    Abstract
  • New structural scheme is introduced and design method is presented for a new rubber bumper of the railway freight car with 1 m wide trucks.The bumper is only made up of two exchangeable units, the butt plate rubber unit and the partition plate rubber unit.In addition, a zero initial press force is employed.These make the bumper holds advantages of light in weight, lowest in impact force and good in bumping effect.It is easy to be assembled and disassembled, good in exchangeability, lower in cost of manufacturing and maintaining and higher efficient in use of the bumper volume.The structural scheme provides also a capacity of developing the rubber bumpers used for high speed, sub high speed and heavy railway cars. The design method has been effectively applied to the development of present rubber bumpers.
