Creation and Evaluation of Mini - Truck Accelerated Endurance Test Cycle 2013-26-0154

Products from the developed western countries are brought to India by different manufacturers. It is needed to look at the different aspects of the vehicles like performance parameters, structural stability, serviceability etc, as the requirement of the local market differ vastly from those requirement of the original markets. Indian market condition demands the vehicle suitable for taking the abuse load on the rough roads as the road conditions in the mofussil area and country side are bad.
This paper describes the definition and validation of the carryover products, to suit the Indian conditions by using different techniques, to reduce time to market.
This paper describes the creation of accelerated endurance test cycle for a mini truck which is representative of Indian customer usage of 120,000 km. Relative damage method is used for correlation of proving ground (track) with customer usage pattern on selected channels. In this method complete vehicle including structural parts of cabin, frame, suspension, spot welds and engine mounting is selected for correlation, compare to selection of only few sub system like suspension in similar work done in past.
This accelerated endurance cycle is evaluate by comparing parts failed during vehicle running on road (for engine durability) and vehicle running on track. As there is good match between parts failed on road and tracks both for failure modes and life, accelerated endurance test cycle is successfully evaluated.
