摘要

半实物仿真系统的设计在导弹型号研制过程中可保证导弹动态性能优化,三轴转台作为仿真系统中复现导弹空中运动姿态的设备,其性能关系到半实物仿真系统设计的成败.为了研究三轴转台频响特性对半实物仿真系统设计的影响,首先建立转台传递函数模型,然后基于导弹纵向稳定回路给出二者相结合的半实物仿真控制结构,再详细分析转台指标对导弹频域及时域特性在半实物仿真系统中的影响,最后弹道仿真结果表明转台指标能够满足半实物仿真设计的需求.%As hardware in loop simulation system plays a more and more important role in the development of missile model,the influence of three-axis motion table is worthy of research.First,the three-axis motion table transfer function model was established,and the hardware in loop simulation control structure was discussed based on the combination of the model and the longitudinal stability loop.Then we analysed the influence of index table on missile frequency and time domain characteristics in physical simulation system in detail.Finally,the trajectory simulation results that the illustrate three-axis motion table can meet the accuracy demand of the hardware in the loop simulation.
