Stress of a trunnion joint
2016 IEEE International Conference on Mechatronics and Automation, 2016Co-Authors: Bo Zhang, Ying Zhan, Sheng Feng, Haipeng Geng, Jian Zhou, Wenjie ChengAbstract:A trunnion joint is modeled as a circular plate with a rotational spring at the Outer peripheral portion to resist rotation. Asymmetrical bending deflection is produced when an external moment acts on the inner side of the circular plate. The equations of the circular plate with a special Outer peripheral boundary condition are derived. Choosing the stiffness of the rotational spring and the ratio of the Outer Radius and inner Radius of the circular plate as two parameters, the stresses consist of the radial stress, hoop stress and tangential stress are calculated. The effect of the stiffness of the rotational spring on the radial stress and hoop stress becomes obvious for a greater ratio of the Outer Radius and inner Radius. However, the tangential stress is independent of the stiffness of the rotational spring.

Free Vibration Analysis of Thin Circular and Annular Plate with General Boundary Condition
2015Co-Authors: S. Khare, N. D. MittalAbstract:This paper presents a numerical analysis of free vibration of thin circular and annular plate using finite element method. The first five natural frequencies are presented for uniform annular plates of various inner-to-Outer radii ratios, with nine possible combinations of free, clamped and simply supported boundary conditions at the inner and Outer edges of plates. The accuracy of the method is established by comparing the results available in the literature. Results show that natural frequency parameter increases as the inner-to-Outer Radius ratio increases except in case of free boundary condition, for which it decreases with the inner-to-Outer Radius ratio. Keywords: Circular and annular plate, Natural frequency, Mode shape, Finite element method Cite this Article: Khare S, Mittal ND.

Free vibration analysis of thin circular and annular plate with general boundary conditions
Engineering Solid Mechanics, 2015Co-Authors: S. Khare, N. D. MittalAbstract:This paper presents a numerical analysis of free vibration of thin circular and annular plate using finite element method. The first five natural frequencies are presented for uniform annular plates of various inner-to-Outer Radius ratios, with nine possible combinations of free, clamped and simply supported boundary conditions at the inner and Outer edges of plates. The accuracy of the method is established by comparing the results available in the literature. Results show that natural frequency parameter increases as the inner-to-Outer Radius ratio increases except in case of free boundary condition, for which it decreases with the inner-toOuter Radius ratio. This result provides benchmark values that can be used to validate result obtained by other approximate approaches such as finite difference method, differential quadrature method and boundary element method.

Axial stiffness of a rotating trunnion joint
Proceedings of the Institution of Mechanical Engineers Part C: Journal of Mechanical Engineering Science, 2014Co-Authors: Sheng Feng, Bo Zhang, Haipeng Geng, Lihua YangAbstract:A trunnion joint is modeled as a circular plate with two types of Outer boundary conditions. One is clamped supported and the other is simply supported. Symmetrical bending deflection is produced when an external force acts on the inner side of the circular plate. The governing equations of the circular plate with these two kinds of boundary conditions are solved by using finite difference method, and the axial stiffness of the circular plate is obtained according to the relationship between the external force and the bending deflection of the circular plate. In order to verify the accuracy of the finite difference method, a finite element method was also given. The effects of rotational speed and the ratio of inner Radius to Outer Radius of the circular plate on the axial stiffness are studied. It is shown that the rotational speed can significantly affect the axial stiffness of the trunnion joint for these two cases, especially for a lower ratio of inner Radius to Outer Radius of the circular plate.
