Mechanism of electro-hydraulic exciter for new tamping device

Abstract A new tamping device which is driven by an electrohydraulic exciter was proposed to overcome the limitations of mechanically driven devices. The double-rod oscillation cylinder drives the tamping arm to realize vibration. A new spin valve was designed in order to fulfill dynamic state requirements of the oscillation cylinder. Parametric analysis was carried out by establishing mathematic model. Then, the relationships among the structure of valve port and the frequency, amplitude, output shock force of the cylinder were researched. An experimental device of the electrohydraulic exciter was established to validate the theoretical results. The signals were acquired by AVANT dynamic signal analyser of vibration. The results show that new tamping device can satisfy all kinds of complex working conditions with the flexible adjustment of frequency and amplitude.

About National Digital Library of India (NDLI)
NDLI logo

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.
