The New Technique Of The Dynamic Balance Of The Wheelset Of The Rolling Stock

Along with improving the speed of rolling stock ,The balance property of wheelset will have influence directly to the vehicle's safe and run quality ,So the high-speed train must be tested to wheelset acording to the standard of railway ministrium .Althrough the decreasing weight and matching weight technique have been used,and the most of decreasing weight technique have been satisfied basically for safy and property in the production, but the wheelset intensity decreasing, demotion using and waster wheelset have appeared because of using decreasing weight and cutting technique. The dynamic balance and matching weight technique have a new basic theory for the improving of metal cold soldering technique ,So it will have an important. role in the study of dynamic balance technique of wheelset.First, it has been researched that includes the basic theory of dynamic balance , the balance principle and method of rigidity spheroid and combination spheroid, its balance technique has been clarified brief at the same time.Second , in allusion to analyze the decreasing weight technique having been applied in the mass of production, it has been introduced specially for testing and decreasing weight devices of dynamic balance, and analyzed for testing date and statistic date from the production line ,So the problem has been found in the decreasing weight technique so far.Third, on the base of being applied differently of epoxy resin ,this paper put forward the possibility of dynamic balance matching weight technology using new two composition epoxy resin , the matching weight technology experiment has been tested.Last, the project has been advanced that the decreasing weigh technology has been replaced by adhibiting matching weight technology after analyzing the effect and cost of two examine-repair decreasing weight .During the application of the 10 wheelsets dealed with the decreasing weight technique,it proves that this techique for rolling stock is simple to operat ,it saves time ,cost less ,and is worth to be popularized...
