火炮制退机的温升决定了能持续射击炮弹的发数,而精确计算每发射击后制退机的净吸收热量是很困难的。火炮连续射击时,若制退机的温度过高将影响后坐和复进的运动规律以及密封装置的性能。针对上述问题,以某火炮为研究对象,建立其物理模型,施加有关载荷和边界条件,通过AWE软件计算得到单发射击和连续射击后制退机的温度场及其散热的变化规律,并与传统计算进行比较和分析,为制退机的结构设计及射击试验提供参考。 Artillery recoil temperature rise determines the number of rounds fired can continue shooting, and accurate calculation of each shot after the rebound net absorption of heat is very difficult. Artillery continuous shooting, if the system back to the high temperature will affect the recoil and re-entry of the law of movement and sealing performance. In order to solve the above problems, a certain artillery was selected as the research object, and its physical model was established. The relevant load and boundary conditions were established. The temperature field and its heat dissipation of single gun and continuous gun were calculated by AWE software. The traditional calculation is compared and analyzed to provide a reference for the structural design and shooting test of the system.
