摘要
为保证光电平台视轴稳定精度, 在装配阶段需要通过配平来最小化其静不平衡力矩。为降低某两轴四框架形式机载光电平台的静不平衡力矩, 建立了一种多传感器布局优化设计方法。以各传感器的布局位置为变量, 基于有限包络圆方法实现各传感器间的不干涉约束, 快速得到具有较小静不平衡力矩的传感器布局方案。该方法成功将某光电平台关于内方位、内俯仰运动轴系的静不平衡力矩分别降低了45%和68%, 有效降低了配平质量, 提高了光电平台性能。
Abstract
To improve the optical axis stabilization,the static unbalance torque of airborne photoelectric platform must be minimized with the help of balancing weight in assembling stage.An effective layout optimization method of multiple sensors in the airborne photoelectric platform in two-axis four-gimbal form was proposed to reduce the static unbalance torque in the design stage.The finite circle method was employed to establish the module overlap constraint and the optimization algorithm of globally convergent method of moving asymptotes was used to solve the layout optimization problem fast.Results show that this method succeeds in reducing the static unbalanced torques of the inner azimuth and pitch axes by 45% and 68%, respectively,which effectively reduces the balancing weight and improves the performance of EO platform.
