在满足固体火箭发动机总体设计和推进剂设计一定的条件下,为了找出点火过程中导致冲击过载的影响因素,进行了若干不同状态的点火冲击试验研究,并进行了点火冲击过载频谱分析。试验研究结果表明:在点火具状态不变的情况下,点火压强随着点火药量的增大而增大;在点火药量较少、黑火药粒度较小的情况下,有利于减小点火冲击过载。

Under the same conditions of general design of solid rocket motor and propellant design, ignition research under different states and the frequency spectrum analysis were carried out in order to identify the infection factors of impact vibration. The results show that under a same ignition status, ignition pressure will increase by more gunpowder. Similarly, less gunpowder and less granularity of gunpowder are helpful for overloading of the ignition impact vibration.
