摘　　要：在调姿过程中,由于脉冲发动机的瞬态激励,飞行器会产生高频线角振动,影响末制导性能。为了通过地面试验真实对末制导系统进行性能考核,介绍了一种线角振动环境模拟试验技术。该技术利用多维振动试验方法,间接复现弹体的线角振动时域环境。研究结果表明,试验模拟真实性很好,具有较大的应用价值。In the process of attitude adjustment, because of the pulse transient excitation of the en- gine, the vehicle will produce high-frequency linear and angular vibration. It will affect the performance of terminal guidance. For the ground test evaluation of terminal guidance system, a combined linear and angular vibration environment simulation technology is introduced, which utilizes a multi-exciter/multiaxis test method, indirectly reproduces the missile body linear and angular vibration time history. The result shows that the authenticity of simulation is very good and has great value.
