| Abstract | The macromodeling method for the nonlinear MEMS devices has become state of the art for fast component and system level simulation. A macromodel construction method is focused in this study for a nonlinear micro-plate actuated by a distributed electrostatic force, which is based on a modal projection method. During the construction of the reduced order model (ROM), the energy date are calculated by several finite element analysis running and a nonlinear function fitting scheme is used, thus an analytical model of kinetic energy, strain energy and electrostatic co-energy of the system have been achieved. Then the generalized motion equations of the rectangle plate represented in the term of a set of general mode coordinates can be obtained according to the Lagrange equation. This model order reduced method can take the effect of residual stress into account and has a low computational cost. Once the ROM of the device has been generated, it can be reused to simulate the quasi-state and dynamics behaviors of the device over a range of different electric driving waveforms. The calculated results show that the resulting ROM can capture the static/dynamic behaviors of the electrostatically actuated rectangle plate very well. |

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.
