Research On The Assembly Test Device Of Speed Up Train Bogie

The 25 T railway passenger train is a new type train with a speed of 160 km / h,which is widely used in the fifth speed increased.Speed-up train(such as the 25 T type train)using the CW-200 K type,SW-220 K bogies,these two types of bogies are used without bolster air spring device.But because these trains put into operation for a long time,the relevant maintenance equipment is not very mature,such as: the lack of passenger car bogie assembly test device,which gives the bogie high standard maintenance increased a lot of difficulties.At present,the relevant units within the railway train bogie repair assembly,the need to complete the installation of the vehicle,commissioning before the pressure test,assembly testing,once the fault,but also need to re-frame for processing,and then completed inspection,so reciprocating,both It is difficult to ensure the normal train maintenance progress,but also a lot of waste of human and financial resources.Therefore,the development of a speed-up train bogie assembly test device to reduce the completion of the vehicle after the completion of the failure to re-frame train handling on the impact of the train has become the railway train repair unit is facing an important issue.In this paper,the test equipment of bogie assembly for passenger train is taken as the research object,,first on the passenger car bogie test commonly used speed bogie assembly test methods are introduced and compared,the existing methods can not in the car before the completion of the Bogie Test and measurement data,easy because of the Bogie Test unqualified or data do not meet the requirements of new car rework,repair effect of node.Therefore,the existing detection methods of passenger car steering design frame assembly test device,in the design of a test station frame assembly area on the steering,making a through passenger car type door type bogie test device,can In the passenger car bogie air condition,the air spring constraint dimensions,and make the match in the car test conditions to meet the CW-200 K,air spring SW-220 K type passenger car bogie assembly,brake system air tightness test frame auxiliary air chamber,on both sides of the air spring pressure test,can the detection and test of bogie brake device performance of bogie of each dimension in the bus before the completion of the whole car reached prior to the completion of the bogie test device.Before and after the comparison of the data through the use of passenger car bogie assembly test,passenger car that the turn Compared with the existing technology to the frame assembly and test device,fault rate,data accuracy,the advantages of more reasonable and avoid node repair car.
