微型(xing)高壓(ya)(ya)(ya)油(you)缸在(zai)太(tai)空(kong)探索設備中(zhong)的(de)技(ji)術適配面臨多重(zhong)(zhong)挑戰(zhan)。首先，太(tai)空(kong)中(zhong)的(de)真空(kong)狀(zhuang)態對依賴大氣壓(ya)(ya)(ya)工(gong)作(zuo)的(de)液壓(ya)(ya)(ya)系統(tong)(tong)(tong)提出了嚴(yan)峻(jun)考(kao)驗。由于(yu)缺乏空(kong)氣壓(ya)(ya)(ya)力支持，傳統(tong)(tong)(tong)液壓(ya)(ya)(ya)缸的(de)工(gong)作(zuo)機制(zhi)可(ke)(ke)(ke)能(neng)(neng)(neng)失(shi)效或性(xing)(xing)能(neng)(neng)(neng)大打折扣(kou)。因(yin)此(ci)需(xu)(xu)要(yao)對微型(xing)高壓(ya)(ya)(ya)油(you)缸進(jin)行特(te)殊設計(ji)以(yi)(yi)適應無氣壓(ya)(ya)(ya)環境工(gong)作(zuo)需(xu)(xu)求。此(ci)外，溫(wen)度(du)條件也是一大障礙：太(tai)空(kong)的(de)極低溫(wen)度(du)下液壓(ya)(ya)(ya)油(you)可(ke)(ke)(ke)能(neng)(neng)(neng)會凝固導致粘度(du)增(zeng)大進(jin)而影(ying)響其流(liu)(liu)動性(xing)(xing)與傳動效率；而高溫(wen)則可(ke)(ke)(ke)能(neng)(neng)(neng)導致材料性(xing)(xing)能(neng)(neng)(neng)退化甚至結構損壞(huai)等(deng)問題出現(xian)這些(xie)都需(xu)(xu)要(yao)采用(yong)(yong)耐(nai)溫(wen)度(du)的(de)特(te)種材料和(he)(he)(he)密(mi)封設計(ji)來克服以(yi)(yi)確保設備的(de)穩(wen)定(ding)運(yun)行和(he)(he)(he)可(ke)(ke)(ke)靠(kao)性(xing)(xing)提升。其次，微重(zhong)(zhong)力環境下確保良好(hao)的(de)密(mi)封性(xing)(xing)能(neng)(neng)(neng)和(he)(he)(he)防(fang)止泄漏至關重(zhong)(zhong)要(yao)；在(zai)地球(qiu)上受到重(zhong)(zhong)力作(zuo)用(yong)(yong)時(shi)微小泄露往往不易察覺但在(zai)失(shi)重(zhong)(zhong)的(de)條件下哪(na)怕是微小的(de)縫隙也可(ke)(ke)(ke)能(neng)(neng)(neng)迅速導致大量(liang)液體流(liu)(liu)失(shi)從而嚴(yan)重(zhong)(zhong)影(ying)響系統(tong)(tong)(tong)功能(neng)(neng)(neng)和(he)(he)(he)安全性(xing)(xing)因(yin)此(ci)必(bi)須設計(ji)出更(geng)為(wei)嚴(yan)密(mi)且可(ke)(ke)(ke)靠(kao)的(de)防(fang)漏結構和(he)(he)(he)監測(ce)系統(tong)(tong)(tong)以(yi)(yi)保障整(zheng)個系統(tong)(tong)(tong)在(zai)長期無人值守狀(zhuang)態下仍(reng)能(neng)(neng)(neng)維持穩(wen)定(ding)運(yun)轉還需(xu)(xu)考(kao)慮(lv)空(kong)間限制(zhi)及(ji)輕(qing)量(liang)化要(yao)求以(yi)(yi)滿足航天(tian)器搭載和(he)(he)(he)使用(yong)(yong)上的(de)嚴(yan)苛標(biao)準(zhun)這意(yi)味著在(zai)保證足夠強度(du)和(he)(he)(he)耐(nai)用(yong)(yong)性(xing)(xing)的(de)前提下盡可(ke)(ke)(ke)能(neng)(neng)(neng)通(tong)過優化結構設計(ji)選用(yong)(yong)輕(qing)質高強度(du)材料以(yi)(yi)及(ji)集成化技(ji)術等(deng)手段減輕(qing)整(zheng)體重(zhong)(zhong)量(liang)以(yi)(yi)便更(geng)好(hao)地服務于(yu)深空(kong)探測(ce)任(ren)務之需(xu)(xu).
