tailieunhanh - Free vibration analysis of eccentric and concentric isotropic stiffened plate using ANSYS

In this paper free vibration analysis of eccentric and concentric stiffened isotropic plate with central stiffener and double stiffener has been studied and effect of various parameters such as boundary conditions, aspect ratio on non-dimensional frequency parameter of plate are investigated. | Free vibration analysis of eccentric and concentric isotropic stiffened plate using ANSYS Engineering Solid Mechanics 3 2015 223-234 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm Free vibration analysis of eccentric and concentric isotropic stiffened plate using ANSYS Harun Rashid Siddiqui and Vaibhav Shivhare Department of Mechanical Engineering Madhav Institute of Technology and Science Gwalior India ARTICLE INFO ABSTRACT Article history In the present world stiffeners are widely used to fulfill the requirement of high stiffness. Received 6 April 2015 Stiffened plates are used in most of the mechanical structures. In this paper free vibration Accepted 20 July 2015 analysis of eccentric and concentric stiffened isotropic plate with central stiffener and double Available online stiffener has been studied and effect of various parameters such as boundary conditions aspect 20 July 2015 Keywords ratio on non-dimensional frequency parameter of plate are investigated. Comparison of non- Free vibration dimensional frequency parameter for eccentric and concentric isotropic stiffened plate with FEM effect of number of stiffener at different mode shapes aspect ratios and boundary conditions Stiffened plate is studied using ANSYS parametric design language APDL code. A ten nodded element Natural frequency SOLID 187 from ANSYS element library is used for the discretization of proposed stiffened Aspect ratio isotropic plate. Convergence study of developed model with respect to the number of modes Boundary conditions has been done and results are compared from the related available published literature. Non Central stiffener dimensional frequencies are higher for fully clamped boundary condition for eccentric and Double stiffener concentric stiffened isotropic plate in comparison to other boundary condition. It is also seen that non dimensional frequencies are increases in a moderate value for eccentric and .
