Title Acoustic Array Expand Linkage Optimum Design
Abstract
Folding wings are widely used in various types of missiles or guided munitions, the key technology is designed to expand the agency.Taking the Brainpower Antitank Munition(BAT) as the background in this paper,the wings and acoustic array deployment mechanism were optimized designed with the Multidimensional optimization problem with constraints mathematical model.Using the sequential quadratic programming (SQP) method to solver the optimization model that selects the wing arm length and the deflection angle of the wing arm as design variables.Having reached the optimal value of the design variables,adjust expanding driving force to makes the airfoil and sound array components have a lower rotational angular velocity in the expanded operation at the beginning and end of the stage to make the wings expanded influence on missile flight attitude minimized .According optimization results,establish assembly model deployment mechanism within the pro-e software.And the kinematics and kinetic parameters of the components during the deployment were measured. The strength of the key parts is checked in the ANASY Workbench environment.
