摘要
为研究警用车载九管发射器的动力学特性,避免武器发射和车辆行进时产生共振,影响武器的射击精度,利用CAD软件Pro/E建立发射器的三维数字化模型,运用有限元软件ANSYS建立有限元模型并采用Lanczos的方法进行模态提取,得到发射器的前6阶固有频率和振型,为九管发射器的优化设计提供依据,同时为其他非致命武器的动力学分析提供了方法的借鉴。
In order to study the dynamic characteristic resonance in weapons firing and vehicles traveling, ensure of vehicle-mounted nine-pipe ejector, avoid the shooting accuracy of weapons, this paper establish 3D digital model of the ejector by means of CAD software Pro/E, and establish finite element model by finite element software ANSYS, as well as extract the modal by means of Lanczos Consequently, the first 6 inherent frequency and vibration modes of the ejector obtained, which provided basis for design optimization, at the same time provide a method as reference in dynamics analysis of other non-lethal weapons.
