Description

Technical Field

[0001] The invention belongs to the technical field of electrical testing, and in particular relates to a maximum driving speed testing device and a testing method for a weapon station artillery. Background Art

[0002] As an important follow-up technical indicator of weapon station guns, the maximum driving speed mainly assesses whether the weapon station guns can be turned to the target position within the expected time. Therefore, the maximum driving speed of the weapon station guns needs to be tested during the debugging and testing process of the weapon station guns. The current test equipment uses high-speed photography for testing. The operation position of the weapon station gun follow-up system is photographed by high-speed photography, and then the number of high-speed photography frames is converted into time to calculate the maximum driving speed of the weapon station guns. The test preparation process, high-speed photography process and data processing process of this method are relatively complicated and time-consuming. It requires the cooperation of multiple people to complete, and the skill level of the test personnel is high. Different skill levels will lead to differences in data analysis results, making the test results unreliable. In addition, high-speed photography equipment is expensive, resulting in particularly high testing costs. Therefore, it is urgent to design a new test device to optimize the existing test methods.

[0040] (3) Maximum driving speed test process to the left:

[0048] Step 4: If the maximum downward driving speed, the maximum upward driving speed, the maximum left driving speed and the maximum right driving speed obtained in step 3 are all greater than the product design index requirements, it is determined that the maximum driving speed of the weapon station artillery meets the technical indicators.

[0049] Furthermore, the maximum downward driving speed, the maximum upward driving speed, the maximum leftward driving speed and the maximum rightward driving speed in step 3 are average values ​​obtained by performing multiple tests using the same method.

[0050] Furthermore, in step 2,

[0051] According to the formula Calculate and obtain the height angle β;

[0052] According to the formula The azimuth angle α is obtained by calculation.

[0053] The advantages of the present invention are:

[0054] 1. When measuring by the existing method, a single weapon station artillery requires 7-8 people to cooperate with each other and at least 4 hours to complete the maximum drive speed test. The 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 complicated and time-consuming. When the device of the present invention is used for testing, it is only necessary to place the device of the present invention at a position about 5 meters away from the azimuth and height rotation center of the weapon station artillery, fix a laser pen at the mouth of the weapon station artillery barrel, and operate the weapon station artillery at the maximum speed by one person. The device of the present invention automatically tests the operation time, and it takes only 3 minutes to 5 minutes to complete a total of 12 maximum drive speed tests in four directions: azimuth left (3 times), azimuth right (3 times), height up (3 times), and height down (3 times), thereby greatly improving the test efficiency.

[0055] 2. When the existing method is used for testing, due to differences in the skill levels of operators, there will be errors in the results during photography or data analysis and processing. However, when the maximum drive speed test device is used for testing, the system automatically displays the maximum drive speed, overcoming the problem of inaccurate analysis data results caused by human factors, and greatly improving the accuracy of the test results.

[0056] 3. In terms of economic cost, when the existing method uses high-speed photography equipment for testing, the price of each high-speed photography equipment is about 1.6 million, in addition to the labor and material costs; while the maximum driving speed test is carried out by the device of the present invention, a single person can complete the maximum driving speed project test. The cost of each component, instrument, material and manufacturing in the device of the present invention is about 200,000, which greatly saves the test cost and has a considerable economic effect.
