旋架式加速度過載模擬實(shí)驗(yàn)臺(tái)結(jié)構(gòu)設(shè)計(jì)與分析
摘要：導(dǎo)彈等飛行器特別是對(duì)對(duì)空發(fā)射等高質(zhì)量、高精度的武器，它們有很高的要求，要有很好的機(jī)動(dòng)性能，導(dǎo)彈的機(jī)動(dòng)性能越好，要求它的整體結(jié)構(gòu)強(qiáng)度就越高，承受機(jī)動(dòng)過載的能力越強(qiáng)，發(fā)動(dòng)機(jī)的結(jié)構(gòu)性能就要求越高，所以我們?cè)谏�產(chǎn)使用前必須對(duì)一些參數(shù)進(jìn)行實(shí)驗(yàn)性測(cè)試，這樣才能保證它在高空過載情況下正常放心使用，并且保證其誤差在允許范圍內(nèi)，因此，我們必須設(shè)計(jì)出相關(guān)儀器來測(cè)試出其參數(shù), 因此，所以發(fā)動(dòng)機(jī)過載模擬實(shí)驗(yàn)臺(tái)產(chǎn)生了。
 發(fā)動(dòng)機(jī)過載模擬實(shí)驗(yàn)臺(tái)是通過傳動(dòng)系統(tǒng)使固定在旋轉(zhuǎn)架上的發(fā)動(dòng)機(jī)轉(zhuǎn)動(dòng)而產(chǎn)生離心力，在過載情況下測(cè)試其某些性能參數(shù)的變化情況。通過離心機(jī)可以實(shí)現(xiàn)發(fā)動(dòng)機(jī)內(nèi)的彈道參數(shù)、離軸加速度、殼體應(yīng)變以及溫度等的測(cè)量.現(xiàn)主要工作就是系統(tǒng)的傳動(dòng)設(shè)計(jì)和測(cè)試件的夾緊。研究?jī)?nèi)容：了解該課題的特點(diǎn)以及發(fā)展?fàn)顩r.傳動(dòng)系統(tǒng)方案的設(shè)計(jì)、比較與確定.零件設(shè)計(jì)、選擇、計(jì)算以及圖紙的初步繪制,工件的夾緊方案的設(shè)計(jì)、比較與確定,生產(chǎn)部門討論加工問題.
 此次設(shè)計(jì)的實(shí)驗(yàn)臺(tái)在不作點(diǎn)火的情況下，對(duì)可兩個(gè)發(fā)動(dòng)機(jī)進(jìn)行測(cè)試，也可作單件測(cè)試。測(cè)試件一般在2m以內(nèi)，重量不超過100㎏，具有結(jié)構(gòu)簡(jiǎn)單、緊湊，工作可靠、維護(hù)方便等特點(diǎn)。實(shí)驗(yàn)臺(tái)的設(shè)計(jì)目標(biāo)是要滿足地面普通熱試車試驗(yàn)，在法向加速度作用下對(duì)飛行器進(jìn)行性能檢測(cè)，不至于導(dǎo)彈在機(jī)動(dòng)飛行中失效。

Rack centrifugal acceleration to overload simulation design
Abstract: The aircraft such as  missile is the high quality and precision weapon lauched by air to air .They have high requirement and have excellent maneuverability. The better maneuverability the missile have, the higher the intensity of holistic structure requires .The better it bear the mobile over loading,the higher the structure  capability of engine requires.To ensure that the missile can run normally in the case of high-position and overloaded, and also make sure that error is under control. We must hold a experimental test to some parameter before it is made and used.Therefore, we must design relative apparatus to test parameter and the overload simulation laboratory bench of the engine has been designed..
 The overload simulation laboratory bench of the engine is through the transmission system make the engine which install at the rotators shelf to rotate, that make the engine has the centrifugal force, tests its certain performance parameter change in the overload situation.pass left scheming can realize launch machine and leave the stalk acceleration, hull adapts to changes and the diagraph that temperature wait. Presently the main work is the system transmission design and measures the test sample clamping. The main study content include:learn the character of the task and the development trend,the design ,compare and confirmation of transmission system project, the design ,choice and calculate of part and the principium protract of blueprint. the design ,choice and calculate of the the project of clamp,the discussion of the problem of manufacture between production department.
 This experiment pedestal of design under the condition of not make some fire, to can two launch the machine to carry on the test, also can make a test.Test the piece generally at 2 m in, weight not over 100 Kg, have the structure simple, tightly packed, work dependable, support the convenience etc. characteristics. The aim of the design of this laboratory bench is to satisfy the common hot test-drive on the ground and to test the capability of the aircraft with the function of the vertical acceleration. The missile will not invalidation under this condition
Keywords:Leave the scheming    revolve the set        deliver the motive   over loading   invalidation
