減少此類事故發生的措施之一是:針對易受鳥撞擊的發動機等主要部件,從理論與實踐方面研究鳥撞擊的機理,對其進行結構、強度及性能的計算與試驗分析,指導工程設計,提高這些部件自身的抗鳥撞擊能力。As to the work about theory analysis, at first, the paper describes the atomizing and humidifying process of the centrifugal nozzle with firing pin type, high pressure and little aperture and liquid physical properties. later, combining with the structure characters of this kind of nozzle, the paper studies on the theory of the atomizing and humidifying process by three phases, which is water film forming phase, water film falling into pieces phase, and heat and mass transfer between water and air phase in turn
理論工作方面,首先描述了撞針型高壓小孔徑離心式噴嘴的霧化加濕過程和液體的物理性質,然後結合撞針型高壓小孔徑離心式噴嘴的結構特點,將其霧化加濕過程分三個階段進行機理上的研究,這三個階段依次為液膜形成、液膜初次破碎及二次霧化、水與空氣的熱濕交換。Mechanical impact dynamics is used to analyse the production and spread of stress wave when hydraulic pile hammer hammerblows piles, the stress wave influence the course of driving pile. slender hammer that is equal to wave resistance of the pile can bring ideal stress waveform. when the hammer weight is constant, efficiency of driving pile can be increased by means of selecting drive cap and cushion pad of different rigidity to match the hammer according to various geological condition and the pile. the structure and principium of hydraulic system of double - acting hydraulic pile hammer with double cylinders is studied in detail in the paper, the hydraulic system and electric control system of six - ton - double - actin hydraulic pile hammer with double cylinder is designed on the basis of it
本文應用沖擊機械繫統動力學分析打樁過程中錘體與樁撞擊時應力波的產生、傳播以及該波對沉樁過程的影響。認為與樁等波阻的細長狀錘體能夠產生理想的應力波波形;在樁錘重量一定的情況下,可針對不同的地質情況和樁,通過選擇不同剛度的樁帽和樁墊與其匹配來提高打樁效率。本文對雙缸雙作用液壓打樁錘液壓系統的結構和工作原理進行了深入的研究,並在此基礎上設計出六噸雙缸雙作用液壓打樁錘的液壓系統和電控系統。In the paper, we analyze the reason and effect of the bremsstrahlung, calculate the dose in the linear section of the storage rings, and propose the defense project to shield it
