Two parametric excited nonlinear systems due to electromechanical coupling

Abstract This paper analyzes the behavior of two electromechanical systems. In the first part of the work, a simple system is analyzed. It is composed of a cart, whose motion is excited by a DC motor (motor with continuous current). The coupling between the motor and the cart is made by a mechanism called scotch yoke, so that the motor rotational motion is transformed in horizontal cart motion over a rail. The developed model of the system takes into account the influence of the DC motor in the dynamic behavior of the system. It is formulated as an initial value problem, in which the coupling torque between the mechanical and electric systems appears as a parametric excitation. By simulations, it is verified that the system has a periodic solution with a relation 2:1 between the period of rotation of the disk (part of the electromechanical system) and the period of the current in the DC motor. In the second part of the work, a pendulum is embarked into the cart. Its suspension point is fixed in cart, so that there exists a relative motion between the cart and the pendulum. The excitation of the pendulum comes from the motion of the cart, so it is not controlled and can vary widely because the pendulum can store energy. The pendulum acts as a hidden parameter of the system. The influence of the embarked pendulum in the dynamic behavior of the system is investigated and it is shown how it can affect the solutions of the dynamic equations.

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.
