Finite Element Analysis And Structural Optimization Of Composite Orientation

The composite possesses many merits, for example, it have high Strength-to-density ratio, smaller density, be prone to contour machining etc. Multiple Launch Rocket System adopts the composite to make directional device, can lighten systematic weight greatly, improve the mobility of fighting, and reduce the costs. The composite has already been widely applied to the rocket, guided missile launcher abroad; At home, the composite will be used widely too in the Multiple Launch Rocket System.This thesis combines a new bounding rocket launch system research, uses the finite element method by ANSYS software, carry on the natural frequency, intensity, transient state dynamics analysis and structure optimization to the directional device which adopts the composite, have offered the reliable data consulting and certain theoretical foundation for further research of the directional device.
