Abstract | The paper describes the current research situation of automotive ride comfort from two aspects of experimental and simulation. The dynamics model with five degrees of freedom of a bus is established, meanwhile the kinetic equations is also derived according to D'Alembert principle. A road simulation model of class B is also established on the basis of white noise method. Combined with vehicle model and road model, the model of Matlab/Simulink is built. The vertical acceleration RMS on the seat is objective function and stiffness and damping of front and rear suspension are optimization variables. On the basis of GB/T4970-2009, the acceleration RMS is optimized in the speed interval of 50km / h and 100km / h. After been optimized, the RMS is reduced by about 10% and the effect is obvious at 60km / h. |

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.
