导弹起竖过程中的对地荷载研究

Study on the Load to Ground on Missile Erection Process

为提高导弹武器系统的生存能力和快速反应能力,对导弹起竖过程中的对地荷载进行研究。分析在导弹起竖过程中发射场坪所受载荷,将发射车视为左右对称体,在考虑风载荷影响的前提下,计算出导弹起竖过程中的前后支腿对地压力,为建立发射场坪的评估模型提供了载荷判据;利用压力检测装置采集导弹起竖时的支腿对地压力,得到了支腿压力随起竖角度的变化曲线,并以现场实测进行数据采集结果分析。分析结果表明:理论计算结果和压力幅值与变化趋势较为吻合,计算结果合理,可为导弹无依托发射的场坪选取和判断提供参考。

To enhance the survival capability and fast reaction capability of missile weapon system, study on the load to ground during the process of missile erection has been carried out. The bearing load of launching site is analyzed in missile erecting process with the hypothesis that the launching vehicle is bilateral symmetry object, and jack reaction force in erecting process is calculated while the influence of wind load is considered, which provides load criterion for building evaluation model of launching site. The running curve of jack reaction force related to erecting angle is yielded through using pressure data acquisition system, and the data acquisition result is analyzed with real measuring data. The analyzed result shows that amplitude and variation trend of jacks reaction force are in well match with theoretical calculation results, and the computatissile launching site when unsupported random launching way is applied.on result is rational, which can offer references for selecting and judging intensity of mi
