| Abstract | Methods of FOSM (first order and second moment) or MCS (Monte Carlo simulation) are not suitable for some complex mechanisms, especially those with the characteristics of high dimensions, low failure rate and highly nonlinear. Gear door mechanism is one of the most important subsystems in landing gear system of the aircraft, and many of its components and factors affect the close position accuracy. In this paper we focus on the close function failure mode of the gear door mechanism. At first the dimensional error of door's components and the mismatch error of hinges are defined as the basic random variables, the reliability model and performance function for close position accuracy of the gear door mechanism can be constructed. Then the IS (Importance Sampling) method is used to simulate samples for the performance function. At last, the reliability for the close position accuracy of gear door mechanism and its sensitivity about distribution parameters of every basic variable can be evaluated based on the simulation result. The result of analysis is helpful for its designing, design modification, reliability estimation and some problems that should be noticed in its employment and maintenance. |

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.
