In combination with sensitivity analysis, it is found that the main reason causing the fuse failure in bore is the lateral shock between the bourrelet and the bore surface. This shock produce huge lateral impulsive force and acceleration causing fuse mechanism plastic deformation and improper function. Besides, it may lead to fall-off in fuse safety.

造成引信瞎火的主要原因是由于彈丸在膛內(nèi)運動期間天天色天天日天天干，彈丸與身管內(nèi)壁間的相互碰撞所產(chǎn)生的橫向沖擊加速度使引信保險機構(gòu)產(chǎn)生多次重復(fù)振蕩51xx影院，使其產(chǎn)生局部塑性變形及破壞不能可靠解除保險所致；并可能導(dǎo)致引信膛內(nèi)安全性下降亚洲毛片免费基地。

In order to contribute to analyse and compute easily setback moving devices on the projectile fuzes,and to make the fuze devisers be able to get the approximate acceleration curves with a few parameters such as tube length and muzzle velocity of the guns,the displacement-time curve and velocity-time curve of gun interior ballistic are fitted with the Logistic models,then the formula of projectile acceleration curves in bore are gotten by the derivation of the formula of fitting velocity-time curve.

為了便于炮彈引信后坐運動機構(gòu)的分析和計算日本超级黄色视频网址，能使引信工作者只根據(jù)身管長度和炮口速度等少量參數(shù)就能獲得彈丸膛內(nèi)加速度近似曲線，運用Logistic函數(shù)擬合火炮內(nèi)彈道的位移－時間曲線和速度－時間曲線羞羞漫画看，再對擬合得到的速度－時間曲線求導(dǎo)便得到了彈丸膛內(nèi)加速度近似曲線肛交老妇。

In view of the short duration in the test of a fuze's self-destruction time,we discussed the possible factors such as fuze structure and processing quality,the angle of fire,weather and barrel conditions.Meanwhile,we used the method of variance analysis to process significance test for different barrel conditions on the malfunctioning of fuze self-destruction.After eliminating some other possibilities,we retrieved the fired shell which has abnormal band with fin,and finally found the real cause of the problem mentioned above.

由一帶離心自毀機構(gòu)引信自毀時間出現(xiàn)偏短的試驗結(jié)果出發(fā)，從引信結(jié)構(gòu)參數(shù)和加工質(zhì)量黄色网站免费久久久、射角黄色性视频网站、氣象條件、身管狀態(tài)等方面入手亚洲成年人免费网站一区二区三区，著重用方差分析法對身管狀態(tài)進行顯著性檢驗久久AAA级毛片免费看，探討引起引信自毀時間異常的因素，在逐一排除了其他因素后男女无遮挡羞羞视频免费软件，通過射擊回收的方法發(fā)現(xiàn)彈帶有異常飛邊国产二区精品，找出了問題的原因。
