固体发动机药柱公路运输随机振动响应分析

The random vibration response analysis of the solid rocket engine grain during road transportation

应用有限元法对不同路面、不同车速条件下整弹运输时某火箭发动机的随机振动响应进行了分析 ,得到了药柱内应力响应的分布规律及最大应力所在部位 。

Based on different grades of road excitation and transport speed, the random vibration response of the solid rocket engine grain during road transpotation is calculated with finite element method. The stress response distribution of engine grain is obtained, which provides a reliable basis for the grain fatigue damage analysis in the future.
