Failure mode analysis of railway engine spring

The pattern of failure in railway engine springs can be obtained from life-test results, i.e., by testing a fairly large number of model until failure occurs, and observing the failure rate characteristics as a function of time. The first step, therefore, is to link reliability with experimental or field-failure data. These data will also provide a basis for formulating or constructing mathematically a failure model for general analysis. To assure coil spring integrity, failure analysis of broken coil springs is valuable both for the short- and long-term agendas of railway spring manufacturers and parts suppliers. This project describes different types of failure, failure analysis of spring, system reliability, reliability improvement and regions of failure. In this research work the failure data of spring is collected and then its failure density, failure rate reliability, graphical analysis, root cause analysis, Pareto analysis, system reliability and reliability improvement are separately calculated. This factor gives the different causes of failure and remedy over it.
