In order to ensure the basic functions of bearing, the bearing design should first be based on functional requirements, predict its function was reduced by the yearly changes in the extent possible, the management must maintain a minimum function of a standard set of rules and to ensure the maintenance of this Standard inspection frequency and content, and to restore the function of the management plan has been reduced in advance to have a perfect overall maintenance management planning. Secondly, although the self-made according to the degree of change and development of fixed deformation corridor bearing steel, to predict lower bearing function, a single judge and selected the exact repair methods and implementation time, etc. In fact, not only depends on bearing itself changes, the information must also be full-bridge design, construction and maintenance and management of the past, some cracking and master, which is to ignore the important part. Meanwhile, on the methods used to record and save data. Should also be included in the overall maintenance plan and have clearly defined particularly important. In particular bearing maintenance and management, in addition to bearing after processing must be confirmed by a variety of experiments carried out to meet the energy requirements of parts of the car, bearing in use regularly in testing and maintenance, for laminated rubber bearings The main check there are no rubber bearing cracks, bearing the phenomenon of displacement and void if it is found should take timely and effective measures to deal with. At 5:46 on January 17, 1995 Kobe earthquake occurred in Japan, the focal position of latitude 34'34, the Kobe earthquake is a shallow inland earthquake, earthquake rupture along the strata along the extended reach Osaka Kobe 8km, crack width 0.2 m, the earthquake has the following characteristics. Near-field to get the maximum acceleration levels reached 600-800cm, vertical acceleration peak reached 300cm, near-field earthquake duration is 10-15s Corridor steel ball bearing hinges, excellent cycle varies by site, by the terrain affected significantly to the modernization of the Great Hanshin Earthquake in Kobe brought great disaster, because of the new route, the highway corridor bi-steel bearings, elevated railway, subway, viaduct collapsed, chips and serious break will ah, Port steel Corridor bearing, pier sinking tilt, causing traffic in addition to almost all aviation outside off, resulting in 5,466 deaths and economic losses of about $ 100 billion, since the 1923 Great Kanto Earthquake damage is most severe earthquake in Japan.
