- W2354520693 abstract "Aiming at drop piece phenomena of the solid motor grain,structural integrity of the motor was analyzed.Based on 3D viscoelastic finite element methods,taking a solid missile motor with umbrella-type grain as an example,finite element models of drop piece with different locations and sizes were derived,and Von Mises stress field of motor grain under internal pressure and axial acceleration load was calculated.The effects of solid motor grain drop piece on structural integrity were obtained.Grain fash drop piece has great effect on structural integrity,but front and rear fin drop piece has little effect.The methods and conclusions can provide technical reference for use and defect judgement of solid missile motor." @default.
