| Abstract | The micro-vibration monitoring and control of vibration-sensitive precision facilities are important and the accurate measurement of micro-vibrations is necessary. The piezoelectric sensors such as piezoelectric shell structure have better electrical-mechanical coupling properties and less effect of bulk and weight. This paper studies the response characteristics of an interceptive spherical piezoelectric shell under stochastic boundary micro-vibration excitations. The equation for electric potential is integrated, and the displacement is transformed and expanded to yield the ordinary differential equations for the shell. The frequency-response function, power spectral density and correlation function matrices of the shell system response are derived. Then the root-mean-square displacement, stress and electric potential of the piezoelectric shell can be calculated. The numerical results are given to illustrate the stochastic electrical-mechanical coupling properties and the relation between boundary electric potential responses and micro-vibration excitations. |

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.
