摘要/Abstract

摘要： 为了深入探究后后效期对轻型无后坐力炮动不平衡冲量影响的物理内涵，通过试验方法对某轻型无后坐力炮进行测试。在对测试结果进行分析基础上，结合振动系统运动稳定性理论建立相关数学模型。基于试验测试结果以及模型计算结果进行分析，结果表明：轻型无后坐力炮在发射过程中存在后后效期；振动系统运动稳定性理论可以用于轻型无后坐力炮后后效期剩余火药燃气对发射器动不平衡冲量影响机理的研究；低温条件下火药燃烧不充分，当出现不稳定燃烧时会导致发射器前冲。

Abstract: A light recoilless rifle was tested experimentally to deeply explore the influence of a period after an aftereffect period on dynamic unbalance impulse of light recoilless rifle. A relevant mathematical model is established based on the analysis of the test results and the motion stability theory of vibration system. The test and calculated results of the model were analyzed. The results show that there is a period after an aftereffect period in the launching process of light recoilless rifle. In the a period after an aftereffect period of light recoilless rifle， the motion stability theory of vibration system can be used to study the mechanism of the influence of residual propellant gas on the dynamic unbalance impulse of launcher. Under the condition of low temperature，the propellant combustion is insufficient，which may lead to the forward moving of the launcher.

Key words: recoillessrifle, dynamicunbalanceimpulse, aperiodafteranaftereffectperiod, vibration, launcherforwardmoving
