Abstract

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
