摘　　要：杆臂效应误差是因惯性测量组件安装位置与载体质心不重合而引起的,它是影响传递对准精度的主要误差之一。文中以速度匹配传递对准为研究对象,对杆臂效应产生的机理进行了详细地分析,采用设计低通滤波器和直接计算杆臂干扰加速度的补偿方案,对速度匹配传递对准中杆臂效应误差的补偿进行了对比研究,仿真表明两种补偿方法是可行的。Lever-arm effect error arises from anticoincidence between mounting position of the inertial measurement unit and mass center of vehicle. It is considered as one of main error sources of transfer alignment. Focused on velocity matching algorithm, the principle of lever-arm effect was analyzed in detail. The two compensation methods named designing low-pass filter and directly compensating lever-arm effect were proposed to eliminate the lever-arm error. The performance comparison concerning two methods was implemented for velocity matching transfer alignment through computer simulation, and simulation results show that the two compensation methods are both feasible.
