摘要
火箭箭体的振动模态数据,以前主要是由全箭振动试验取得的,其实也可以由计算获得。本文阐述了用逐点计算法求解捆绑火箭模态的计算模型和计算方法,并对带助推火箭的火箭模态进行了分析。
Full-scall launch vehicle vibration test has been used as a main method for obtaining modal parameters of launch vehicle. This paper gives a algorithm (point by point method) to solve them, and analyzes the modal of strap-on launch vehicle.
