DEVELOPMENT AND STRUCTURAL TESTING OF THE CLASS 87 LOCOMOTIVE BOGIE FRAME

The article first describes the basic requirements of this bogie design, and some of the constructional problems (particularly welding). It then describes: the study of stress levels in the various components by finite element stress analysis; the static and dynamic tests to which the prototype was subjected; use of a Perspex scale model to measure strains in the prototype; the method of computer calculation of the fatigue life of components under random cyclic loading. Similar methods of investigation have been applied successfully to a wide range of other structures, such as coach bodies, and tank wagon bodies.
