Two-wheeler has a provision for a sounding a horn to be used while commuting so as to warn the passerby of the approaching vehicle as well as a signal for maintaining a safe distance or to communicate for any other reasons for safety. The horn is crucial as it is directly related to safety and the malfunction may evoke secondary claims and may affect the good-will of the customer. In most malfunction problems of two wheeler horns is due to fatigue failure of spring in warranty period so it is important to calculate the fatigue life and reduce fatigue failure in its intended working period (i.e. before 3,00,000 cycles). A typical helical compression spring configuration of two wheeler horn is chosen for study. Life analysis determines fatigue life of spring by the safe stress and corresponding pay load of the helical compression spring. This work describes fatigue analysis of the helical compression spring is performed using NASTRAN solver and compared with analytical results. The pre processing of the spring model is done by using HYPERMESH software. The present work attempts to analyze the life using MSC fatigue software and also verified by experimentation. Life of spring found to be infinity using software analysis as well as experimentally. To extend life in place of present spring co-axial (series) spring is analyzed. Also factors affecting fatigue life of this compression spring are stated.
