According to the theory of dimension analysis , the basic thoughts and methods of dimension analysis modeling in the direction of practical engineering prblems are explored 摘要在量綱分析理論的基礎(chǔ)上,結(jié)合工程實(shí)際問題研究了量綱分析建模的基本思路和方法。
In this paper , charge calculating formulas and their relations of cutting chamber loose blasting are firstly analyzed with the theories of dimension , fluid dynamics . explosive dynamics , etc and the significance of the explosive factor in it is pointed out . calculating methods of the explosive factor are researched by law of conservation of energy , and then a new one is brought forward which proves to be rational and reliable by a sample 本文首先采用量綱分析、流體動(dòng)力學(xué)、功能平衡理論、爆炸動(dòng)力學(xué)等理論,分析了路塹硐室松動(dòng)爆破裝藥量計(jì)算公式及其內(nèi)在聯(lián)系,并指出k值在現(xiàn)有藥量計(jì)算公式中的重要性;在分析現(xiàn)有k缺陷的基礎(chǔ)上,利用能量守恒原理,研究了路塹硐室松動(dòng)爆破單位炸藥消耗量計(jì)算方法,并提出一種新的k值計(jì)算方法,實(shí)例驗(yàn)證本方法合理、可靠,優(yōu)于其它k值計(jì)算方法。
