摘要
利用随机振动复模态分析，提出了一种求解时变线性系统，在确定性激励与随机激励共同作用下非平稳随机响应的计算方法，并以舰载火箭武器系统为研究对象，用该法探讨了海浪对舰面火箭发射初始扰动和系统振动特性的影响．
Based on the complex modal analysis of random vibration, a computation method for solving nonstationary random response of timevarying linear system subjected to deterministic and random excitation is proposed. Taking shipbased rocket weapon system as a research subject, the effects of seas on the initial disturbance of shipbased rocket launching and system response characteristics are studied.
