摘　　要：对一种基于利用部分测点的遥测数据预示飞行器关键部位力学环境响应的方法进行了研究。建立了分析模型,能适应测点数小于结构模态阶数的工况。数值仿真结果表明:该法能重构飞行器结构的时域响应,可用于评估飞行器结构的力学环境,具一定的工程意义。The method to estimate the mechanical environment response of the key parts for spacecrafts by partly remote measured data was put forward in this paper.The analysis model was given out,which could deal with the case where the number of sensors was less than the number of modal orders used in computations.The simulation results showed that this method could reconstruct the time history of key parts of structures.It was useful in engineering.
