However, the development of laser speed measuring devices for measuring shells is not smooth. Many speed measuring devices cannot continuously measure the velocity changes of shells. Moreover, the speed of shells in rainy days will be affected by factors such as rainwater and the initial height of the chamber. Some common speed measuring It is difficult for the device to accurately measure the continuous change of the velocity of the shell in this situation, which brings a lot of trouble to the research work

Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings.
[0035] as attached figure 1 to the attached Figure 8 As shown in the figure, an interference-type artillery shell speed measuring device and a speed measuring method thereof include two rectangular support frames 1 vertically fixed on the ground 16, and slide rails are connected between the two rectangular support frames 1, and the slide rails Several groups of laser speed measuring devices are slidably arranged on the upper surface, and the adjacent groups of the laser speed measuring devices keep the distance. The laser speed measuring devices are convenient to move on the slide rail and adjust the speed measuring distance.
[0036] Including a water spray interference device, the water spray interference device is arranged directly above the slide rail, and the water spray direction of the water spray interference device is set perpendicular to the ground 16, and ...

The invention discloses an interference-type cannonball speed measurement device and a speed measurement method thereof. The device comprises two rectangular support frames vertically fixed on the ground. A slide rail is connected between two rectangular support frames. Groups of laser speed measurement devices are slidingly arranged on the slide rail. Adjacent groups of laser speed measurement devices are spaced. The device comprises a water spraying interference device which is arranged directly above the slide rail. The water spraying direction of the water spraying interference device is perpendicular to the ground. The device further comprises a cannonball launching device supported on the outside of an area formed by two rectangular support frames through a height adjustment supportdevice. The cannonball launching end of the cannonball launching device faces a plane formed by the rectangular support frames. The interference-type cannonball speed measurement device and the speedmeasurement method thereof can measure the continuous speed change of cannonballs launched from different heights under the interference of rain, and have the advantages of simple speed measurement and easy popularization.
Description
technical field [0001] The invention belongs to the technical field of cannonball velocity measurement, and in particular relates to an interference type cannonball velocity measurement device and a velocity measurement method thereof. Background technique [0002] With the development of science and technology, devices based on laser technology to test the speed of high-speed moving objects continue to emerge. However, the development of laser speed measuring devices for measuring projectiles is not smooth. Many speed measuring devices cannot continuously measure the speed changes of projectiles. Moreover, the speed of projectiles in rainy days will be affected by factors such as rain and the initial height of the bore. Some common speed measuring devices It is difficult for the device to accurately measure the continuous change of the speed of the shell under this condition, which brings a lot of trouble to the research work.
