摘　　要：配置方案是现有无陀螺捷联惯导系统研究中的薄弱环节,缺乏系统的设计理论和方法.从加速度计的输出方程着手,推导出角速度解算误差和加速度计测量误差之间的关系方程,其中配置方案参数为方程参量.以角速度解算误差最小化为原则,采用混沌粒子群算法,利用某型导弹的飞行数据得到了最优的六加速度计配置方案.针对其不易安装的缺点,通过参数设定,仿真得到了易于实现的次优配置方案.仿真结果表明其角速度解算误差接近于最优配置方案,明显优于国外经典的Cub-type方案.The research of allocation scheme is infertile in gyroscope free strap-down inertial navigation system（GFSINS） at present.There is no systematic design theory.The equation of angular-rate calculating error with measuring error of acceleration is deduced based on the output equation of an accelerometer,including the allocation scheme parameters.Minimizing the angular-rate calculating error as purpose,the optimal scheme with 6 accelerometers is presented by using chaotic particle swarm optimization algorithm and the flight data of some missile.For it is difficult to be installed precisely,an sub-optimal scheme is developed through restricting the parameters.The simulation result shows that its calculating error of angular-rate is close to that of the optimal scheme and much better than the typical Cub-type scheme.
