摘要/Abstract

摘要： 研究一种基于压缩气体静音发射的柔性气缸弹射器，实现了在约束且不爆破的情况下对弹射物变距离做功。通过弹射理论分析、仿真计算和实验验证相结合的方法，对柔性气缸弹射器动力学特性进行研究。结果表明：柔性气缸折叠压缩、充气展开弹射能实现对弹射物的发射，弹射过程无爆破现象；弹射器弹射能力受到柔性气缸初始长度、柔性气缸与弹射物的接触面积、柔性气缸压力等因素的影响。在对不同初始长度柔性气缸的弹射能力的研究中发现：柔性气缸初始长度越长、折叠量越大，柔性气缸展开弹射的作用距离就越大，弹射能力也就越强；通过4个1 000 mm×2 000 mm 规格的柔性气缸组在2 MPa压力作用下弹射质量60 t弹射物可产生4.6 MJ能量，可实现对大质量物体的弹射。该研究成果对实现高压气体可控能量释放与大质量弹射技术研究具有参考意义。

Abstract: A flexible cylinder launcher based on compressed gas mute launch was developed in order to realize to do work in changing distance to ejection object in the case of constraint and non-blasting. The dynamic characteristics of flexible cylinder launcher is studied through the analysis of catapult theory, simulation calculation and experimental verification. Results indicate that the flexible cylinder launcher can catapult the projectiles when it is folded, compressed, inflated and unfolded, and no blasting phenomenon exists during catapulting. The catapult ability of launcher is affected by the initial length of the flexible cylinder, the contact area of flexible cylinder and projectile, the pressure in flexible cylinder and other factors. The catapult ability of flexible cylinder with different initial lengths is researched. It is found that the longer the initial length is, and the more the fold number of flexible cylinder is, the longer the its catapult distance is, and the stronger its catapult ability is. Under the action of the pressure 2 MPa, a 1 000 mm×2 000 mm four flexible cylinder group which catapults a 60 t projectile can produce 4.6 MJ energy. It reflects that flexible cylinder launcher can realize to catapult large mass object. Key
