doi:10.12382/bgxb.2022.0183

Abstract

Abstract:

To meet the requirements of excellent multi-condition adaptability and dynamic performance index for the modular base of a weapon station, an efficient design method of multi-condition and static and dynamic reinforced wall structure for the modular base of the weapon station is proposed and verified. Firstly, the comprehensive objective optimization functions under multi-condition and multi-order modes are deduced, and the weights of multi-condition and multi-order modes are determined via the analytic hierarchy process and linear weighting method respectively. Then,a multi-condition and static and dynamic topology optimization method based on superelements is proposed to overcome the disadvantage of high computational cost under the comprehensive objective optimization function. At the same time, the response surface design and optimization method for the reinforced wall structure based on sensitivity analysis is proposed, which can reduce the topology optimization time of the modular base by 92% and the test design time of the response surface by 83.7%. Finally, the verification results shows that the modular base of the weapon station designed in this paper can not only adapt to a variety of working conditions but also has good static and dynamic characteristics besides meeting various performance indicators, which has some guiding significance for the reconfigurable efficient design of weapon station products.

Key words: reinforced wall structure, weapon station, modular base, multiple working-conditions, static and dynamic, superelements, sensitivity
