基于ModelCenter的顶置武器站稳定精度优化

摘要

The Overhead Weapon Station (OWS)has a system composed of complex types,and its interactive subsystems make it difficult to establish the optimization model of multidisciplinary collaborative simulation. In this paper,Adams is used to establish OWS mechanical system model and Simulink to the control system model,which are integrated in multidisciplinary design optimization platform ModelCenter. What's more,taking OWS stabilization accuracy as objective function,the first order difference model is used in sensitivity analysis of control system proportion coefficient and integral coefficient. Based on design exploration tool,optimization design of the parameters is carried out. The simulation results show that,the multidisciplinary collaborative optimization model of OWS stabilization accuracy has a short design period and high calculation efficiency,and provides technical support for optimization design of OWS multi conditions and structural parameters.%顶置武器站具有系统组成类型复杂、子系统间存在耦合作用的特点,导致多学科协同仿真的优化模型难以建立.通过Adams、Simulink分别建立了顶置武器站机械系统及控制系统模型,并在多学科优化设计平台Mod-elCenter中对该机电联合仿真模型进行系统集成;在此基础上,以顶置武器站稳定精度为目标函数,采用一阶差分模型对炮控系统比例系数及积分系数进行了灵敏度分析,并采用设计探索优化器对该参数进行了优化设计.仿真结果表明,所建立的顶置武器站稳定精度多学科协同优化模型设计周期短、计算效率高,为下一步进行顶置武器站多工况、多结构参数的优化设计提供技术支撑.
