火炮立楔式炮闩抽筒系统的动态特性
Dynamic characteristics of extractor system in artillery vertical wedge breechblock
摘要
Abstract
Aimed at the faults such as cartridge jamming and component dynamic fracture in the extractor system of an artillery vertical wedge breechblock,this paper was focused on transforming the extracting fault analysis to the quantitative study of the system dynamic characteristics based on the nonlinear dynamics theory.The working mechanism of the extractor system was analyzed firstly,and then a continuous contact dynamics model was established for deriving out the motion law of any components and the impact loads quantificationally during the extraction process.Moreover,the elastic wave model of the lever-type extractor was established,which can both describe the dynamic stress distribution and achieve the influences of the mechanical parameters of the extractor by the quantitative form.The numerical calculation of those theoretical models and the simulations of the virtual prototype were both conducted on the ideal extracting condition.The comparison results of the same group show that the quantitative analysis dynamic models are reasonable and effective,which provides a theoretical basis for the solution of the extracting fault and the dynamics optimization of the extractor system.关键词
