weapon station artillery is essential during commissioning and testing. Current testing equipment utilizes high-speed photography, capturing the servo system's position and converting the number of frames into time to calculate the maximum drive speed. This method is complex and time-consuming in terms of preparation, high-speed photography, and data processing, requiring multiple personnel and a high level of skill. Differences in skill levels can lead to inconsistent data analysis results, resulting in low reliability. Furthermore, the high cost of high-speed photography equipment significantly increases testing costs. Therefore, there is an urgent need to design a new testing device to optimize existing testing methods. Summary of the Invention

[0025] A method for testing the maximum driving speed of artillery using the aforementioned weapon station artillery maximum driving speed testing device includes the following steps:

[0026] Step 1: Coaxially fix the laser pointer to the muzzle of the weapon station's cannon barrel, so that the panel with the photosensitive module on the test box faces the muzzle and is perpendicular to the barrel axis.

[0027] Definition: The distance from the panel with the photosensitive module on the test box to the center of the artillery's elevation and azimuth rotation is H; the distance between the upper elevation photosensitive module and the lower elevation photosensitive module is H.高低 The distance between the left-facing photosensitive module and the right-facing photosensitive module is H. 方位 ;

[0028] Step 2: Measure and calculate the elevation angle β and azimuth angle α;

[0029] The high-low angle β is the angle formed by the laser emitted by the laser pointer sweeping from the high-low upper photosensitive module to the high-low lower photosensitive module;

[0030] The azimuth angle α is the angle formed by the laser emitted by the laser pointer sweeping from the left azimuth photosensitive module to the right azimuth photosensitive module;

[0031] Step 3: Test and calculate the maximum driving speed for vertical downward, vertical upward, leftward, and rightward directions respectively;

[0032] (1) The test process for maximum driving speed in vertical and horizontal directions is as follows:

[0033] The cannon rotates from top to bottom, and the laser pointer follows the cannon to the high and low photosensitive modules. The high and low maximum drive speed test printed circuit board controls the stopwatch to start timing.

[0034] As the laser pointer continues its downward rotation with the weapon station's cannon to the high / low photosensitive module, the high / low maximum drive speed test printed circuit board triggers a stopwatch to stop timing. The time displayed on the stopwatch is the time t required for the cannon to rotate from the high / low upper photosensitive module to the high / low lower photosensitive module. 高低下 ;

[0035] According to formula V 高低下 =β / t 高低下 Calculate the maximum downward driving speed of the artillery.

[0036] (2) The test process for maximum driving speed in vertical and horizontal directions is as follows:

[0037] As the cannon rotates from bottom to top, the laser pointer moves with the cannon at the weapon station to the high and low photosensitive module, triggering the stopwatch to start timing on the high and low maximum drive speed test printed circuit board.

[0038] As the laser pointer continues to move upwards with the weapon station's cannon to the high / low upper photosensitive module, the high / low maximum drive speed test printed circuit board triggers a stopwatch to stop timing. The time displayed on the stopwatch is the time t required for the cannon to move from the high / low lower photosensitive module to the high / low upper photosensitive module. 高低上 ;

[0039] According to formula V 高低上 =β / t 高低上 Calculate the maximum upward driving speed of the artillery;

[0040] (3) Test process of maximum driving speed to the left:

[0041] As the cannon rotates from right to left, the laser pointer moves with the cannon to the right photosensitive module of the weapon station, triggering the stopwatch to start timing on the maximum driving speed test printed circuit board of the azimuth.

[0042] The laser pointer continued to rotate to the left along with the weapon station's artillery, reaching the left azimuth photosensitive module. The maximum azimuth drive speed test printed circuit board triggered a stopwatch to stop timing. The stopwatch displayed the time t required for the artillery to rotate from the right azimuth photosensitive module to the left azimuth photosensitive module. 方位左 ;

[0043] According to formula V 方位左 =α / t 方位左 Calculate the maximum driving speed of the artillery to the left in the artillery's azimuth direction;

[0044] (4) Test process of maximum driving speed to the right:

[0045] As the cannon rotates from left to right, when the laser pointer moves with the cannon to the left photosensitive module of the weapon station, the maximum driving speed test printed circuit board of the azimuth triggers the stopwatch to start timing.

[0046] The laser pointer continued to rotate to the right along with the weapon station's artillery, reaching the left azimuth photosensitive module. The maximum azimuth drive speed test printed circuit board triggered a stopwatch to stop timing. The time displayed on the stopwatch was the time t required for the artillery to rotate from the left azimuth photosensitive module to the right azimuth photosensitive module. 方位右 ;

[0047] According to formula V 方位右 =α / t 方位右 Calculate the maximum driving speed of the artillery to the right in the azimuth direction;

[0048] Step 4: If the maximum driving speeds for vertical elevation, vertical elevation, horizontal azimuth, leftward azimuth, and rightward azimuth obtained in Step 3 are all greater than the product design specifications, then the maximum driving speed of the weapon station's artillery is determined to meet the technical specifications.

[0049] Furthermore, in step 3, the maximum driving speeds for vertical downward movement, vertical upward movement, leftward movement, and rightward movement are average values ​​obtained from multiple tests using the same method.

[0050] Furthermore, in step 2,

[0051] According to the formula The elevation angle β is calculated.

[0052] According to the formula The azimuth angle α is calculated.

[0053] The advantages of this invention are:

[0054] 1. When using existing methods for measurement, a single weapon station cannon requires 7-8 people working together and at least 4 hours to complete the maximum drive speed test. Technicians also need a lot of time to analyze and process the data. The test preparation process, high-speed photography process, and data processing process are complex and time-consuming. However, when using the device of this invention for testing, it is only necessary to place the device about 5 meters away from the weapon station cannon's azimuth and elevation rotation center, fix a laser pointer at the cannon's barrel muzzle, and a single person can operate the weapon station cannon to run at maximum speed. The device of this invention automatically tests the running time, and it takes only 3 to 5 minutes to complete a total of 12 maximum drive speed tests in four directions: left (3 times), right (3 times), elevation up (3 times), and elevation down (3 times), greatly improving the testing efficiency.

[0055] 2. When using existing methods for testing, errors may occur in the results during photography or data analysis due to differences in the skill level of the operators. However, when using this maximum drive speed testing device, the system automatically displays the maximum drive speed, overcoming the problem of inaccurate data analysis results caused by human factors and greatly improving the accuracy of test results.

[0056] 3. In terms of economic cost, when using high-speed photography equipment for testing, the existing method costs about 1.6 million yuan per high-speed photography equipment, plus manpower and material costs; while using the device of this invention to test the maximum drive speed, a single person can complete the maximum drive speed test. The cost of each component, instrument, material and manufacturing of the device of this invention is about 200,000 yuan, which greatly saves the testing cost and the economic effect is very considerable.

[0096] The method for testing the maximum driving speed of the weapon station gun using the above-mentioned testing device includes the following specific steps:

[0097] Step 1: Installation of each component:

[0098] Reference Figure 7 and Figure 8 The laser pointer is coaxially fixed to the muzzle of the weapon station's artillery barrel. The test box is placed 5 meters away from the center of the weapon station's azimuth and elevation rotation. When the weapon station's artillery barrel is in a horizontal position, its direction is perpendicular to the front panel of the test box, and the axis of the barrel coincides with the center positions of the left azimuth photosensitive module, the left azimuth photosensitive module, the upper elevation photosensitive module, and the lower elevation photosensitive module.

[0099] Step 2: Measure and calculate the elevation angle β and azimuth angle α.

[0100] Reference Figure 9 and Figure 10 The elevation angle β is the angle formed by the laser emitted by the laser pointer passing through the upper elevation photosensitive module and the lower elevation photosensitive module, and the azimuth angle α is the angle formed by the laser emitted by the laser pointer passing through the right azimuth photosensitive module and the left azimuth photosensitive module.

[0101] In this embodiment, the physical installation distance between the left and right azimuth photosensitive modules is 600mm, and the physical installation distance between the upper and lower elevation photosensitive modules is also 600mm. The distance between the weapon station's gun azimuth and elevation rotation center and the center of the front panel of the test box is 5000mm. Therefore, the elevation angle β is equal to the azimuth angle α. The elevation angle β and azimuth angle α are calculated using the tangent inverse trigonometric functions:

[0102] The elevation angle β = 2*β / 2 = 2*arctan(300 / 5000) ≈ 6.867°

[0103] The azimuth angle α = 2*α / 2 = 2*arctan(300 / 5000) ≈ 6.867°
