Helical springs are used as a suspension spring for the railway engine over the years. Railway locoshed maintainance department has observed that the suspension spring undergoes failure due to application of cyclic loads(i.e. static as well as dynamic load).The failure of spring is not uncommon,hence this calls for an study.Thus,the objective of this research paper is to study and formulate problem and analyse the causes of structural failure of suspension spring.To analyse the causes of structural failure we are using finite element analysis method(FEM).For analysis, we first prepare the design model of suspension spring according to details of design provided by Electric Locoshed Ajni,Nagpur,India.According to observation at site,the suspension spring fails at a much higher rate between first to third coil from the top end . Failure initiates at the inner radius of spring which progresses and shears the spring into two pieces. Thus, our study is around this matter.
