Application of Reliability Technique for Developing a Test Methodology to Validate the Engine Mounted Components for Off-Road Applications under Vibration 2017-01-7004

Vibrational fatigue is a metal fatigue caused by the forced vibrations which are purely random in nature. The phenomenon is predominantly important for the components/systems which are subjected to extreme vibration during its operation. In a vehicle, an engine is the main source of vibration. The vibrational fatigue, therefore, plays a key role in the deterioration of engine mounted components. Multiple test standards and methodologies are available for validating engine mounted parts of an automobile. These might not be appropriate in the case of an off- road vehicle as the vibrational exposure of engine mounted components of an off-road vehicle is entirely different. In the case of an off-road vehicle, the engine mounted components are subjected to a comparatively higher level of vibration for a longer duration of time as compared to the passenger cars. In this paper, an attempt has been made to establish a methodology for validating the Exhaust Gas Recirculation system, an engine mounted component of an off- road vehicle using reliability as a tool. The derived methodology has been used for the lab test which is then compared with the field.
