| Abstract | Main causes for fatigue and discomfort experienced by vehicle drivers during city driving were investigated computationally using a musculoskeletal modeling simulation method. Key adjustments of car seat (i.e., the seat-pan and back-rest inclination) together with various values of accelerator pedal's spring stiffness were analyzed in the present work. A public-domain rigid-body model of a seat together with the detailed full-body musculoskeletal model was used to study biomechanics of seated drivers. Interactions between the drivers and vehicle in various combinations of seat-pan/back-rest inclinations and pedal spring stiffness were analyzed using an inverse dynamics approach. To deal with the muscle redundancy problem, (i.e. the problem with the human-body containing more muscle than necessary to drive its degrees of freedom) the “minimum-fatigue” criterion [1] was utilized. The results show that seat-pan/back-rest inclinations and pedal spring stiffness have complex influences on the muscle activation and spinal joint forces of the human body. From the result, it may be suggested that a slight backward inclination of the seat-pan (approx. −20deg) and back-rest (approx. −20deg) may reduce the muscle fatigue of a driver. In addition, adding a spring (stiffness around 20Nm/rad) to the accelerator pedal does help in minimizing the muscle activity and spinal joint forces. |

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.
