本程序适用于地炮节制杆式驻退机后座反面问题计算。节制杆式驻退机结构形式很多,本程序的适用范围包括:一般的节制杆结构(即主流漏口由节制环与变截面的节制杆组成),和变沟槽的节制杆结构(即主流漏口由节制环与变深度的沟槽组成),以及变后座结构。不适用于短节制杆驻退复进机及其他形式驻退机。 计算时,膛内时期需已知内弹道诸元及膛压p与时间t的表格函数,后效期炮膛合力采用指数衰减的经验公式。计算液压阻力时,需已知驻退机实际的节制杆尺寸。
This program is applicable to the terra-cotto rod-type recoil machine back seat negative problem calculation. Restricted rod retiring machine structure in many forms, the scope of application of this program include: the general control rod structure (that is, the mainstream leakage by the control ring and variable cross section of the control rod composition), and change the groove control rod structure Leakage by the control ring and the depth of the groove), as well as the variable rear seat structure. Not suitable for short pole retreat machine and other forms of retreat machine. Calculation, the bore during the need to know the internal ballistic elements and bore pressure p and time t of the table function, post-mortem bore force using exponential decay empirical formula. When calculating hydraulic resistance, you need to know the actual spar dimensions of the recloser.
