人體脊柱動力學模型的建立對研究飛行員彈射救生、傘兵跳傘開傘、著陸等脊柱損傷的生物力學以及研究人體脊柱耐受沖擊載荷的極限問題都具有重要意義.首先發展了凱恩方程的休斯頓方法,使其可應用於變形體連接的多體系統,並以此理論為依據建立人體整椎脊柱沖擊動力學模型,此時考慮脊柱的大位移運動,每個椎骨的變形相對椎間盤的變形小得多,把脊柱看成由剛體(椎骨)和變形體(椎間盤)組成的多體系統.並以大型真人坐姿沖擊實驗結果進行了擬合,最後得到腰椎間關節剛度系數因子和阻尼系數因子In this paper, firstly the macro parameter of the series connection app was comprehensively analyzed, among which the trajectory location of the bullet emission and the terminal velocity of the bullet were mainly analyzed, and the feasibility of the series connection app to cope with explosive reactive armor was demonstrated. and then the macro design about the head of the series connection app was made, among which a particular analyse about the bullet " s launching process was made, from which we concluded the relation between the thickness of the airproof loop and the velocity of the bullet detached from the carrier and the relation between the length of the bullet and the velocity of the bullet detached from the carrier and the relation between the length of the bullet and the burning rate of the powder and the relation between the length of the bullet and the maximum pressure of the emission hole and the relation between the length of the bullet and the emitting time of the bullet, and the reasonable str ucture of the head of the carrier and bullet were designed, then the intensity of the head of the carrier was checked out using of the software of ansys
本文首先對子母式穿甲彈總體參量作了全面的計算分析,其中主要分析了子彈射出的彈道位置和必要的子彈著靶速度,論證了子母式穿甲彈對付爆炸式反應裝甲的可行性,然後對子母式穿甲彈彈頭部進行了總體設計,其中主要對子彈的發射過程進行了詳細的分析,得出了母彈彈頭部發射孔內閉鎖環厚度與子彈飛離母彈速度的關系、子彈長度與子彈飛離母彈速度的關系、子彈長度與火藥燃燒率的關系、子彈長度與母彈彈頭部發射孔內最大壓力的關系以及子彈的長度與子彈發射所需時間的關系,設計出了合理的母彈彈頭部結構和子彈的結構,並利用ansys有限元分析軟體對母彈彈頭部的強度進行了校核。Second, by computing the trajectory of the missile and the method of analyzing cep, influences that the fighter ' s height, speed, pitch angle, the deflection angle between fighter and target, and the target moving characters make on the times of fighter attack and missile launch are deeply developed. third, by relating the motion of the missile and the fighter, the influences that fighter ' s dive angle and the deflection angle between fighter and target make on the attack field of the fighter are discussed in this paper when the fighter perform vertical and horizontal attack. criterion of attack effect is proposed focusing on attack time of the fighter, trajectory of the missile and destruction probability to the target
本文主要完成了以下幾個方面的工作:對導彈可發射區和飛機可攻擊區進行建模,通過對導彈彈道的模擬計算,並運用典型的圓概率偏差精度分析方法,詳細討論了飛機實施攻擊時,飛機的飛行高度h 、速度v 、俯仰角、與目標的偏離角_ x及目標運動特性等對飛機攻擊時機和導彈發射時機的影響;因此,將飛機和導彈結合起來,詳細研究了飛機在垂直平面和水平平面內實施攻擊時,飛機俯沖角和與目標的偏離角_ x對飛機的攻擊范圍的影響;以飛機實施攻擊的時間t 、彈道特性和對目標的殺傷概率p來評判對地攻擊的效果;最後給出典型算例,通過對空地攻擊過程的模擬實現,對飛機飛行過載提出要求。The development team, led by alliant techsystems corp, included heckler & koch ( h & k ) of germany, which won the contest to supply the 20 mm and 5. 56 mm gun mechanisms
彈道計算機同樣在彈藥發射時以電子方式提供數據設置彈藥的引信時間以保證它在飛行正確的距離之後引爆。The typical time - of - flight for a mortar round is from 20 - 30 seconds, so that must be accounted for when planning fires
迫擊炮彈一般的飛行時間為20 - 30秒,所以在計劃射擊時必須考慮這些因素。Becoming a proficient pilot takes time and is best done offline at first, with simple bombing scenarios and navigational drills to get you up to speed on how best to approach targets, navigate, deliver dumb ordnance, etc
要成為一個技術精湛的飛行員需要時間,並且最好從單機(網下)開始練習,從簡單的轟炸和飛行訓練到快速接近目標,操縱飛機,投射炸彈等。This paper researchs into the problem on fitting the shell flight - time of anti - aircraft gun by interpolation and quadratic approximation
摘要用插值擬合和最小二乘逼近擬合方法對高炮射彈飛行時間擬合問題進行了研究。Charlie flew 75 combat missions over vietnam before a ground - to - air missile hit his plane and blew it up. but he ejected, landed safely, and would spend six years as a vietnam prisoner of war. after the war, charlie returned home
在越戰期間,他參加了七十五次飛行任務,最後他的戰機被敵軍防空炮火擊落,但他及時從機上彈射而出,並安全著地,最後被囚禁了六年。But it has been long that the structure and shape of navy 37millimeter gun shrapnel do n ' t vary, so the main ballistic trajectory performance is poor, such as power n shooting precision flying time. these have been not able to adapt the need of modem weapon technology development for war field weapon equipment performance
但長期以來,海37毫米艦炮製式榴彈結構與外形等基本上沒有變化,因此,該彈的主要彈道性能,如威力、射擊精度、飛行時間等性能較差,已逐漸不能適應現代兵器技術發展對戰場武器裝備性能的要求。分享友人
