火炮身管剩餘壽命評定方法的探討Study on assess ment of cannon barrel life by muzzle velocity of pill
彈丸初速評定火炮身管壽命研究This thesis takes cost estimating of domestic artillery weapon equipments as research object. on the basis of widely studying and summarizing the worldwidely existed achievements of theoretics and technologies of cost estimate, and according actual needs of the task, this paper establishes a suit of procedure for domestic weapon equipments " lcc estimate. then we provide the cost model for each phase of artillery equipments " life cycle
文章以我國炮兵武器裝備費用估算為對象,在全面分析了國內外費用估算已有理論知識和技術成果的基礎上,結合課題實際需要,建立了我國炮兵武器裝備壽命周期費用的估算程序;給出了炮兵武器裝備壽命周期各階段費用的總體模型。The use of the rapid - fire revolving barrel gun successfully solves the contradiction between high firing rate, long life time and small recoil, but on the other hand brings on a new problem to naval gun fire control system
摘要速射轉管炮的使用成功地解決了射速高、壽命長、后坐力小三者之間的矛盾,但另一方面也給艦炮火控系統帶來了新的問題。So we must estimate the lcc ( life cycle cost ) of artillery equipments with scientific methods, so that we can improve the efficiency of the acquisition and using cost
因此,必須科學地估算炮兵武器裝備的壽命周期費用,以提高武器裝備采辦效率和經費使用效益。In the paper, the projectile pushing process on firing is analyzed. the quantitative computational model of the projectile velocity to gun bore wear is built. finally, taking the 120mm gun for example, the relation of projectile velocity to gun bore wear is calculated, the phenomenon of trajectory peak is analyzed
分析了射擊時彈丸擠進過程,建立了彈丸初速下降量與炮膛內膛磨損量計算模型,並以某火炮為實例計算了該炮彈丸初速下降量與炮膛內膛磨損量之間變化關系,分析了彈道峰現象,為身管壽命預測提供理論依據。The special system is able to inspect and analyse the state of ablation, disfigurement of machine, bug of material and the degree of abrasion on the inner surface, which is an important instrument for make certain on remain life and shooting security of artillery body
該專用系統可對火炮身管膛內表面的燒蝕狀況、機械損傷、材質缺陷及磨損程度等疵病進行檢測與分析,是確定身管剩餘壽命及評價射擊安全性的重要手段。Thermal ablation wear is a key factor in deciding the life of a rapid - fire - gun barrel
摘要熱燒蝕磨損是決定速射火炮身管壽命的關鍵因素。The flame temperature is lower, thus giving a longer barrel life.
火焰溫度較低,因而可使炮管壽命較長。Gun tube life analysis and computation
火炮身管壽命分析與計算The outer surface temperature of barrel can be efficiently cooled down by adopting the outside cooling fluid method in a rapid - fire gun, but its effect on reducing barrel inner peak temperature and prolonging the life is limited
( 2 )對于速射火炮,外液冷方式可以有效降低身管外壁的溫度,但對于身管內膛溫度的降低和壽命的提高作用有限。分享友人
