AB  - Crash buffers are widely used in railway
coaches to ensure that during sudden acceleration or
deceleration they provide sufficient reduction in vibration
and shock absorption. During exigencies like accidents
crash buffers helps in minimizing the physical damage to
coaches and human life by absorbing the shock energy. In
the present work, experimental and Finite Element
Analysis [FEA] had been performed on the standard
railway side (crash) buffers by using the deformation
element as a single component along with various design
modifications in buffer casing. The four proposed
modifications of conventional buffer casing were termed
as S1, S2, S3 and S4. In the planned deformation of the
modified buffer casings (deformation travel), it has been
observed that there is around 10-20% rise in energy
absorption than the conventional buffers with standard
spring action. Out of four design modifications the S4
buffer has shown the maximum load and crash energy
bearing ability. Energy absorption for S4 buffer increased
by twice as compare to S1 samples. Results obtained
exhibits the effectiveness of prototype crash buffer with
modified geometry over the conventional buffers useful
in minimizing the damage to railway coaches in case of
accidents to a greater extent
