|Abstract||Laboratory testing to validate the performance of vehicle components is a common practice in the automotive market. However, during standard bench testing of a commercial front wheel hub, several failures occurred in unexpected regions indicating an inconsistency with the vehicle cornering tests. This article addresses this inconsistency and presents methods for fatigue assessment using an accelerated rig (bench) test for a lightweight commercial vehicle front wheel hub. A complete cornering (figure of eight) vehicle test is modeled on a multi-body dynamic simulation system (ADAMS/Chassis) and the results are compared with the actual data obtained from the hub of a vehicle instrumented with a set of wheel force transducers. The multi-axial loading condition is successfully simplified due to the dominance of some stress components. Load data from the simulation are processed with the rain flow cycle counting algorithm. Critical locations on the C55 steel hub are determined with the stress analysis done on ANSYS (ANSYS Theory Reference: Release 10.0, 2005). Total damage is estimated by using the Palmgren–Miner linear damage summation rule. Finally, some validation test results are consistent with vehicle tests and may be used to substitute performance.|

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
