The simulated projectile speed measuring system comprisesa simulated projectile and an acceleration measuring module, the acceleration measurement module is fixed inside the simulated projectile, the acceleration measuring module comprises a power supply circuit, an acceleration sensor, a signal conditioning circuit, a processor and a Flash; the simulated projectile is consistent with outer shape, size, gravity center and quality of the cased telescopedammunition, and the simulated projectile has a function of protecting the acceleration measurement module; the power supply circuit is used for providing required direct current for the rest circuitsof the acceleration measurement module, the acceleration sensor is used for collecting an acceleration analog signal in the impact extrusion process of the simulated projectile, after the acceleration analog signal passes through the signal conditioning circuit, an acceleration digital signal is sent to the processor, and the data is stored in the Flash. According to system, a complete speed measuring system for researching the cased telescoped ammunition impact extrusion process, the system has the advantages of being completely equivalent, recyclable, high in reliability, high in g value measurement and the like, and the system can be used for carrying out high-precision measurement on small signals in an impact extrusion process.

Description

technical field [0001] The invention belongs to the technical field of projectile impact extrusion process, and in particular relates to a simulated projectile speed measurement system for researching the impact extrusion process of countersunk projectiles. Background technique [0002] The countersunk ammunition is a special structural ammunition that shrinks all the projectiles in the cartridge, and the whole is a simple cylinder or other more regular shape. Compared with conventional ammunition of the same caliber, the countersunk bullet is small in size, light in weight, and has good overall performance. For small and medium-caliber automatic artillery systems, the use of countersunk ammunition will greatly shorten the total length of the ammunition and the feeding distance, and reduce the ammunition supply cycle time, thereby increasing the rate of fire while saving about 100% of the ammunition storage space and increasing the ammunition of the artillery system. carryi...

Problems solved by technology

Moreover, the impact and extrusion process of the submerged projectile occurs inside the projectile tube, and the short-term acceleration is very high, and the launch of the projectile is often accompanied by smoke and dust. Commonly used optical and Doppler effect measurement methods are difficult to apply or have large measurement errors. In addition, the actual submerged projectile The internal space of the projectile is extremely narrow, and the missile-borne measuring device cannot be built in, nor can it provide sufficient protection for the measuring system. These characteristics have brought great difficulties to the study of the impact extrusion process.
