1、本科畢業(yè)設(shè)計(jì)(論文)題目:車載雷達(dá)液壓升降系統(tǒng)設(shè)計(jì)系別機(jī)電信息系專業(yè)機(jī)械設(shè)計(jì)制造及其自動(dòng)化班級(jí)學(xué)生學(xué)號(hào)導(dǎo)師2013年05月車載雷達(dá)液壓升級(jí)系統(tǒng)設(shè)計(jì)摘要隨著國(guó)際形勢(shì)的動(dòng)蕩,局部戰(zhàn)爭(zhēng)的不斷爆發(fā),現(xiàn)代武器裝備的不斷更新,現(xiàn)代戰(zhàn)爭(zhēng)已進(jìn)入了電子戰(zhàn),信息戰(zhàn)時(shí)代,傳統(tǒng)的機(jī)動(dòng)型雷達(dá)已經(jīng)不能滿足現(xiàn)代戰(zhàn)爭(zhēng)的需要。各國(guó)為了提高自己的防衛(wèi),跟蹤,識(shí)別和反擊能力,高機(jī)動(dòng)地面雷達(dá)應(yīng)運(yùn)而生。天線快速,可靠地機(jī)動(dòng)架設(shè)和撤收是車載雷達(dá)的基本要求之一。按傳動(dòng)系統(tǒng)的不同,雷達(dá)天線升降機(jī)構(gòu)可分為機(jī)電式和液壓式。與機(jī)電式相比,在輸出同樣功率的條件下,液壓式的體積和質(zhì)量小,承載能力大,可以完成較大重量雷達(dá)天線的架設(shè)
2、,還可大大簡(jiǎn)化機(jī)械結(jié)構(gòu),減少機(jī)械零部件的數(shù)目,也便于實(shí)現(xiàn)自動(dòng)控制。隨著科技的發(fā)展,液壓式傳動(dòng)系統(tǒng)已逐漸在雷達(dá)天線升降機(jī)構(gòu)中被采用。本設(shè)計(jì)采用一種翻轉(zhuǎn)式液壓舉升機(jī)構(gòu)及其液壓系統(tǒng),可實(shí)現(xiàn)對(duì)較大型天線的高架,并且在天線的舉升過程中,天線的姿態(tài)不變,架撤收過程平穩(wěn),可靠,快速關(guān)鍵詞:液壓升降系統(tǒng);汽車;雷達(dá);IThedesignofcarradarhydraulicupgradesystemAbtractTurmoilastheinternationalsituation,localwarsbreakingout,constantlyupdated,modernweaponsan
