Preventing means stopping breakdown from taking measures ahead and it will shortening time of maintenance and break down of the machine and turn onrush maintenance into keeping machine sets in good condition, therefore, it ' s a good way to have equipment classified in abc and take a good advantage of limited equipment managing source to make point - check more functional
預防主要是為了防患於未然，變突擊維修為狀態維修，縮短維修時間和便於生產計劃的調整，減少停產損失。為此，對設備進行abc分類管理，以有效利用有限的設備管理資源；健全點檢制度，明確點檢內容，使得點檢工作更有成效；重視設備建設期的管理，掌握設備的初期狀態，既可節約建設期的費用，又利於生產期的費用的節約。 -
Involve in first level maintenance, assure stable qualified product, improve productivity and minimize production line down time
提高生產效率，穩定產品質量和參與初級維護，降低生產線停產時間。 -
In my thesis, i adopt the means rcm ( reliability - centered maintenance ) which is widely used in america. contrary to our ingrained notion that preserve maintenance ( pm ) is performed to preserve equipment operation, the primary objective of rcm is to preserve system function. by means of all kinds of pm, rcm preserve the function of the system at the most, at the same time it cut down the cost
本論文採用了目前美國比較流行的設備維護方式?以可靠性為中心的檢修（ reliability ? centerdemaintenance ） ，該檢修方式以維護系統功能為目的，改變了過去的維護設備狀態的思路，合理利用各種檢修方法，最大限度的保證了系統功能，同時也有效的利用了維修資金。 -
Above all, with the data acquired by tests, this thesis has analysized the lateral resistanc, longitudinal resistance and rail creep etc between ballast and sleeper before and after mass machine work, discussed the effect of mass machine on stability of continuously welded rail track, reseached the change regularity of fastening - down temperature of rail, which is resulted by mass machine work, and have settled the suitable range of work temperature which guarantees the stability of jointless railway. what ' s more, this thesis has put forward the appropriate work pattern, work temperature and work area for mass machine work in future. at the same time, this thesis has given rational suggestions about some conditions worth of attention in production of mass machine, which can in return raise the work productiveness of mass machine. at last, this thesis has considered formulating reasonable measures for operation organization and work standard, so that mass machine work can play an important role in maintenance, which can reduce work load, raise work efficiency and maintenance cost in daily maintenance
本文通過實測的各種數據，分別對大機作業前後道床對軌枕的橫向阻力、縱向阻力、鋼軌爬行情況等進行深入分析，進一步探討大機作業對無縫線路穩定性的影響，研究大機作業引起的鎖定軌溫的變化規律，確定保證無縫線路穩定的合適作業軌溫范圍。為我國今後的大型養路機械作業提出合理的作業方式、合適的作業軌溫和作業地段，同時對大型養路機械作業中應注意的問題提出合理化建議，為大型養路機械作業提供更高的安全保障，進一步提高大機作業效率。最後，對工務段在大機作業中的配合制定完善的施工組織措施及作業標準，使大機作業在養護維修中發揮更大的作用，為工務段日常的養護維修減少工作量，提高勞動效率，降低維修成本。 -
Mission - critical environments often require databases to be available continuously or for extended periods of time with minimal down - time for maintenance tasks
重要環境通常要求數據庫連續可用，或者在最短中斷時間內完成維護任務並在更長時間可用。 -
