Research On The Launch Dynamics Of A Land-based Gatling Gun

The launching dynamic process of the land-based Gatling gun is the interactionprocess of a complex multi-body system. The paper was based on the multi-bodydynamics theory, the finite element theory, theory of rigid-flexible coupling dynamics,the Gatling gun vertical target dispersion model and particle kinematics theory. In thispaper, the issues on a ground-based Gatling gun launch dynamics and its verticaltarget dispersion was discussed. The paper provided a theoretical basis and referencefor the improvement of the structure design.The paper used the Solidworks software for land-based Gatling gun modeling toprovide accurately three-dimensional solid geometry model for dynamics simulation.This paper determined the Gatling gun components between land-based connection,imported the model into ADAMS established its coordinate system and imposed loads.The paper used the finite element software ABAQUS on the chassis and the carriageof the modal analysis, get returns to the rigid flexible coupling dynamic model of aLand-based Gatling gun in ADAMS software. The paper wrote a script file, simulatedthe dynamic gun system under two different conditions. The paper got the muzzleunder different conditions of vibration, Gatling gun recoil, each hydraulic support legin the horizontal plane of the mechanical condition of displacement and each supportleg stress condition. This article analyzed the result, obtained in the horizontaldirection in the horizontal when firing counter clockwise twist, the transversevibration of large and imaginary branch phenomenon support leg left front. Accordingto the artillery vertical target dispersion theory, the paper analyzed of the factorsaffecting the land-based Gatling gun muzzle disturbance. Through the reasonable assumption, without considering the attenuation of air resistance and velocity,considering the kinematics parameters of Gatling weapon special, the paper used theparticle kinematics law to established a vertical target model equations and got theresult of continuous firing200rounds of artillery shells at the500m Department offire intensity under the two different conditions. The results showed that under thecondition of lateral shoot gun dispersion is poor, and gave suggestions forimprovement.The land-based Gatling gun is still under the stage of development, experimentand improvement. Research methods used in this paper and the conclusions have beenobtained, provided a technological basis and reference for the further design andimprovement for land-based Gatling gun.
