摘要
研究了某新型阀控式火炮制退机的流场运动规律,以台架试验为背景,通过Fluent软件进行了等效流场分析,推导得出了主流流道液压阻力系数K的取值,并以某成熟的节制杆式制退机进行验证。研究了液压阻力系数K与流液孔面积ax的关系,K值在后坐过程中处于动态变化,其值为1.39~2.05,且随流液孔面积的减小而在一定范围内逐渐增大。建立了台架工况下的动力学模型,为后续制退机的台架试验。
The flow field motion law of a new valve-controlled recoil mechanism was studied.Based on the bench test,the equivalent flow field simulation was carried out by Fluent software.The method verification was carried out by a mature control rod type recoil mechanism.Through the research,the influence of the flow hole area axon the hydraulic resistance coefficient K was obtained.The value was dynamically changing during the recoil process,and gradually increases within a certain range as the flow hole area decreases.The hydraulic resistance coefficient K was derived from 1.39~2.05.The dynamic model under the gantry working condition was established for the bench test of the subsequent recoil mechanism.
