Aerofoil Profile Analysis and Design Optimisation
Abstract: The aerofoil section is the incarnation of a wing or a lifting surface which is very important in an airplane wing design. While the shape of the aerofoil changes, their aerodynamic characteristics also change. This paper deals with a standard symmetrical aerofoil as reference and the effect of changes in shape due to minor variations in the coordinates. Eight new aerofoil shapes have been produced in this optimisation process. The …

Development and Simulation of Non-Linear Gear Dynamics Model
Abstract: With the development of high-speed mechanical transmission, the dynamic characteristics of gear transmission require continuous improvement and more accurate prediction of the gear system dynamics becomes more and more important. The literature revealed that the gear pair transmission system is inherently non-linear which exhibits complex behavior and it is significant to study its vibration characteristics in detail and to analyze the influencing factors. A nonlinear dynamic model of gear transmission …

Thermal Post-buckling and Large Amplitude Vibration Analysis of Composite Beams vis-Ã -vis Isotropic Beams
Abstract: Thermal post-buckling and large amplitude free vibration analysis of composite beams is directly investigated based on an analogous relationship derived from the behavior of isotropic beams. The applicability of simple analogous relationship derived for the use of composite beams is demonstrated for various layup schemes of symmetrically laminated beam with wide variety of boundary conditions. Numerical accuracy of the proposed approach show an excellent agreement with available finite element solution …
