導(dǎo)讀：近日，在青藏高原，歷經(jīng)50多天的東方紅國四拖拉機(jī)海拔3500米試驗(yàn)圓滿完成。

　　【農(nóng)機(jī)網(wǎng) 明星企業(yè)】近日，在青藏高原，歷經(jīng)50多天的東方紅國四拖拉機(jī)海拔3500米試驗(yàn)圓滿完成。
 
　　國四切換的時間越來越近，中國一拖技術(shù)中心牽頭組織柴油機(jī)公司、大拖公司、中小拖公司等單位共同進(jìn)行國四標(biāo)準(zhǔn)實(shí)施前的最后一次國四高原試驗(yàn)。這次的高原試驗(yàn)中，他們分別要在海拔高度1700米、2500米和3500米的試驗(yàn)點(diǎn)，做好東方紅國四拖拉機(jī)的各項(xiàng)試驗(yàn)驗(yàn)證工作，保證東方紅拖拉機(jī)、柴油機(jī)各項(xiàng)性能符合各種氣候、地形等的使用要求。
 
　　從6月18日起，50多天的時間里，中國一拖高原試驗(yàn)團(tuán)隊(duì)在海拔3500米的極端條件下，實(shí)地采集試驗(yàn)數(shù)據(jù)，先后完成了10臺樣機(jī)累計(jì)140余次的試驗(yàn)項(xiàng)目，取得準(zhǔn)確數(shù)據(jù)，充分驗(yàn)證了東方紅產(chǎn)品不同配套路線的國四樣機(jī)性能，為東方紅產(chǎn)品研發(fā)和技術(shù)評估提供了充足的數(shù)據(jù)支撐。
 
　　3500米的高原上，不僅氣壓低、紫外線強(qiáng)，“天公變臉”更是家常便飯。由于高原上的試驗(yàn)場地大都是用帳篷來保護(hù)的，因此一旦出現(xiàn)狂風(fēng)暴雨的天氣，對試驗(yàn)人員來說都是一次“歷劫”， 高原試驗(yàn)團(tuán)隊(duì)負(fù)責(zé)人王曉飛說，我們不僅要面對各種技術(shù)上的難題，還需要面對惡劣自然環(huán)境帶來的未知挑戰(zhàn)。
 
　　此次試驗(yàn)中，YTN3、YTN5作為中國一拖最新研發(fā)的國四柴油機(jī)產(chǎn)品，包括基礎(chǔ)MAP標(biāo)定在內(nèi)的很多東西都是全新的，也是首次進(jìn)行高原試驗(yàn)，運(yùn)行過程中部分?jǐn)?shù)據(jù)存在大幅波動。為此，高原試驗(yàn)人員通過橫向?qū)Ρ确治鲈囼?yàn)數(shù)據(jù)，并不斷進(jìn)行嘗試，最終確認(rèn)了造成波動的原因。
 

       面對試驗(yàn)中的各類問題，試驗(yàn)人員一一解決。
 
　　此次試驗(yàn)驗(yàn)證，東方紅國四拖拉機(jī)各方面表現(xiàn)良好，特別是配東方紅6M發(fā)動機(jī)的LX2204拖拉機(jī)，更是在種種嚴(yán)苛的試驗(yàn)要求和標(biāo)準(zhǔn)下，一次性通過各種試驗(yàn)，表現(xiàn)出優(yōu)異的動力性和可靠性。

　　當(dāng)前，中國一拖已完成10臺東方紅樣機(jī)海拔3500米的試驗(yàn)任務(wù)，前往海拔2500米的試驗(yàn)點(diǎn)。從最難處挑戰(zhàn)，逐步向下兼容，一步一個腳印，一步都不能少，這就是中國一拖的務(wù)實(shí)態(tài)度和科學(xué)精神。
