【摘要】 本文以力学相似理论为基础，利用∏相似定理，对火炮内外弹道、火炮强度、火炮动力学、主要功能部件、炮位土壤建立了火炮全参数相似关系；确定了全系统各相似参数之间的相容性；首次创建了火炮全参数物理模拟理论。 研究解决了火炮大比例缩尺模型的设计方法和制造手段。 针对国家靶场定型试验中在副炮上进行的各项试验，首次研究了用模型炮代替副炮的多项目综合物理模拟试验技术。 利用建立的理论方法，以现有的GC45 155mm加榴炮为原型，作被模拟对象，按缩尺比例为1：6.738，缩小为23mm的模型炮。从现有制式发射药中选择合适的品种，作为模型的装药；设计了模型炮的弹丸，通过改装23mm弹丸和药筒而得到模型炮的实验弹丸和药筒；设计了模型炮的全部部件及其他相关的零件，并制造了模型炮用于射击实验。 在模型炮上进行了7个射击实验项目，实验项目包括：初速、膛压、后坐阻力、炮口制退器效率、炮口冲击波、动态应力、稳定性。测试并记录全部实验数据。 把模型炮实验获得的数据，按相似理论换算，并消除相似畸变带来的试验误差后，与原型炮在国家靶场定型试验的结果比较，证明了创建的火炮全参数物理模拟理论的正确性；证明所采取的大比例缩尺模型的设计方法和制造手段的可靠性；证明用缩尺的模型炮代替副炮进行多项目综合物理模拟试验技术是成功的。更多还原

【Abstract】 In this dissertation , based on the dynamic similitude theory and the п similitude theorem, the artillery full parameters similitude relationships of the internal ballistics, the artillery intensity , the artillery dynamic, the major artillery components ,and the emplacement soil were established. The mutually relationship of all parameters in the system was established .The full parameter artillery physical simulation theory was firstly established.The design of huge rate artillery model and madding methods were solved.Pointing to the second artillery in the national approval test, the test technology by physical model instead of the second artillery was firstly studied.The artillery of GC45 155mm was used as an archetype .It was shrunk at the rate of 1:6.738 to design a 23mm simulated artillery. An appropriate propellant was chosen from existing propellants. The pill and canister were designed by changing the prototype 23mm pill and canister. All components and parts of the similitude artillery were designed. Later, the artillery was made for shooting test.On the similitude artillery, 7 items of shooting tests were proceeded . These items included: muzzle velocity of projectile, pressure of gases, recoil force, efficiency of muzzle brake, muzzle Shockwave, dynamic stress, stability. All of the test data were recorded.The data got from the shooting tests, conversed by the theory of similitude and eliminated the system errors , were compared with the data from the approval test in the national shooting field . It verified that the full parameters artillery physical simulation theory was right . It verified that the huge rate model design and madding methods were reliable. It also verified that the test technology by physical model instead of the second artillery was succeed.更多还原
