Simulation And Analysis Of Dimensional Impact Acceleration Test

Artillery would still play an important role in the future wars, since it working as army’smajor fire. Currently most countries in the world are still working on research ofhigh-performance, intelligent and lethality new artillery. Since it would take a long process todevelopment a new artillery, it is vital for developing artillery and other weapons of massdestruction successfully to shorten the development period of weaponry and eliminatepossible defects during the development process.Currently, air-blast gun is used for testing the performance of new artillery. In this paper,a kind of missile-borne electronic test system is developed which is used for testing theperformance of air-blast gun and the projectile. Since of the special test environment,according to the technical requirements, corresponding protective measures were taken andappropriate originals were selected in order to improve the reliability of the system. Relevantparameters of the air-blast gun was successfully collected by the electronic test system.In this paper, each order vibration modes of the projectile was acquired by artilleryprojectile modal analysis with the help of ANSYS finite element analysis software, whichprovided the basis for analyzing the defects of the projectile’s structure and the failure of theprojectile when it launching. Meanwhile, the Natural frequency and each order vibrationmodes of the electronic test system was also acquired by ANSYS modal analysis, comparedwith the former results, the system would not interfere the test results. The data which ismeasured in experiment is processed by MATLAB software, and the validity of the dataprocessing is also proved related theory.Synthesizing the results of ANSYS modal analysis and MATALAB data processing, weverify the feasibility of the missile-borne electronic test system, and analyze the factors of theprojectiles’ failure.
