【成果簡介】

高耐(nai)熱負荷(he)動(dong)(dong)(dong)(dong)(dong)(dong)車(che)組(zu)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)盤(pan)(pan)包括高耐(nai)熱合金鋼制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)盤(pan)(pan)、碳陶(tao)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)盤(pan)(pan)和鋁陶(tao)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)盤(pan)(pan)三個品類，作為高速列車(che)關鍵核心零(ling)部(bu)件，制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)盤(pan)(pan)通過與閘片夾緊后的匹配作用(yong)，可(ke)(ke)將列車(che)的巨大動(dong)(dong)(dong)(dong)(dong)(dong)能(neng)轉變(bian)為盤(pan)(pan)/片摩擦熱能(neng)消散(san)在(zai)空氣中，使列車(che)在(zai)規定的制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)距離內實現減速或(huo)停車(che)，確保列車(che)安全(quan)運行。其中，高耐(nai)熱合金鋼制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)盤(pan)(pan)、碳陶(tao)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)盤(pan)(pan)可(ke)(ke)運用(yong)于既(ji)有動(dong)(dong)(dong)(dong)(dong)(dong)車(che)組(zu)和更高速度、惡劣工況條件運用(yong)動(dong)(dong)(dong)(dong)(dong)(dong)車(che)組(zu)，如400 km/h高速動(dong)(dong)(dong)(dong)(dong)(dong)車(che)組(zu)、川(chuan)藏線動(dong)(dong)(dong)(dong)(dong)(dong)車(che)組(zu)等車(che)型；鋁陶(tao)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)盤(pan)(pan)可(ke)(ke)運用(yong)于高速市域(yu)動(dong)(dong)(dong)(dong)(dong)(dong)車(che)組(zu)、城際動(dong)(dong)(dong)(dong)(dong)(dong)車(che)組(zu)、地鐵等車(che)型。高耐(nai)熱負荷(he)動(dong)(dong)(dong)(dong)(dong)(dong)車(che)組(zu)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)盤(pan)(pan)解決了高速動(dong)(dong)(dong)(dong)(dong)(dong)車(che)組(zu)制(zhi)(zhi)(zhi)(zhi)動(dong)(dong)(dong)(dong)(dong)(dong)盤(pan)(pan)裂紋失效、可(ke)(ke)靠性(xing)難題，在(zai)疲(pi)勞性(xing)能(neng)、散(san)熱性(xing)能(neng)、使用(yong)壽(shou)命(ming)、裂紋控制(zhi)(zhi)(zhi)(zhi)等方面均優(you)于國外(wai)產品，打破國外(wai)壟(long)斷，實現自(zi)給自(zi)足，目前技術成熟度為4級。
