摘　　要：针对前混合式磨料水射流切割防暴弹的过程,分析磨料水射流对装药的切割安全性,探讨射流参数的选取及工程化处废的可行性。根据弹性力学的固体接触理论,建立磨料水射流冲击弹体时的数学模型,从而选取射流出口压力等工艺参数。依据射流的冲击理论和装药的热感度及撞击感度,结合射流作用时的升温试验,分析证实在该射流参数下的冲击安全性。结果表明,以手投催泪(或发烟)弹、枪射催泪(或发烟)弹为代表的4种防暴弹,其试验结果与实例计算相吻合,切割安全可靠度不低于98.57%。该研究可为防暴弹的工程化处废提供理论依据和技术支持。Aiming at the process of cutting anti-riot ammunition by former mixed abrasive water jet,the cutting safety of the abrasive water jet to the charge was analyzed,and the feasibility of the jet parameter selection and the engineering waste was also discussed. Depending on the rationale of solid contact of elasticity,the mathematical model of abrasive water jet impact missile was established,and the process parameters such as jet outlet pressure were selected. According to the impact theory of the water jet and thermal sensitivity and impact sensitivity of the charge,the impact safety of the jet parameters was confirmed by the temperature rise test when the jet was applied. Tear gas grenade,hand throwing smock bomb,gun tear gas grenade and gun smock projectile were used in the test. Results are in agreement with the calculation of the case,and the cutting safety reliability is not less than 98. 57%. The study can provide both theoretical and technical supports for the engineering waste.
